ANT: A Multi-Granularity Network Traffic Dataset and Benchmark for Agents Behavior Auditing ↗ 详情

Fan Li, Xiangyu Gao, Zixuan Liu, Tong Li et al.

Dataset 2026 2026-10-05 arXiv preprint arXiv:2610.06514 [cs.AI, cs.LG]; dataset and code released via an anonymized repository (anonymous.4open.science) at collection time arXiv:2610.06514 datasetbenchmarknetwork-trafficagent-auditingobservabilitysecurityagent-internet

The growing adoption of large language model (LLM) agents creates a need for network administrators and security teams to audit agent behavior within organizational networks without inspecting private user content. Network traffic offers an observable source of evidence, but how much it reveals about agent tasks and operations remains unclear. Existing traffic datasets lack the joint task and stage annotations needed to evaluate this question. We introduce ANT (Agent Network Traffic), a dataset providing agent behavior information at risk, scenario, and behavior primitive granularities alongside network traffic. ANT contains 3,114 execution episodes across 20 tasks and five scenarios, comprising 276,417 bidirectional flows and 40,049 behavior primitive segments organized into 47 macro groups. We establish a benchmark for agent risk identification, scenario recognition, and behavior primitive classification using 13 representative traffic analysis baselines. The results show that existing methods recover useful but uneven behavioral signals. They struggle to identify risk when malicious workflows resemble benign tasks and to distinguish scenarios with similar traffic patterns. Primitive classification is more reliable for frequent macro groups and those with distinctive traffic patterns than for rare or semantically similar groups. ANT provides a common basis for developing more precise auditing and forensic analysis of agent behavior from network traffic.

AI agents have increasingly interacted with external environments by invoking tools, with Model Context Protocol (MCP) emerging as a standard interface for connecting agents to heterogeneous tools and services. As organizations deploy agents at scale, MCP gateways have become a critical middleware layer for aggregating, governing, and shaping the tool surface exposed to agents. Despite the growing importance of MCP gateways in agentic systems, no prior work has systematically studied how gateway design affects agent capability, efficiency, and security. To address this gap, we introduce GatewayBench, the first unified evaluation framework and benchmark for MCP gateways. We characterize gateway architectures into two major paradigms: flattened gateways and hierarchical gateways. GatewayBench comprises 524 tasks across six domains, together with a pool of 11,118 real-world tools from 251 authentic MCP servers. To emulate large-scale deployments, we systematically inject task-irrelevant tools sampled from this pool into each agent environment, enabling controlled evaluation as the accessible tool surface scales. Based on GatewayBench, we conduct extensive experiments across seven widely deployed MCP gateways and diverse agent configurations, covering both benign and adversarial tasks. Our results reveal substantial differences across gateway designs in task completion, tool-use efficiency, and resilience to attacks, and further demonstrate that these effects interact strongly with the underlying model and agent harness. These findings highlight the MCP gateway as a consequential yet underexplored component of the agentic AI stack. By enabling controlled evaluation of gateway architectures under realistic tool ecosystems, GatewayBench provides both practical guidance for MCP gateway design and a rigorous testbed for developing more capable, efficient, and secure agentic systems.

From A2A Attacks to Envelope-Layer Defense: Red-Teaming Evaluation of LLM Agents and a Three-Layer Isomorphic Attack-Defense Model ↗ 详情

Yuelin Han

Paper 2026 2026-09-30 arXiv preprint (cs.CR) arXiv:2610.00392 A2AACPprompt-injectionred-teamingagent-securityenvelope-layer

Agent interaction protocols such as ACP and A2A have moved LLM-based agents toward multi-agent collaboration, introducing new security threats. A task sent by a remote peer over A2A is treated as a legitimate request, providing a natural channel for indirect prompt injection. Existing agent security evaluations mostly rely on a single metric, the attack success rate (ASR), and cannot distinguish whether an attack failed because the LLM recognized the malicious content or because a mechanism at the agent layer blocked execution. To address this, we propose A2A-TIBA, an attack principle combining indirect prompt injection with bypass circumvention. Through implant-command-exfiltration steps, it induces the target agent to deploy a callback interaction program, after which the attacker issues commands bypassing the agent. To evaluate defenses finer, we design GDA Measurement, a red-team testbed method using raw context capture via an LLM gateway, dual data preservation, and agent-based autonomous judging. We propose four attack outcomes, Class A/B/C/D, extending ASR into semantic refusal rate, semantic breach rate, interception rate, and penetration rate. Experiments reveal the envelope layer -- the channel through which malicious content enters an agent -- as a new defense dimension. We accordingly propose ELA-ITL, a three-layer isomorphic attack-defense model, dividing defense into envelope packaging, LLM recognition, and agent interception, and attack into implant channel, prompt optimization, and execution mechanism. Testing on 15 agent front-end x LLM back-end combinations and building a 1,000-case dataset verifies the attack effectiveness of A2A-TIBA, the evaluation validity of GDA Measurement, and confirms that adding malicious prompt labels to envelope packaging such as A2A, tool, and memory channels significantly improves LLM recognition of malicious content.

Why Do Agent Teams Fail Across Boundaries? A Failure Taxonomy for Agent-to-Agent Systems with Private States ↗ 详情

Paper 2026 2026-10-15 arXiv preprint arXiv:2610.19342 [cs.MA] arXiv:2610.19342 A2Amulti-agentevaluationinteroperabilityfailure-taxonomy

Agents are increasingly interacting with other agents that act for different principals (people or organizations on whose behalf they work), such as a buyer's personal agent negotiating with an enterprise's seller agent. In such agent-to-agent (A2A) scenarios, each agent has its own environment and holds information and authority that the other cannot see. Moreover, the interests of each agent may be aligned (cooperative), partly aligned (mixed-motive), or opposed (competitive). Existing multi-agent system failure studies assume one orchestrator, shared workspace, or single principal. We ask how A2A systems fail when these assumptions are removed. We study more than 2,500 recorded runs of A2A systems built from different agent harnesses and models, spanning 488 scenarios across eight families (legal, CRM, security, commerce, etc.). From these traces, we derive $A^2$-Failures, a taxonomy of 20 A2A failure modes in four categories: (i) discovery and delegation, (ii) grounding and record consistency, (iii) verification, and (iv) conduct and fidelity. Three findings hold across every harness, model, and scenario studied: (1) discovery and interaction are driven by the phrasing of the task rather than the availability of peer agents; (2) no agent verifies a peer's factual claim on its own initiative, so an A2A system inherits the reliability of its least reliable participant unless the protocol or mechanism performs the check; and (3) the aggregate outcome score credits the agent completing the task while staying blind to the coordination, verification, and conduct failures beneath it, so A2A systems must be evaluated per agent, against each agent's own principal. We release the run logs behind the taxonomy at https://huggingface.co/datasets/a2a-salesforce/a2-failures.

A2A-ForensicTrace: Offline Verification of Tamper-Evident A2A Runtime Evidence ↗ 详情

Paper 2026 2026-09-27 arXiv preprint (cs.CR) arXiv:2609.33924 A2Aforensicsauditevidencecross-organizationverification

Security-relevant Agent2Agent (A2A) executions can cross organizational boundaries, leaving investigators without live access to all participating systems. Offline investigation involves checking preserved records and their cross-record relationships for consistency. This paper presents A2A-ForensicTrace, an offline verification layer that converts runtime observations into typed records, derives protocol-relevant relationships, and commits both under an incident-trace root. An Ed25519-signed receipt binds the root and capture digest to the incident context. Evaluation comprised 240 executions through the official A2A software development kit (SDK), with actions selected by a large language model (LLM). These included 120 condition runs and 120 matched controls. All condition runs returned the expected bounded findings. No control produced an indication, and all roots and receipts verified. Median in-memory latency of the full offline verifier was 1.61 ms for the scenario traces. In the separate scaling experiment, it was 30.85 ms at 1,000 committed leaves. Future work will broaden A2A lifecycle coverage.

Agent Name Collision Attacks in Multi-Agent Systems ↗ 详情

Adithyan Arun Kumar

Paper 2026 2026-09-23 arXiv preprint (cs.CR, cs.MA) arXiv:2609.27624 A2Aagent-cardagent-namingidentityroutingsecurity

Multi-agent hosts turn remote Agent Cards into local agents, tools, workflow targets, and broker routes. A2A defines the card's name as human-readable metadata, not as a stable identity, and specifies no collision semantics. The security failure begins when a host nevertheless uses that remote name as a local routing identifier. We traced registration through dispatch and ran isolated regression tests at seven pinned open-source revisions. Six client-style integrations selected an attacker-controlled peer's client or loopback endpoint for a request addressed to a trusted peer's name. A seventh, brokered implementation collapsed both peers onto one name-derived route; queue and access-control state determine whether the result is interception or denial. The common result is wrong-peer dispatch, not universal privilege inheritance. Synthetic credential and tool tests found no A-specific credential transfer in the tested client bindings and no direct transfer of A-owned tools. The broker path forwards a caller-configuration object; delegated identity or tokens reach B only if present and B can consume the route. Two other paths expose a later, model-mediated decision rather than direct execution authority. The necessary conditions assign different responsibilities to the protocol, implementations, and deployments. Hosts should route by an origin-bound stable identity, keep names presentational, and reject ambiguous aliases. The evidence establishes a recurring implementation vulnerability class, not a universal A2A protocol exploit or a count of vulnerable deployments.

Agent Status Protocol (ASP): A Lightweight Specification for State Reporting in Multi-Agent Systems ↗ 详情

Diego Gosmar, Deborah A. Dahl, Emmett Coin, Csaba Bolyós et al.

Paper 2026 2026-10-15 arXiv preprint arXiv:2610.21538 [cs.AI](30 pages, 4 figures;v0.1 提案稿,非已批准标准) arXiv:2610.21538 agent-protocolA2Aobservabilityagent-governancespecification

The Agent Status Protocol (ASP) defines a lightweight way for heterogeneous AI agents to report their operational state to a status server, and for observers such as dashboards to receive that state as soon as it changes. Agents push small JSON events over HTTP POST; the server exposes the aggregated state to observers over Server-Sent Events (SSE). Because an agent that has crashed, hung or been compromised cannot be trusted to report its own failure, ASP does not rely on self-reports alone: the server infers liveness from missed heartbeats, can detect agents that are alive but no longer making progress, and accepts observations from supervisors, guardrails, operators and peers, some of which take precedence over what the agent says about itself while others are shown alongside it. ASP models state along independent dimensions (lifecycle, health, task, floor, governance), so that an agent can be, for example, online, degraded, working on a task and waiting for the floor at the same time. It reuses existing vocabularies: task states from the Agent2Agent (A2A) protocol, floor states from the Open Floor Protocol (OFP), and attribute conventions from the OpenTelemetry GenAI semantic conventions. This paper presents version 0.1 of ASP as a proposal, not as an approved standard. It is a working draft intended to open a discussion, and the authors invite comments, alternative proposals and independent implementations from the community.

Authorization Architectures for Tool-Using AI Agents ↗ 详情

Paper 2026 2026-09-14 arXiv preprint arXiv:2609.15906 authorizationtool-usesecurityarchitecture

Tool-using artificial intelligence (AI) agents, systems that autonomously invoke application programming interfaces (APIs), databases, browsers, and inter-agent protocols such as the Model Context Protocol (MCP), are becoming production infrastructure. Yet the security model governing when an agent is authorized to act on a human's behalf remains underdeveloped. Trustworthy human-AI systems require that every consequential agent action be traceable to a human principal, bounded by what that human actually delegated, and contestable after the fact; few documented deployments satisfy all three properties reliably and end to end. Existing literature addresses fragments of this problem in isolation, credential management for non-human identities, classical access control models, prompt injection, and audit trails, while giving little attention to the authorization decision point itself, the moment a tool invocation occurs, and mechanisms that make that decision correct, enforceable, and accountable. This review introduces a principal hierarchy spanning human user, operator/deployer, orchestrator agent, sub-agent, and tool endpoint as an organizing framework, and examines five interdependent layers: agent identity and credential lifecycle; delegation and scope propagation across multi-hop chains; runtime enforcement and just-in-time authorization at policy enforcement points (PEPs); prompt injection as an authorization bypass that breaks the principal hierarchy; and auditability, provenance, and non-repudiation. Drawing on a structured narrative review of 89 primary sources screened from approximately 180 candidates published between 2023 and 2026, we propose seven structural requirements, derive a four-layer reference architecture, apply the requirements to three deployable reference configurations, and identify runtime enforcement and aggregation bounds as the principal unresolved gaps.

The Cost of a Hop: Benchmarking NLIP and A2A ↗ 详情

Ranjan Sinha, Anindita Das, Ashika Anand Babu, Hari Palleti

Paper 2026 2026-10-02 arXiv preprint arXiv:2610.04053 [cs.AI] arXiv:2610.04053 agent-protocolA2ANLIPinteroperabilitylatencybenchmark

Autonomous agents built on Large Language Models (LLMs) need standardized protocols to interoperate across systems. Several now exist (A2A, MCP, ACP, ANP, NLIP), but the Natural Language Interaction Protocol (NLIP) has not appeared in any controlled performance study, and no work has measured where an agent protocol's latency is spent. We compare NLIP and the Agent-to-Agent (A2A) protocol empirically, decomposing latency into message creation, connection, and send phases across three independent hardware environments. For lightweight coordination, NLIP is 8.4-9.6x faster than the baseline A2A SDK implementation on two environments and about 4x on a third; the direction of the advantage is consistent, its magnitude depends on the hardware. The advantage is stage-specific: for the end-to-end pipeline, where LLM inference dominates, the protocols are near parity. The difference comes almost entirely from connection setup. To test A2A at its best, we also ran A2A SDK with connection caching enabled; caching narrows its gap with NLIP by a hardware-dependent amount, from 2.75x on one machine to near-parity on faster hardware, where at scale a cache-optimized A2A-SDK matches NLIP. We report these as measured conditions without a single causal account of the residual send-phase cost. Against the more optimized Python-A2A, NLIP leads by about 4x on the same stage. We close with a protocol-selection guide keyed to workload characteristics.

Crypto-bound identity-verified capability tokens for coordinating distributed AI agents: A proposal ↗ 详情

Srikumar Subramanian, Shubhashis Sengupta

Paper 2026 2026-09-25 arXiv preprint (cs.CR) arXiv:2609.30824 agent-identitycapability-tokenOAuthW3C-DIDdelegationauthorization

The prospect of fully autonomous transactional agents did not appear on the horizon until the advent of high capability language models. With such models, the operational benefits of adaptive task orchestration and independent (but constrained) decision making are tantalizing for enterprises and individuals alike. However, each such agent carries with it a serious attack surface in the form of prompt injection which can compromise any soft "guard rails" that may have been placed in context. The consequences of these attacks include credential ex-filtration which, if left unmitigated, renders the whole category of such agents unusable due to breach of trust. Furthermore, expecting a growth of autonomous agents, a security framework for them would require a form of decentralization to scale. Drawing on the proposed OAuth Agent Authorization Profile and the W3C DID and VC standards, we propose a framework based on the principles of capability based security with decentralized agent identity whereby agents access services based on tokens that are cryptographically bound to the agent's and issuer's identities and specify their scope. Services can validate that the delegation chain only involves scope attenuation before acting on any given token. We show that such a layer that lives outside the language model's context window in a secure module can enable agents to act within enforceable security boundaries.

Cryptographically Secure Agent-to-Agent Communication in Multi-Agent Systems ↗ 详情

Paper 2026 2026-10-16 arXiv preprint arXiv:2610.23078 [cs.CR] arXiv:2610.23078 agent-protocolA2Aagent-identityzero-trustpost-quantumsecurityDID

Multi-agent systems (MAS) comprise AI agents that collaborate or compete to perform complex, distributed tasks. Their dynamic interactions create opportunities for threat actors to target and impersonate other agents, intercept messages, inject malicious prompts, and exfiltrate sensitive data while simultaneously complicating the detection of anomalous behavior through conventional monitoring. This paper surveys threats and cryptographic challenges in agent-to-agent communication and presents a zero-trust architecture integrating identity, transport security, message integrity, and monitoring. The architecture establishes agent identities via decentralized identifiers and task-scoped verifiable credentials backed by a permissioned ledger, enforcing least-privilege authorization. For transport security, it provides mutually authenticated, crypto-agile TLS with hybrid post-quantum key establishment, and evaluates KEMTLS with pre-distributed public keys to reduce handshake overhead. Signed CBOR envelopes preserve payload integrity across multi-hop exchanges, while zero-knowledge proofs verify declared task constraints without exposing underlying inputs. Context-aware monitoring of inter-agent messages, tool activity, and execution telemetry informs the setting of risk-based trust thresholds and supports the detection of behavioral anomalies. Together, these mechanisms provide an integrated framework for securing and auditing agent communication, with implications for other agentic protocols and prospective 6G semantic communication.

Paper 2026 2026-10-12 arXiv preprint [cs.CR; cs.AI] arXiv:2610.17126 agent-identitydecentralized-identitySSIDIDdelegationaccountability

The rapid proliferation of autonomous AI agents in decentralized ecosystems challenges existing identity paradigms. While human identity is traditionally anchored in biological and/or self-asserted attributes and government credentials, AI agents lack a standardized definition of selfhood, creating critical gaps in trust and accountability. This paper introduces a novel framework for establishing Decentralized AI Identity rooted in Self-sovereign identity (SSI) principles. We propose a formal model that clearly distinguishes human users and AI agents, enabling distinct verification logic for each class while maintaining a unified identity calculus. The central to our contribution is the ABCD Framework, a multi-layered approach to agent identification and verification: (A) Algorithmic Fingerprint, which binds the identity to static model architectures and provenance; (B) Behavioural Fingerprint, which verifies dynamic performance metrics over time; (C) Cryptographic Identity, which anchors the agent via Decentralized Identifiers (DIDs) and (D) Delegation, which cryptographically binds agent actions to respective human accountability. By orthogonalizing these dimensions, we model how systems can enforce granular trust policies ranging from simple authentication to complex liability assignment, thereby solving the black box identity problem in the autonomous economic activities of AI agents.

Measuring Consensus in AI Agent Networks ↗ 详情

Paper 2026 2026-10-17 arXiv preprint [cs.MA; cs.AI]; accepted at the NANDA Workshop, IEEE TPS-ISA 2026 arXiv:2610.24833 agent-networkconsensusevaluationmulti-agentcommunication

As AI agents become increasingly connected through networks and take on tasks that require negotiation and joint decision-making, a systematic approach is needed to assess how their views converge and what information supports their decisions. We present an evaluation framework that treats consensus formation as the evolution of publicly stated positions toward a shared region, using accumulated communication history as context. The framework tracks position trajectories, group dispersion, and information expressed in public messages. Two case studies examine staffing decisions based on distributed facts and decisions requiring agents to reconcile duplicate information and a cancelled contract. Results from 1,872 completed runs associate sharing explanations with more accurate group decisions, while the second task reveals persistent disagreement despite accurate aggregate answers. Membership-change experiments provide a complementary evaluation. By separating convergence among agents from progress toward a task's full-information answer, the framework relates decision accuracy and bounded disagreement to the information available during the exchange.

Paper 2026 2026-09-03 arXiv preprint arXiv:2609.04135 protocolstandardnatural-languageinteroperability

AI agents are increasingly being developed and deployed across organizations using heterogeneous agent-development frameworks, AI models, tool interfaces, protocols, and execution environments. To realize their potential social and business impact, these agents must be able to interoperate through a common communication protocol. The Natural Language Interaction Protocol (NLIP), developed by researchers and practitioners across companies and universities and standardized by Ecma International, addresses this need by defining a standards-based application-layer protocol for AI-agent interaction. NLIP provides a lightweight semantic message envelope that can be carried over existing transports such as HTTP/HTTPS, WebSocket, and AMQP, while allowing NLIP-aware agents and gateways to adapt between clients, agents, local context stores, ontologies, tools, enterprise services, and heterogeneous underlying protocols. This paper presents the motivation and design rationale of NLIP, its message model and transport bindings, security-by-design considerations, reference implementation, representative applications, adoption signals, and relationship to emerging agent protocols such as MCP and A2A.

Trust Is Not a Score: Runtime Assurance Contracts for High-Risk AI Agents ↗ 详情

Serhii Zabolotnii

Paper 2026 2026-09-30 arXiv preprint arXiv:2609.39717 assuranceruntime-verificationriskagent-contract

Benchmarks, audits, and agent protocols describe performance, permissions, and repair, but not how observed evidence should change an agent's authority during a consequential task. We call this the assurance-transition gap. We propose a Runtime Assurance Contract (RAC), a policy-level formal schema binding autonomy boundaries, component eligibility, evidence state, transition policy, human-review capacity, and non-compensatory gates. Under RAC, soft metrics may inform routing, whereas a failed or unknown mandatory gate forces retry, switch, escalation, deferral, or stop; aggregate performance cannot authorize action. We define the contract, an evidence record, a permission rule, and five invariants, and illustrate them in clinical, industrial, and judicial failure probes. We then report a deterministic failure-injection study in agentic coding: 280 constructed cases evaluated by a gate conjunction, a score-only rule, and a restricted protocol baseline. At the published example weights and threshold, the score rule admits 80 of 100 block-required injections and all 40 review-required injections. Tuned in hindsight, it matches the conjunction on this corpus. For positive weights, a positive threshold, binary risk signals, zero-signal controls, and an injected case firing each signal alone, we show that exact agreement holds if and only if the threshold does not exceed the smallest weight. A separate set of 18 hand-authored traces checks version-pinned evidence and review transitions against simpler policy variants. In a further prospective synthetic holdout of 24 episodes, two blinded LLM judges assign identical labels to all 72 action attempts; RAC and a separately implemented full stateful baseline both match these labels. These studies test mechanisms on synthetic cases; they establish neither deployed safety nor cross-domain effectiveness.

SPFR: Semantic Potential Field Routing for the Distributed Internet of Agents ↗ 详情

Yeguang Qin, Liangqi Peng, Fengxiao Tang, Ming Zhao

Paper 2026 2026-08-26 arXiv preprint arXiv:2608.25396 routingsemantic-routinginternet-of-agentsdistributed

In a distributed Internet of Agents (IoA) without centralized routing control, routing tasks to capability-matched executors is challenging because destinations are not predetermined and agents have bounded local service views. Discover-then-forward approaches, by contrast, select an executor before network forwarding and therefore do not directly support reselection when additional candidates become visible downstream. We introduce Semantic Potential Field Routing (SPFR), a distributed IoA routing algorithm that integrates executor discovery and reselection into hop-by-hop forwarding. SPFR represents each executor visible in a local semantic forwarding information base (FIB) as a task-conditioned semantic potential source, with utility setting its strength and hop distance inducing exponential attenuation. At each hop, the forwarding agent recomputes these potentials, reselects the dominant executor, and forwards the task one hop toward it. Under task-consistent frozen-FIB conditions, we prove loop freedom and finite-hop termination and derive an explicit additive error bound under bounded visibility relative to the full-visibility objective. Extensive simulations on real-world topologies show that SPFR approaches the realized utility of distributed utility-greedy routing and request-triggered global discovery while using fewer forwarding hops and substantially fewer request-triggered messages, and remains robust under network and service dynamics.

SSR: Structural Signal Retriever for Scalable Agent Discovery in LLM-Orchestrated Multi-Agent Systems ↗ 详情

Paper 2026 2026-10-15 arXiv preprint arXiv:2610.21113 [cs.MA] arXiv:2610.21113 agent-discoveryagent-registryagent-cardretrievalorchestrationevaluation

Large-scale multi-agent ecosystems require mechanisms for discovering suitable agents without exposing entire registries to a large language model (LLM) orchestrator. The challenge is not only to retrieve relevant Agent Cards from a growing registry, but also to maintain a compact candidate context, since each additional candidate increases prompt size, inference cost, latency, and the risk of exceeding the model context window. We formulate this problem as candidate-context scalability and propose the Structural Signal Retriever (SSR), our deterministic and training-free retrieval method designed for Agent Card discovery. SSR derives structural lexical signals from capability-bearing Agent Card fields, weights them using inverse document frequency (IDF), and uses an Inverted Signal Index (ISI) for selective candidate scoring. We evaluate SSR using a synthetic agent benchmark, a public MS MARCO adaptation, and end-to-end LLM orchestration. At 1,000 agents, SSR reduces LLM input by 98.8% and orchestration latency by 70.9% relative to full-catalog orchestration. On MS MARCO, IDF improves retrieval effectiveness within the structural representation, while the ISI preserves retrieval effectiveness and reduces explicitly scored passages by 96.8%. End-to-end experiments show that candidate pre-selection maintains a compact candidate context as registry size grows and avoids the operational failures observed with full-catalog orchestration. These results support SSR as an Agent-Card-native, traceable retrieval mechanism for candidate-context scalability.

A Scalable Trust Discovery Architecture for the Internet of Agents ↗ 详情

Song Zhang, Jiankang Yao, Hongtao Li, Xiaojun Zhang et al.

Paper 2026 2026-09-17 arXiv preprint arXiv:2609.20095 internet-of-agentsdiscoverytrustarchitecture

The Internet of Agents is expected to enable large numbers of autonomous agents to discover, verify, and collaborate with each other across heterogeneous platforms. However, current agent protocols mainly address tool invocation and inter-agent communication, leaving scalable agent registration, trustworthy identification, and capability-oriented discovery largely unresolved. To address this, this paper proposes a scalable trust discovery architecture for the Internet of Agents. The proposed architecture adopts a hierarchical and distributed design consisting of three layers: Agent Root for trusted registry governance, Agent Registry for agent registration and metadata publication, and Agent Resolver for distributed capability discovery and trust-aware resolution. The architecture further introduces a registry-suffix-anchored composite identity scheme, which binds an agent native identifier to a trusted registry suffix to generate a globally discoverable identity. It also incorporates a dual-certificate and multi-level authentication mechanism to strengthen identity trust among agents. We implement a prototype and evaluate it through large-scale agent registration and resolution experiments. The prototype achieves an average registration latency of 58ms and an average discovery latency of 25ms, and it supports more than 19,000 registration requests per second and more than 29,000 agent discovery requests per second. These results demonstrate the feasibility of the proposed architecture, providing a practical approach toward scalable and identity-trusted agent ecosystems in the Internet of Agents.

Agent Identity Trust Framework: from static identity management to continuous trust management ↗ 详情

Joint industry bodies (reported by People's Daily online)

Report 2026 2026-09-11 Industry report, reported 2026-09-11 identity-trustcontinuous-trustagent-governanceresponsibilityreport

An industry report argued publicly on 11 September 2026 that agent identity governance must shift from static identity management to continuous trust management: issuing an identity card is not enough, because the system must keep judging at every action who the agent is, whom it belongs to, what it is authorized to do and whether it is currently trustworthy. The report splits identity into three layers — product identity (what it is), runtime identity (which instance is running) and accountable-principal identity (whom it acts for) — and combines four signal classes covering identity, environment, behaviour and task context to produce a continuously updated trust state that adjusts with risk. The accompanying reporting cites CAICT Tier Terminal Laboratory figures: fewer than 5 percent of applications embedded AI agents in 2025 against an expected 40 percent in 2026; the fastest successful attack on an agent took only 27 seconds and the average 29 minutes, while traditional security teams respond in hours. Industry bodies further forecast that by 2028, 90 percent of B2B procurement will be intermediated by AI agents, moving more than 15 trillion US dollars of B2B spend through agent trading platforms.

Report 2026 2026-09-30 Gartner press release, Stamford, 2026-09-30; underlying research The Cybersecurity Executive Outlook, 4Q26 Gartneragent-governanceagent-accessguardian-agentsagent-identitypost-quantum

Gartner press release of 30 September 2026 identifying five actions CISOs should take by the end of 2026, with two directly relevant to agent identity and access control. Verbatim: "Fifty-four percent of organizations have no defined approach to limit AI agent access, or rely on predefined human access, according to a Gartner survey in 297 cybersecurity leaders in the second quarter of 2026." Verbatim recommendation: "CISOs should govern autonomous multiagent systems based on action privileges rather than model intelligence and safeguard agentic workflows using guardian agents to constrain blast radiuses." The other four actions, also quoted: "Cement Role and Authority in AI Safety" (securing AI infrastructure and understanding the interaction between models and harnesses is more important than the safety of the model itself); "Replace Recognition as Proof of Identity" (discard recognition as an acceptable basis for decision or action authorization, augmenting deepfake detection with contextual signals, additional authentication layers and content-provenance checks); "Budget for Preemptive Cybersecurity Capabilities" (76% of CISOs ranked AI-driven discovery of cyber vulnerabilities among their top 10 emerging risks in a survey of over 300 enterprise risk leaders in Q2 2026); and "Begin Piloting Postquantum Cryptographic Migration" (organizations that do not begin piloting PQC by 2027 will face at least 200% higher full-migration costs; 51% of surveyed CISOs had not begun any PQC-related activity).

China first open-source agent interconnection protocol family aligned with the national standard series Artificial Intelligence — Agent Interconnection (GB/Z 185 / AIP), developed by Beijing University of Posts and Telecommunications and adopted by the China Electronics Standardization Institute as the basis of the AIP national-standard open-source community. Licensed under the Mulan PSL, so enterprises may build commercial versions free of charge. The family is organized into four modules: identity and trust, capability catalogue, task flow, and runtime observability, with a "layered multi-centre" architecture in which each autonomous domain runs its own registry, credential-management and discovery servers, and domains interoperate through inter-domain management nodes, yielding macro-level decentralization while preserving each party autonomy. Security rests on AIC (an OID-based agent identity code), mTLS for mutual certificate verification, and Ed25519 signatures. The v2.2.0 release (August 2026) adds the AMP monitoring protocol (six log classes; a monitor-server consuming Kafka audit topics with signature verification and chained hashing), the AAC access-control specification unifying subject expressions across humans, agents and service accounts, OIDC-based user-to-agent identity binding with delegation chains, strengthened senderId/AIC consistency checks in streaming and notification modes, Ed25519 as the default algorithm, an aliveMap liveness view in discovery, and Ansible-based image/host deployment with independent day-2 operations playbooks. Design philosophy is functional abstraction rather than entity binding, letting vendors choose centralized, layered or distributed implementations.

A telecommunications industry standard approved in September 2026 at the 43rd working group meeting of CCSA TC1WG5 and led by CAICT. It targets the production and operation of intelligent information services and applies to intelligent-computing infrastructure, AI platforms, model services, agent services, and supporting systems such as knowledge bases and tool services; it can be used both for capability building and assessment by providers and as a reference for procurement, project acceptance and supplier management. Requirements are organized around operational safety governance, monitoring and observability, capacity and performance assurance, stability protection, change and configuration management, fault and emergency assurance, disaster recovery and business continuity, external dependency and supply chain assurance, and service quality and continuous improvement, with three capability levels (basic, enhanced, advanced). The motivation is the long and tightly coupled service chain from computing resources through model inference and knowledge retrieval to agent orchestration and tool invocation, which is prone to timeouts, performance swings, task failures and cascading faults while monitoring metrics and stability guarantees remain inconsistent across the industry. CAICT scheduled the first workshop for 17 September 2026.

A group standard formally launched on 9 September 2026 at the "Safety Coordinates and Responsibility Boundaries in the Agent Era" forum of the 2026 Inclusion Bund Summit, proposed by the Cyber Security Association of China and drafted by Ant Group together with research institutes, carriers and Internet companies. It addresses the questions of who the agent is, whom it represents and what it may do. The framework builds a multi-layer trusted identity chain among agent, user and runtime environment, issues each agent a unique, trustworthy and continuously verifiable digital identity, and introduces task-intent-based dynamic access control: following least privilege, permissions activate with the task and are reclaimed promptly when the task ends, reducing over-authorization and privilege abuse. It pairs with the "Technical Requirements for Agent Runtime Security" launched the same day.

A group standard formally launched on 9 September 2026, proposed by the Cyber Security Association of China and drafted by Ant Group with research institutes, carriers and Internet companies. It focuses on what an agent actually did during execution, whether it deviated from the task, and how risk is remediated in time. Requirements span risk monitoring and control, risk detection and decision, central analysis, and performance and stability, running through the whole chain of user intent, agent planning, tool invocation, system execution and result delivery. Through layered detection and defence in depth, a single unauthorized call, an abnormal chain or a single intent deviation can each be identified, assessed and handled. It forms the runtime half of the "authenticate identity, read intent, guard runtime" baseline, complementing the identity and authorization framework launched the same day, and corresponds directly to the runtime governance duties of an agent gateway.

Introduction AI-agent discovery is being explored in several DAWN documents. The DAWN use-case work describes scenarios in which clients need to discover AI resources and obtain information required for subsequent interaction. Other DAWN contributions examine gaps in existing discovery protocols, identify information that may need to be discoverable, describe local discovery using mDNS/DNS-SD, and propose broader discovery architectures and frameworks. This document complements those efforts by focusing on managed enterprise, cloud, edge-computing, and communication- Dunbar, et al. Expires Dec 16, 2027 [Page 3] Internet-Draft Infrastructure Assisted Discovery network deployments in which infrastructure already maintains information that can assist AI-agent discovery. In such environments, orchestration, placement, hosting, gateway, or management systems can provide current information about which AI-agent services or instances are available and how they can be reached. Separately, network infrastructure can provide an abstract "Attachment Scope" representing the requester's current network applicability context. This document defines two infrastructure integration points: o a "Resource Publication Hook", through which authorized deployment infrastructure makes current AI-agent service or instance information available to the discovery mechanism; and o an "Attachment Context Hook", through which trusted network infrastructure provides the requester's current Attachment Scope. The discovery mechanism combines these infrastructure- provided inputs with requester-supplied discovery criteria and relevant agent metadata to identify AI-agent resources applicable to the request. The proposed hooks are intended to assist existing discovery mechanisms rather than replace them. For example, the local discovery approach described in [DAWN-MDNS] reuses mDNS and DNS-SD for AI-agent discovery. The infrastructure-assisted model described here follows the same principle of reusing existing discovery mechanisms, while adding support for managed deployments in which agent deployment state and requester network context are maintained by infrastructure. The model can similarly complement DNS-AID [DNS-AID] in managed environments by using infrastructure-maintained deployment state and network-derived Attachment Scope without changing the DNS-AID wire format. More generally, the Resource Publication Hook and Attachment Context Hook can provide infrastructure-facing inputs to broader DAWN discovery architectures, such as those described in [DAWN-FRAMEWORK], without requiring those architectures to depend on a particular access, cloud, or mobile-network technology. Dunbar, et al. Expires Dec 16, 2027 [Page 4] Internet-Draft Infrastructure Assisted Discovery The infrastructure assistance described in this document uses authorized control-plane or management information. It does not require infrastructure to inspect, intercept, or participate in agent-to-agent communications. This document does not define a new wire protocol. The model can be applied to DNS-SD, DNS-AID, registries, directories, federated discovery systems, or other AI-agent discovery mechanisms. 2. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. The following acronyms and terms are used in this document: AI Agent: A software entity that uses artificial intelligence techniques to interpret context, make decisions, and take actions toward achieving one or more goals, possibly by interacting with users and by invoking other agents, tools, or services. Attachment Context Hook: An infrastructure integration point through which trusted network infrastructure provides the requester's current Attachment Scope to the discovery mechanism. Attachment Scope: An abstract network-derived context representing an attachment or reachability domain applicable to a requester or discoverable resource. Discovery Mechanism: A mechanism that receives discovery intent and returns one or more applicable AI- agent resources. The mechanism may use DNS-SD, Dunbar, et al. Expires Dec 16, 2027 [Page 5] Internet-Draft Infrastructure Assisted Discovery DNS-AID, a registry, a directory, a federated discovery system, or another technique. Logical AI-Agent Service: An AI-agent service whose functional identity can remain stable while the number, location, or endpoints of its runtime instances change. Requester: An entity initiating an AI-agent discovery operation. The requester may itself be an AI agent or another application acting on behalf of one. Resource Publication Hook: An infrastructure integration point through which an authorized orchestration, placement, hosting, gateway, or management system makes current AI-agent service or instance information available to the discovery mechanism. 3. Problem Statement AI agents are increasingly deployed as software services in enterprise networks, cloud environments, edge-computing platforms, and communication networks. An AI agent may provide functions such as reasoning, information retrieval, translation, content generation, task execution, or interaction with external tools and services. Although AI agents may use conventional cloud-native deployment techniques, their interaction model can be more heterogeneous than that of many traditional software services. A conventional service is often accessed through a known API or interface contract once its endpoint is located. Different AI agents, however, may support different communication protocols, invocation methods, request or response schemas, authentication procedures, supported modalities, tools, task formats, or agent-specific parameters. A2A provides one example. An A2A Agent Card can describe an agent's identity, supported interfaces, capabilities, skills, security information, and other properties required for interaction. Therefore, locating an AI-agent endpoint and Dunbar, et al. Expires Dec 16, 2027 [Page 6] Internet-Draft Infrastructure Assisted Discovery understanding how to interact with that agent can be separate operations. This creates an opportunity to use a lightweight discovery stage to identify an applicable AI-agent service or instance and then retrieve richer agent metadata through a subsequent agent-specific mechanism. In managed deployments, information relevant to the lightweight discovery stage may be distributed among several infrastructure systems. For example, an orchestration, placement, or hosting system may know: - which AI-agent services or instances currently exist; - where an instance is deployed; - which externally reachable endpoint corresponds to that instance; - whether multiple instances share a common service endpoint; - when an instance is moved or replaced; and - when an instance is withdrawn. The AI-agent application itself need not maintain complete knowledge of this deployment state, particularly when it operates behind a load balancer, service mesh, reverse proxy, gateway, or other hosting infrastructure. Network infrastructure may separately possess information useful for determining which AI-agent resources are applicable to a requester. Such information can include: - access-network attachment; - enterprise or tenant context; - VPN or routing context; - DNN; - network slice; Dunbar, et al. Expires Dec 16, 2027 [Page 7] Internet-Draft Infrastructure Assisted Discovery - serving UPF or UPF group; - edge-computing domain; or - another reachability-related network context. Requiring the requester to understand and explicitly include such network information can couple application-layer discovery to network-specific technologies. Conversely, exposing detailed network topology or low-level identifiers directly through an AI-agent discovery mechanism can create unnecessary complexity and information exposure. Deployment information and rich agent metadata may also change at different rates. For example, an image-analysis agent may move from one edge location to another while retaining the same skills, interfaces, authentication model, and Agent Card. Changes to deployment location or endpoint do not necessarily require changes to the agent's functional metadata, such as its capabilities, skills, supported interfaces, or Agent Card. There is therefore value in separating: - information describing what an AI agent is and how it can be used; - information describing where currently deployed instances can be reached; and - information describing the requester's current attachment or reachability context. There is therefore a need to combine requester-provided discovery criteria and relevant agent metadata with current deployment information and network-derived Attachment Scope, without requiring the requester to understand network specific attachment details. The infrastructure-assisted discovery model described in this document addresses this problem by allowing deployment and network infrastructure to contribute this information to the discovery process. Dunbar, et al. Expires Dec 16, 2027 [Page 8] Internet-Draft Infrastructure Assisted Discovery 4. Gap Analysis: DNS-SD and AI-Agent Discovery DNS-Based Service Discovery [RFC6763] provides a well- established mechanism for discovering instances of a particular service type within a discovery domain. A client identifies a service type and domain and obtains service instances. SRV records identify where an instance can be reached, while TXT records may provide a small amount of additional service-specific information. This model provides a useful foundation for AI-agent discovery. draft-jakab-dawn-agent-discovery-mdns applies this approach to local AI-agent discovery and describes a two-stage model in which DNS-SD performs lightweight enumeration and the agent's native protocol subsequently provides the complete agent description. The model described in this document is compatible with that two-stage approach. However, DNS-SD by itself does not address several deployment conditions relevant to managed AI- agent environments. 4.1. Service Type Limitations For many conventional services, knowing the service type, host, port, and protocol can be sufficient to initiate application-level communication. AI-agent interaction may require additional information before meaningful interaction can begin. For example, an A2A requester may need to obtain an Agent Card describing: o supported interfaces; o skills; o capabilities; o security requirements; o interaction characteristics; and o other agent-specific information. Dunbar, et al. Expires Dec 16, 2027 [Page 9] Internet-Draft Infrastructure Assisted Discovery Trying to represent all such information in DNS-SD TXT records would duplicate metadata that is already available through the agent's native description mechanism and could make the discovery layer unnecessarily complex. A more practical approach in some deployments is to use lightweight discovery to identify an applicable agent instance or endpoint, and then retrieve richer agent-native metadata only when needed before interaction: Lightweight discovery | v Agent instance / endpoint | v Retrieve agent-native metadata | v Interaction 4.2. External Deployment State Traditional DNS-SD commonly assumes that a service or the system hosting it registers the appropriate service-discovery information. Managed AI-agent environments may involve additional deployment abstraction. For example, an orchestration system can create several runtime instances of the same logical A2A service: Vision Agent Service | +-----------+-----------+ | | | v v v Instance-A Instance-B Instance-C The instances may share the same Agent Card and capabilities while having different endpoints or attachment contexts. Alternatively, the three instances may sit behind one stable service endpoint: Dunbar, et al. Expires Dec 16, 2027 [Page 10] Internet-Draft Infrastructure Assisted Discovery Vision Agent Service | Common Endpoint | +--------+--------+ | | | A B C In this case, changes to the backend instances need not change agent metadata or the externally published discovery endpoint. A discovery architecture therefore benefits from distinguishing the logical AI-agent service from currently deployed instances. 4.3. Discovery Domain vs. Network Scope DNS-SD uses a discovery domain to determine where service enumeration occurs. In a managed communication network, however, the set of agent instances applicable to a requester may depend on a network context that is different from a DNS administrative domain. For example, two requesters using the same DNS namespace may be associated with: o different enterprise VPNs; o different DNNs; o different network slices; o different UPFs; o different edge domains; or o different tenant contexts. Those requesters may therefore have access to different edge- resident AI-agent instances even though they query the same general service category. Conversely, several underlying network states may belong to the same discovery applicability domain. For example: Dunbar, et al. Expires Dec 16, 2027 [Page 11] Internet-Draft Infrastructure Assisted Discovery UPF-A + DNN-X + Slice-1 ----+ | UPF-B + DNN-X + Slice-1 ----+--> Attachment Scope X | VPN-X + Enterprise-A -------+ DNS-SD does not itself define such a mapping between requester-side network state and discovery applicability. 4.4. Hidden Network Context A requester can reasonably know what type of AI-agent service it seeks. For example: Service-Category: Vision-Inference It should not necessarily need to know: Serving-UPF DNN S-NSSAI VRF BNG Access Circuit Edge Domain Those properties belong to the infrastructure. Requiring an AI-agent application to understand them creates unnecessary coupling between application discovery and network architecture. 4.5. Discovery vs. Selection Existing service-discovery and service-routing systems often use region, zone, or locality information to steer a request toward a preferred instance. The Attachment Scope described in this document serves a different initial purpose. It identifies the network context within which an AI-agent resource is applicable to a requester. Dunbar, et al. Expires Dec 16, 2027 [Page 12] Internet-Draft Infrastructure Assisted Discovery For example: Requester Intent: Vision-Inference Attachment Scope: AScope-A Published Instances: Agent-A -> AScope-A Agent-B -> AScope-B Agent-C -> Shared-Cloud The discovery mechanism may determine that Agent-A and Agent- C are applicable. A later selection mechanism can choose between them based on latency, load, cost, GPU availability, or another dynamic factor. Thus: Discovery: Which resources are applicable? Selection: Which applicable resource should be used? The two functions are intentionally separated. 5. Infrastructure-Assisted Discovery Model The infrastructure-assisted discovery model combines information from the requester, deployment infrastructure, network infrastructure, and the discovery mechanism. The purpose of the model is to allow infrastructure that already maintains deployment and network state to contribute that information to AI-agent discovery, without requiring the requesting AI agent to understand the underlying deployment or network-specific details. The model uses three primary categories of information: Requester Discovery Criteria Dunbar, et al. Expires Dec 16, 2027 [Page 13] Internet-Draft Infrastructure Assisted Discovery + Published AI-Agent Resource State + Requester Attachment Scope | v Discovery Mechanism | v Applicable AI-Agent Resources 5.1. Requester Criteria The requester provides information describing what it wants to discover. The request may identify: - a specific AI-agent resource; - an AI-agent service category; - a subtype; - a supported interaction protocol; - a capability or skill; - or other agent-related discovery criteria supported by the discovery mechanism. The requester is not required to provide network-specific information such as a serving UPF, DNN, network slice, VPN, access point, or edge domain. 5.2. Published Resource State Deployment infrastructure provides information describing the AI-agent resources currently available for discovery. This information can include: o logical service identifier; o instance identifier; o reachable endpoint; o communication protocol; o current deployment state; o Attachment Scope associated with the resource, when applicable; and o a reference to additional agent metadata. Dunbar, et al. Expires Dec 16, 2027 [Page 14] Internet-Draft Infrastructure Assisted Discovery The Resource Publication Hook described in Section 6 provides this information to the discovery mechanism. The published resource may represent either: o a logical AI-agent service exposed through a stable endpoint; or o an individually reachable runtime instance. The choice depends on how the AI-agent service is deployed and exposed. Deployment infrastructure is responsible for keeping this information consistent with the actual deployment state. 5.3. Requester Scope Trusted network infrastructure determines the requester's current Attachment Scope from network attachment or reachability state. The Attachment Scope abstracts network-specific information such as: o access attachment; o VPN or routing context; o DNN; o network slice; o serving UPF; o tenant context; or o edge domain. The Attachment Context Hook described in Section 7 provides the resulting Attachment Scope to the discovery mechanism. Dunbar, et al. Expires Dec 16, 2027 [Page 15] Internet-Draft Infrastructure Assisted Discovery The Attachment Scope is infrastructure-provided context. It is not required to be supplied by the requester and does not need to be exposed to the requester. 5.4. Discovery Processing The discovery mechanism combines requester discovery criteria with current published resource state and the requester's Attachment Scope. The mechanism can also use agent metadata that it maintains, indexes, or references. Conceptually: Agent Metadata | v Requester Intent --> Candidate Identification | v Candidate Resources | +------------------+ | | v | Attachment Scope | | | +--------+---------+ | v Applicability Processing | v Applicable Resources Agent-related criteria determine which resources can satisfy the requester's functional intent. Attachment Scope determines which of those candidate resources are applicable from the requester's current network context. These two functions are complementary. Dunbar, et al. Expires Dec 16, 2027 [Page 16] Internet-Draft Infrastructure Assisted Discovery 5.5. Metadata and Deployment State Agent metadata and deployment state describe different properties and can change independently. For example, an A2A Agent Card can describe an agent's capabilities, skills, supported interfaces, and security requirements. The same logical agent service can be deployed at several locations or moved between locations without changing those properties. Conversely, deployment infrastructure can update an endpoint, instance identifier, or associated Attachment Scope without requiring the underlying functional description of the agent to change. The discovery mechanism may maintain or reference both kinds of information, but they need not be represented or updated in the same way. 5.6. Applicability Versus Selection The result of infrastructure-assisted discovery is a set of AI-agent resources that are applicable to the requester. The discovery mechanism does not necessarily select the optimal resource from that set. For example, discovery may determine that two AI-agent instances are both applicable: Agent-A Agent-B A subsequent selection function can choose between them based on factors such as latency, network condition, compute load, accelerator availability, cost, or application policy. The distinction between discovery applicability and resource selection is described further in Section 11. 5.7. Relationship to Specific Discovery Mechanisms The infrastructure-assisted model is independent of a particular discovery protocol. Dunbar, et al. Expires Dec 16, 2027 [Page 17] Internet-Draft Infrastructure Assisted Discovery The Resource Publication Hook and Attachment Context Hook provide inputs to the discovery process, while the underlying discovery mechanism can use DNS-SD, DNS-AID, a registry, a directory, a federated discovery system, or another mechanism. Section 8 and 9 describe how the model can be realized using DNS-SD and DNS-AID respectively. The model does not require changes to agent-to-agent communication protocols and does not require infrastructure to inspect the contents of agent communications. 6. Resource Publication and Update The Resource Publication Hook allows deployment infrastructure to maintain information about AI-agent resources currently available for discovery. The procedure can be illustrated using an A2A deployment. An A2A Agent Card describes the agent's interaction-related characteristics. The Resource Publication Hook instead describes current deployment and reachability state. For example: Logical-Service-Identifier: Vision-Inference Instance-Identifier: Vision-Agent-A Service-Category: Vision-Inference Endpoint: https://vision-a.edge.example Attachment-Scope: AScope-A Protocol: A2A Agent-Card-Reference: https://vision-a.edge.example/.well-known/agent-card.json 6.1. Logical Service vs. Instance Publication Where multiple runtime instances share a stable service endpoint: Document-Analysis-Agent | v Stable Service Endpoint Dunbar, et al. Expires Dec 16, 2027 [Page 18] Internet-Draft Infrastructure Assisted Discovery | +----+----+----+ | | | | A B C D the discovery mechanism may publish only: Logical-Service-Identifier: Document-Analysis-Agent Endpoint: https://document-agent.example Protocol: A2A Agent-Card-Reference: https://document-agent.example/.well-known/agent- card.json Scaling from four instances to eight need not modify the discovery publication. If the instances are independently reachable or have different Attachment Scopes, they may instead be published individually. 6.2. Cloud Deployment Example An A2A agent hosted on a Kubernetes-based cloud platform may be exposed through a Kubernetes Service, ingress gateway, or externally assigned endpoint. When the common endpoint remains stable, backend Pod creation or removal need not affect discovery. If the externally visible endpoint changes because the service is moved to another cluster: Before: Endpoint: cluster-a.example/agent After: Endpoint: cluster-b.example/agent the orchestration infrastructure can update the publication while the Agent Card remains unchanged. Dunbar, et al. Expires Dec 16, 2027 [Page 19] Internet-Draft Infrastructure Assisted Discovery 6.3. 5G Edge Deployment Example Consider two runtime instances of the same logical AI-agent service: Edge Orchestrator / \ v v Edge-A Edge-B Agent-A Agent-B | | UPF-A UPF-B The publications may be: Agent-A Logical-Service: Vision-Inference Endpoint: vision-a.edge.example Attachment-Scope: AScope-A and: Agent-B Logical-Service: Vision-Inference Endpoint: vision-b.edge.example Attachment-Scope: AScope-B If Agent-A moves to another edge environment, the infrastructure can change its endpoint and scope or withdraw the old instance and publish a new one. 6.4. Publication Lifecycle Publication events can include: - initial deployment; - new instance creation; - endpoint assignment; - scale-out or scale-in; - migration; - gateway change; - Attachment Scope change; - failure or unavailability; and - withdrawal. Dunbar, et al. Expires Dec 16, 2027 [Page 20] Internet-Draft Infrastructure Assisted Discovery The publication mechanism may be event-driven, controller- driven, registry-based, DNS-based, or implemented through another infrastructure interface. 7. Attachment Scope Determination and Update Attachment Scope abstracts network state that is relevant to discovery applicability. The network may derive Attachment Scope from one or more constructs, including: - access network; - cell or tracking area; - serving UPF or UPF group; - DNN; - network slice; - VPN or VRF; - enterprise or tenant context; - edge domain; or - other network reachability state. For example: UPF: UPF-A DNN: enterprise-ai Slice: Slice-1 Enterprise: Enterprise-A | v Attachment-Scope: AScope-A The discovery mechanism does not need to understand how AScope-A was derived. 7.1. Policy-Based Mapping The mapping can be many-to-one: UPF-A + DNN-X ----+ | UPF-B + DNN-X ----+--> AScope-X | Dunbar, et al. Expires Dec 16, 2027 [Page 21] Internet-Draft Infrastructure Assisted Discovery VPN-X ------------+ This enables a deployment to define discovery applicability independently of a particular network technology. 7.2. Requester Attachment Scope A requester may issue a discovery request such as: Service-Category: Vision-Inference Separately, network infrastructure determines the requester's current Attachment Scope based on network attachment state and provides it to the discovery mechanism: Attachment-Scope: AScope-A The discovery mechanism combines the requester's discovery criteria with the network-provided Attachment Scope when determining applicable AI-agent resources. The requester therefore does not need to know or supply network-specific information such as its serving UPF, network slice, DNN, VPN, or edge-domain association. 7.3. Scope Policy Attachment Scope matching does not require the requester and resource to have identical scope values. A deployment may define policy that determines which resource Attachment Scopes are applicable to a requester's Attachment Scope. For example, a requester associated with AScope-Edge-A may be permitted to discover resources published for the same edge scope, a broader metropolitan scope, or a shared cloud scope: Requester Attachment Scope: AScope-Edge-A Applicable Resource Scopes: AScope-Edge-A AScope-Metro AScope-Shared-Cloud Dunbar, et al. Expires Dec 16, 2027 [Page 22] Internet-Draft Infrastructure Assisted Discovery Such policy allows discovery applicability to reflect deployment relationships among edge, regional, and shared resources without exposing the underlying network-specific information used to derive the requester's Attachment Scope. 7.4. Mobility and Reassociation Attachment Scope can change when the requester: - moves between access areas; - changes serving UPF; - changes DNN; - changes slice; - moves between VPN or tenant contexts; - moves between Wi-Fi and cellular access; or - enters another edge domain. For example: Before: UPF-A -> AScope-A After reassociation: UPF-B -> AScope-B Subsequent discovery can therefore return resources applicable to the requester's new network context. Attachment Scope may be updated through events, queried at discovery time, or cached with an appropriate validity period. 8. Applying the Model to DNS-SD This section describes how the infrastructure-assisted discovery model in Section 5 can be realized using DNS-SD [RFC6763]. The general roles of requester criteria, published resource state, Attachment Scope, and discovery processing are defined in Section 5 and are not repeated here. Dunbar, et al. Expires Dec 16, 2027 [Page 23] Internet-Draft Infrastructure Assisted Discovery In the DNS-SD realization, the Resource Publication Hook maps current AI-agent resource state into DNS-SD service information, while the Attachment Context Hook provides network-derived context used to determine which DNS-SD discovery domains or service instances are applicable to the requester. No change to the DNS-SD query or response protocol is required by this document. 8.1. DNS-SD Mapping DNS-SD [RFC6763] represents service discovery using service types, instance enumeration, and endpoint resolution. The infrastructure-assisted model maps onto those mechanisms as follows: Published AI-Agent Resource State | v DNS-SD Representation PTR -> discoverable service instances SRV -> reachable target and port TXT -> selected discovery attributes or references to agent metadata For example, an AI-agent instance may be represented as: Vision-Agent-A._example-agent._tcp.example.com. with an SRV record identifying: vision-a.edge.example.com.:443 and TXT information such as: protocol=A2A metadata= https://vision-a.edge.example.com/.well-known/agent- card.json Dunbar, et al. Expires Dec 16, 2027 [Page 24] Internet-Draft Infrastructure Assisted Discovery The service type, instance naming convention, and TXT attributes shown above are illustrative. This document does not define a new DNS-SD service type or new TXT keys. 8.2. DNS-SD Publication When DNS-SD is used, the Resource Publication Hook described in Section 6 can populate and update the DNS-SD representation of currently available AI-agent resources. The deployment or orchestration system provides the information needed to create, update, or withdraw the corresponding DNS-SD records as the published AI-agent resource state changes. Conceptually: AI-Agent Deployment State | v Resource Publication Hook | +--> PTR: service-instance enumeration | +--> SRV: reachable target and port | +--> TXT: selected discovery attributes or metadata reference A published resource may represent either a logical AI-agent service or an individually reachable instance, as described in Section 6.1. When a published endpoint changes, the corresponding SRV information can be updated without requiring unrelated agent metadata to change. When a published resource is no longer available, its corresponding DNS-SD information can be withdrawn. An authorized controller may populate and maintain these records on behalf of the AI-agent service. Where Dynamic DNS is used, DNS UPDATE [RFC2136] can be used to add, modify, or remove DNS resource records. Other deployments may use Dunbar, et al. Expires Dec 16, 2027 [Page 25] Internet-Draft Infrastructure Assisted Discovery authoritative DNS management interfaces, orchestration APIs, or controller-specific mechanisms. The interface between the Resource Publication Hook and DNS infrastructure is outside the scope of this document. 8.3. Applying Attachment Scope The requester's Attachment Scope is provided to the discovery function through the Attachment Context Hook described in Section 7. It is not required to be carried in the DNS-SD request itself. When DNS-SD is used, Attachment Scope can be applied in at least two ways: o by mapping the requester's Attachment Scope to one or more DNS-SD discovery domains; or o by filtering enumerated resources according to the requester's Attachment Scope and deployment policy. 8.3.1. Scope to Domain Mapping A deployment can associate an Attachment Scope with one or more DNS-SD discovery domains. For example: Attachment-Scope: AScope-Edge-A | +--> edge-a.agent.example | +--> shared.agent.example A requester may issue only its application-level discovery intent, such as: Service-Category: Vision-Inference Dunbar, et al. Expires Dec 16, 2027 [Page 26] Internet-Draft Infrastructure Assisted Discovery The discovery function combines this request with the network-provided Attachment Scope and determines which DNS-SD domains are applicable. For example: Requester Intent: Vision-Inference Attachment Scope: AScope-Edge-A Applicable Discovery Domains: edge-a.agent.example shared.agent.example DNS-SD enumeration can then be performed within those domains using the procedures defined in [RFC6763]. This approach allows the DNS-SD discovery domain to reflect network applicability without requiring the requester to know which domain corresponds to its current network attachment. The mapping from Attachment Scope to discovery domains is deployment policy. 8.3.2. Filtering Resources After Enumeration Another deployment can use a common DNS-SD discovery domain that contains AI-agent resources associated with multiple Attachment Scopes. For example: Vision-Agent-A Attachment-Scope: AScope-A Vision-Agent-B Attachment-Scope: AScope-B Vision-Agent-C Dunbar, et al. Expires Dec 16, 2027 [Page 27] Internet-Draft Infrastructure Assisted Discovery Attachment-Scope: AScope-Shared The discovery function can first identify resources matching the requester's service-related criteria and then apply policy based on the requester's Attachment Scope. For a requester associated with: Attachment-Scope: AScope-A the applicable resource scopes might be: AScope-A AScope-Shared The resulting resources could therefore be: Vision-Agent-A Vision-Agent-C The Attachment Scope associated with a resource does not need to be exposed to the requester or encoded in a generally visible DNS-SD TXT record. It can instead be maintained by a trusted discovery component or associated infrastructure database. This approach is useful when resources associated with multiple network contexts share a common DNS-SD namespace, or when Attachment Scope information should remain internal to the infrastructure. In both approaches, DNS-SD continues to provide service- instance enumeration and endpoint resolution. The infrastructure-provided Attachment Scope determines which DNS-SD discovery domains or enumerated service instances are applicable to the requester's current network context. 8.4. Agent Metadata in DNS-SD Agent metadata used for discovery matching may be represented directly in DNS-SD, maintained separately by the discovery system, or obtained through a reference to an agent-native metadata mechanism. Dunbar, et al. Expires Dec 16, 2027 [Page 28] Internet-Draft Infrastructure Assisted Discovery A deployment may place selected discovery attributes in DNS- SD TXT records, such as a supported protocol or a reference to richer metadata. For example: protocol=A2A metadata= https://vision-a.edge.example/.well-known/agent- card.json Other attributes, such as skills, capabilities, supported modalities, or authentication characteristics, may be indexed by the discovery system without being encoded directly in DNS-SD. For an A2A deployment, some or all of this information may originate from an Agent Card. The complete Agent Card does not need to be duplicated in DNS-SD TXT records. The choice of which attributes are represented directly in DNS-SD and which are maintained or retrieved separately is deployment-specific. 8.5. Discovery Result The DNS-SD realization returns the service instances that remain applicable after the processing described in Section 8.3 and, where applicable, the metadata matching described in Section 8.4. For an applicable resource, DNS-SD provides the information needed to identify and resolve the published service instance. For example, the resulting information may correspond to: Resource-Identifier: Vision-Agent-A Endpoint: https://vision-a.edge.example Protocol: A2A Metadata-Reference: https://vision-a.edge.example/.well-known/agent- card.json Dunbar, et al. Expires Dec 16, 2027 [Page 29] Internet-Draft Infrastructure Assisted Discovery For DNS-SD, the target host and port are resolved using the normal SRV and address-resolution procedures defined by [RFC6763] and [RFC2782]. The Attachment Scope used to determine applicability does not need to be returned to the requester. It is infrastructure context used during discovery rather than information required for subsequent agent communication. A DNS-SD result may contain multiple applicable service instances. Where SRV records are used, the Priority and Weight procedures defined by [RFC2782] continue to apply. These procedures do not replace a separate resource-selection function when additional criteria such as network condition, compute load, accelerator availability, cost, or application policy are required. Additional agent-specific metadata, such as an A2A Agent Card, may be provided by reference or retrieved subsequently as described in Section 10. This document does not change the DNS-SD response format. 8.6. Caching and Freshness AI-agent deployment state can change after discovery information has been published. For example: o an instance can be withdrawn; o an endpoint can change; o an agent can move to another edge site; o an Attachment Scope associated with a resource can change; or o a requester can move to a different Attachment Scope. The Resource Publication Hook is responsible for reflecting changes to resource deployment state in the discovery system. Dunbar, et al. Expires Dec 16, 2027 [Page 30] Internet-Draft Infrastructure Assisted Discovery When DNS is used, normal DNS TTL semantics apply. [RFC1035] specifies the interval for which a resource record can be cached before the source of the information should be consulted again. Deployments in which agent endpoints or placement change frequently can therefore use TTL values appropriate to the expected lifetime of the published information. Very dynamic deployment information should not be treated as indefinitely valid merely because it was previously returned by discovery. Attachment Scope can have a lifetime that is independent of the lifetime of DNS resource records. For example, a requester may change from: AScope-A to AScope-B. while previously discovered DNS information remains present in a cache. A new discovery operation should therefore use the requester's current Attachment Scope rather than assuming that a previously determined Attachment Scope remains valid. Implementations should avoid treating cached resource information and cached Attachment Scope as having the same validity period unless deployment policy explicitly defines them that way. 8.7. No Match A discovery request can identify no resource that satisfies both the agent-related discovery criteria and the applicable Attachment Scope policy. For example: Requested: Vision-Inference Candidate: Agent-B -> AScope-B Dunbar, et al. Expires Dec 16, 2027 [Page 31] Internet-Draft Infrastructure Assisted Discovery Requester: AScope-A If policy does not permit AScope-A to use resources in AScope-B, the discovery result contains no applicable resource. The discovery mechanism may return an empty result or use mechanisms provided by the underlying discovery system to indicate that no applicable resource was found. A deployment can also define fallback policy. For example, when no edge-local resource is applicable, the discovery mechanism may consider an AI-agent resource published for a shared cloud Attachment Scope. Such fallback behavior is deployment policy and is not mandated by this document. 9. Applying the Model to DNS-AID DNS for AI Discovery (DNS-AID) [DNS-AID] uses existing DNS mechanisms to publish AI-agent connectivity and discovery information. For a known agent, DNS-AID uses SVCB records to provide endpoint, transport, agent-protocol, and capability- related information. When the requester knows an organization but not a specific agent, DNS-AID uses the well-known _index._agents.<domain> entry point to locate an organization-specific agent index. The infrastructure-assisted model in Section 5 can complement DNS-AID in managed enterprise, cloud, edge, and communication-network environments. The Resource Publication Hook can keep DNS-AID-visible agent information aligned with current deployment state, while the Attachment Context Hook can provide network-derived context used to determine which published agents or discovery information are applicable to a requester. The Attachment Scope is not required to be encoded in DNS-AID SVCB records or carried in DNS queries. Infrastructure Dunbar, et al. Expires Dec 16, 2027 [Page 32] Internet-Draft Infrastructure Assisted Discovery assistance is applied around the DNS-AID mechanism and does not change the DNS-AID wire format. 9.1. DNS-AID Mapping The Resource Publication Hook can map current AI-agent deployment state to the information exposed through DNS-AID. Conceptually: AI-Agent Deployment State | v Resource Publication Hook | +--> Agent SVCB record | endpoint / transport / agent protocol | capability metadata or reference | +--> Organization agent index discoverable agent inventory For a known agent, changes to an externally reachable endpoint, supported protocol, or referenced capability information can result in corresponding updates to the published DNS-AID information. When an agent is withdrawn, its published information can likewise be removed or made unavailable. For organization-level discovery, deployment or management infrastructure can keep the organization-specific agent index synchronized with the set of AI-agent services or instances that are currently intended to be discoverable. The exact format and access protocol of that index remain outside the scope of DNS-AID. 9.2. Applying Attachment Scope to DNS-AID In a managed environment, the Attachment Context Hook can provide the requester's current Attachment Scope to the Dunbar, et al. Expires Dec 16, 2027 [Page 33] Internet-Draft Infrastructure Assisted Discovery discovery function before or while DNS-AID information is used. The Attachment Scope can then be applied by deployment policy to determine which DNS-AID-published agents or organization-index results are applicable to the requester. For example, an organization may publish agents reachable from an enterprise edge environment as well as agents reachable through a shared cloud environment. A requester associated with AScope-Edge-A could be permitted to use both edge-local and shared-cloud agents, while a requester associated with another Attachment Scope could receive or use a different applicable set. A deployment can apply this policy when selecting an organization index to consult, when presenting a managed view of an organization index, or when filtering the agents obtained from that index. These are deployment choices; this document does not require Attachment Scope to be published in DNS or returned to the requester. In this way, DNS-AID continues to provide the DNS-based bootstrap and agent connectivity information, while infrastructure-provided Attachment Scope contributes requester-specific applicability information. 9.3. Relationship to DNS-AID Results Infrastructure assistance does not change the DNS-AID result format. For a known-agent lookup, the requester can use the SVCB information published by DNS-AID to locate and connect to the applicable agent. For organization-level discovery, the requester can follow the DNS-AID organization-index entry point and use the resulting index information to identify candidate agents. Where several agents satisfy the requester's criteria and Attachment Scope, the discovery result may contain multiple applicable resources. Subsequent resource selection remains separate, as described in Section 11. Dunbar, et al. Expires Dec 16, 2027 [Page 34] Internet-Draft Infrastructure Assisted Discovery 10. Second-Stage Agent Metadata Retrieval A discovery mechanism may maintain sufficient agent metadata to perform discovery matching. Once an applicable resource has been identified, the requester can retrieve additional protocol-specific information using the agent's native mechanism when needed. For A2A: Discovery Response | v Agent Card Reference | v Retrieve Agent Card | v Identity, Capabilities, Skills, Interfaces, Security, Interaction Requirements Other AI-agent protocols may use different descriptors. This model avoids requiring one general discovery mechanism to reproduce all protocol-specific agent metadata. 11. Relationship to Resource Selection Attachment Scope determines applicability rather than optimization. For example: Discovery Result: Agent-A Agent-B means that both agents are usable within the applicable discovery context. A separate mechanism may select one based on: - latency; - network congestion; Dunbar, et al. Expires Dec 16, 2027 [Page 35] Internet-Draft Infrastructure Assisted Discovery - compute load; - GPU availability; - service cost; - application policy; or - another dynamic metric. Mechanisms such as CATS may be applicable to such subsequent network-aware selection. 12. Alternative methods The infrastructure-assisted model does not depend on a particular discovery protocol. The discovery mechanism may use: - DNS-AID; - DNS-SD; - a centralized registry; - a distributed directory; - a federated discovery mechanism; or - another service-discovery system. The Resource Publication Hook may be implemented by: - Kubernetes or cloud orchestration; - serverless hosting infrastructure; - MEC orchestration; - an application gateway; - a service mesh; - an enterprise AI platform; or - another deployment controller. Attachment Scope may be derived from: - 5G network state; - enterprise VPN/VRF state; - Wi-Fi infrastructure; - cloud networking; - SD-WAN state; - edge-controller state; or - combinations of these. Dunbar, et al. Expires Dec 16, 2027 [Page 36] Internet-Draft Infrastructure Assisted Discovery Resource and Attachment Scope state may be updated through events, queried dynamically, periodically refreshed, or cached. Agent-native metadata may be represented using an A2A Agent Card, MCP metadata, another protocol-specific descriptor, or a deployment-specific format. 13. Security Considerations Attachment Scope may be derived from sensitive network information. The discovery mechanism should receive only the abstraction needed for discovery and should not require unnecessary exposure of: - subscriber identity; - physical access port; - precise geographic location; - internal topology; - routing identifiers; or - detailed network configuration. Infrastructure providing Attachment Scope needs to be trusted by the discovery mechanism. A requester should not be able to obtain unauthorized resources merely by asserting an Attachment Scope in an untrusted request. Likewise, Resource Publication Hooks need authentication and authorization so that unauthorized systems cannot publish, alter, or withdraw AI-agent resource information. Discovery information can reveal the existence and reachability of AI resources. Deployments should therefore apply appropriate visibility and access policies. 14.

B. Morrison

Standard 2026 2026-10-21 IETF Internet-Draft, Intended status: Informational (individual submission, rev -09; Alter Meridian Pty Ltd) IETF → IETFMCPagent-discoveryDNSDNSSECDANEidentity

This document defines a DNS-based mechanism for discovering Model Context Protocol (MCP) servers, the identity of the organisations that operate them, and a cryptographic identity envelope bound to an individual Sovereign-tier ~handle published under the same zone. Three TXT records are defined. _mcp.<domain> advertises an MCP server's endpoint URL, agent protocol family, transport binding, cryptographic identity, and capability profile. _org-alter.<domain> advertises the operator's canonical organisational identity, including its legal entity, registry identifier, regions of operation, and any regulatory framework under which it must refuse external automated access. _alter.<domain> publishes an Ed25519-signed envelope binding a ~handle to a public key, an IdentityLog root reference, and a revocation commitment. DNSSEC validation is REQUIRED for the envelope record, and a DANE TLSA pin on the MCP endpoint is REQUIRED where resolving an envelope and opening an MCP session are one recognition transaction. The mechanism complements HTTPS-based discovery, and follows the precedent set by DKIM, SPF, DMARC, and MTA-STS. A companion alter: URI scheme is provisionally registered with IANA.

The agent URI Scheme and Verifiable Agent Identity (draft-narvaneni-agent-uri-04) ↗ 详情

Standard 2026 2026-10-20 IETF Internet-Draft, Intended status: Standards Track (individual submission, rev -04) IETF → IETFagent-identityagent-uriDIDHTTP-message-signaturesWIMSEnaming

Software agents increasingly act on the Internet on behalf of people and organizations: they call APIs, browse websites, and delegate work to other agents. Protocols such as A2A and MCP define how agents communicate, but there is no interoperable way to answer a prior question: _which agent is this, and how can its claims be verified?_ This document defines the agent URI scheme as a stable, human-readable identifier for an agent, a deterministic mapping from that identifier to an HTTPS-hosted Agent Identity Document, anchoring of the agent's keys to a web origin or a Decentralized Identifier, and signed statements that bind the agent to its protocol metadata. It also defines profiles that let an agent prove its identity on HTTP requests, building on HTTP Message Signatures for automated traffic, and that let short-lived agent instances act under the agent's identity using the WIMSE Workload Identity Token format. It deliberately does not define how agents communicate, describe their capabilities, or are invoked.

A Framework for Agent Discovery in DAWN (draft-zhang-dawn-agent-discovery-framework-01) ↗ 详情

Bin Zhang

Standard 2026 2026-09-07 IETF Internet-Draft (individual, DAWN) IETF · dinrg → IETFDAWNagent-discoveryfederationdata-sovereigntyarchitecture

A 31-page individual Internet-Draft proposing a two-layer federated reference architecture for cross-organizational AI agent discovery within the IETF DAWN work. The Local Discovery Plane performs zero-configuration agent advertisement and collection inside a site without mandating a link-local protocol; the Federation Plane links site gateways that already trust each other through lightweight Federation Metadata Records (FMR), a concrete binding of the DAWN Minimum Discoverable Information, while full Capability Cards are fetched on demand over authenticated unicast. Data sovereignty is enforced by an Export Policy Engine in the site gateway, which decides which records reach which peers and which fields are stripped, so one local inventory yields different subsets per peer. The draft is Informational, defines no normative protocol formats and does not compete with ACAP, Agent Directory or ARDP. Note a known gap raised in public review: the FMR carries origin, endpoint, capability, freshness and provenance but no authorized-audience set, redistribution flag or export-policy version, so the origin sharing decision does not travel with the record beyond the first hop.

Federated Agent Metadata Synchronization Protocol (FAMS-P) ↗ 详情

Standard 2026 2026-10-14 IETF Internet-Draft draft-zhang-dawn-bgp-style-federated-discovery-00 (DAWN) IETF → IETFDAWNagent-discoveryagent-registryfederationBGProutingprotocol

This document specifies the Federated Agent Metadata Synchronization Protocol (FAMS-P), a normative protocol realization of the "BGP-like structured peering" federation mode (Mode B) defined in the two-layer DAWN discovery architecture (draft-zhang-dawn-agent-discovery-framework). FAMS-P is a peer-to-peer unicast protocol for synchronizing agent discovery metadata between Federation Gateways (FGWs) across administrative domains, in deployments where the preferred DNS delegation model does not meet operational requirements, such as closed trusted federations of approximately 2 to 200 sites. FAMS-P runs over mutually-authenticated TLS 1.3 sessions between peering gateways. It supports initial full metadata synchronization and incremental updates for agent online, offline, and change events. Each gateway maintains a local Federated Agent Directory (FAD). The protocol synchronizes only lightweight Federation Metadata Records (FMRs) — a concrete binding of the DAWN Minimum Discoverable Information (MDI) — and thus transfers only the minimum public discovery information permitted by the DAWN charter; richer capability retrieval is out of scope. The protocol defines complete message formats, a session state machine with connection collision resolution, timestamp-and-replay- protected conflict resolution, mandatory FMR origin signatures, time-to-live aging with bounded refresh jitter, and fine-grained per-peer export policy enforcement.

A Framework for Network- and Compute-Aware Cross-Domain Agentic Systems (draft-zhao-rtgwg-agentic-systems-00) ↗ 详情

D. Zhao, Q. Li, Y. Wang, C. Jiang

Standard 2026 2026-10-21 IETF Internet-Draft, Intended status: Informational (individual submission to RTGWG, rev -00; Pengcheng Laboratory) IETF → IETFRTGWGagent-networkroutingcompute-awarecross-domainarchitecture

Agentic systems can carry out tasks using agents, model services, data services, tools, and computing environments distributed across sites and administrative domains. Dependencies among these components create communication and computing requirements that may evolve during execution. Whether a proposed collaboration can satisfy those requirements depends on network connectivity and performance, computing capacity and readiness, data and model locality, and the policies governing resource use and data movement. This document describes a framework for cross-domain agentic collaboration that accounts for task dependencies and the network and computing conditions affecting communication and execution. It outlines the roles and interactions of agents and their runtimes, infrastructure information functions, and resource-management functions. The framework relates task dependencies to communication and computing requirements, with consideration of execution locations, data movement, and constraints spanning dependent activities. It discusses the use of appropriately scoped domain information to assess alternative combinations of agents, services, and tools, together with the abstraction and updating of that information under partial visibility and independent domain policies. The framework also addresses adaptation to evolving dependencies and infrastructure conditions, including information overhead and the stability of decisions in large agent populations.

Agent Communication Protocols (agentproto) — proposed IETF Working Group charter (charter-ietf-agentproto-00-04) ↗ 详情

IETF (responsible AD: Charles Eckel), agentproto Working Group

Standard 2026 2026-10-02 IETF proposed Working Group charter (charter-ietf-agentproto-00-04); on the IESG telechat agenda of 2026-10-08 IETF → IETFagentprotoagent-dialogworking-groupcharterMCPA2ASCITTWIMSE

Proposed IETF Working Group charter "Agent Communication Protocols (agentproto)", revision charter-ietf-agentproto-00-04, status "External Review", WG state "Proposed", responsible AD Charles Eckel, listed on the IESG telechat agenda of 2026-10-08. Verbatim from the charter: "The scope of Agent Communication Protocols (agentproto) Working Group is to define a common baseline agentic dialog management protocol and build a reference architecture to integrate related protocol building blocks, enabling interoperability across platforms and vendors." A dialog is defined as "the correlated sequence of interactions between two or more participants over the course of a task", and dialog context as "the identifiers and lifecycle state needed to correlate and maintain an agentic dialog. It does not include the content exchanged with AI models, such as conversation memory, retrieved documents, or prompts." Verbatim: "The agentic dialog management protocol neither replaces application-layer agent communication protocols nor defines a new transport protocol. It defines dialog identifiers, lifecycle semantics, and the propagation of dialog context, together with bindings specifying how that context is carried over existing IETF protocols." Deliverables: an Agentic Dialog Management Protocol (Standards Track) defining dialog management primitives (correlation across multiple hops and trust boundaries; establishment, modification, termination and revocation of propagation relationships; recovery and unreachability handling) and transport bindings over existing IETF protocols such as HTTP, QUIC, WebTransport, WebRTC or MoQ; plus a Reference Architecture (Informational) and Use Cases and Requirements (Informational). Verbatim: "The dialog context is defined so that existing application-layer agent communication protocols (e.g., the Model Context Protocol (MCP) and the Agent2Agent (A2A) protocol) can carry it using their own mechanisms." Key consideration quoted: "AI agents act as autonomous software entities that may need to be authenticated independently of the users who delegated authority to them." Out of scope: agent implementation details, standardization of agent decision-making or planning semantics, agent behavioral security, human-to-agent UX, and audit data structures. Proposed milestones: adopt an informational use-cases draft by December 2026, an informational architecture draft by February 2027, adopt a proposed-standard dialog management protocol draft by March 2027, and submit it to the IESG as a proposed standard by March 2028.

Verbatim from the IETF BoF request page (Description, retrieved 2026-10-12): "Autonomous and semi-autonomous software agents are increasingly acting on behalf of users across multiple services and administrative domains. These agents interact across multiple administrative or trust domains and can initiate actions without direct human oversight at each step. The increased use of complex agent communications introduces significant challenges for auditability, accountability, transparency. Existing mechanisms, such as system logs, tracing systems, and authorization frameworks, capture individual aspects of system behavior but lack interoperable support for correlating user intent, delegation chains, authorization state, and resulting actions across domains. This creates challenges for fundamental questions required for compliance, operational debugging, and user trust, such as who initiated an action, under which authority it occurred, and how permissions evolved during execution." — "To support governance, compliance, transparency, and trust in such environments, auditing is required that collects and correlates evidence across participating domains rather than relying solely on local agent logs, where no single party has complete visibility into a multi-domain interaction. The scope of such auditing is the observable behavior of agents, including user intent, agent or tool interactions, invoked or declined actions, exchanged data, and resulting outcomes across trust boundaries, but not the auditing of the underlying AI model, training data, or inference mechanisms." — "The AUDIT effort aims to define interoperable protocol mechanisms and data models for auditing and accountability of agents and delegated systems to record, exchange, and verify audit-relevant information across Internet protocols cross all interactions in a communication chain including the user, one or multiple agents or subagents, and tools. This includes an architectural concept, common models for audit records, propagation of audit context across interactions, and integration with existing IETF protocols such as OAuth, HTTP, and attestation and transparency frameworks." The request lists technology overlap with OAUTH, WIMSE, SCITT, RATS, HTTPbis, Webbotauth, DAWN and AgentProto, and cites relevant drafts draft-kuehlewind-audit-architecture-00 and draft-birkholz-verifiable-agent-conversations-00; the mailing list is audit@ietf.org.

Proposed IETF Working Group charter "Discovery of Agents With Names (DAWN)", revision charter-ietf-dawn-00-08. Verbatim from the charter: "Clients often need to discover information about AI systems and resources (e.g., AI agents) before interacting with them. This requires obtaining information about how to reach the resources and what they offer. The focus of the DAWN Working Group (WG) is on how a client can discover public properties of AI resources to facilitate subsequent interactions such as selection, invocation, or communication. DAWN focuses on this initial discovery only and does not include open-ended search, semantic matchmaking, ranking, or selection of an AI resource based on capabilities or user intent." Scope is limited to discovery within immediate proximity, within an organization, and between cooperating parties with trust relationships over the public Internet; the charter states the WG "will specify an interoperable and generic discovery mechanism that builds on existing protocols and tools, benefits from established trust models, supports proven delegation and federation architectures, and allows organizations to have independently published discovery information", and that it "will consider DNS and mDNS as mechanisms upon which to build a discovery protocol". Deliverables: Terminology (Informational), Use Cases and Applicability (Informational), Discovery Architecture (Informational RFC(s)), and Protocol (Standards Track document(s)). Verbatim out-of-scope list for the initial phase: "Exchange of capability information beyond the minimum public discovery information"; "All communication beyond the initial discovery process"; "AI resource indexing and searching across the wider Internet"; "Identity management of AI agents, tools, and skills"; "Trust management and trust evaluation methods beyond secure content exchange between DAWN parties". Proposed milestones: DAWN Protocol specification submitted to the IESG by December 2027; DAWN Architecture by January 2028; optional terminology by June 2027. The charter states the WG will coordinate with WIMSE and OAuth as well as WGs related to DNS, discovery, identities or AI.

"Note that discovery may be an iterative process, and may use referrals, direct transfer, delegation, or indirection." The charter states the WG "will specify an interoperable and generic discovery mechanism that builds on existing protocols and tools, benefits from established trust models, supports proven delegation and federation architectures, and allows organizations to have independently published discovery information", and that it "will consider DNS and mDNS as mechanisms upon which to build a discovery protocol."

Celesto AI

Tool 2026 2026-08-25 Open source (Apache-2.0), Python frameworkA2Adurable-executionMCPopen-source

An open-source Python framework for building and operating long-running agents, covering tool use, MCP support, the A2A agent-to-agent protocol and durable execution. Its distinguishing feature is durable runs: every step is persisted so another process can finish a run after a crash, or fork it into a new one. Calling serve on an agent enables the A2A protocol automatically, making the agent discoverable to others. It works with any OpenAI-compatible provider including OpenRouter, Groq, Together, vLLM and Ollama. Notable because it treats A2A discoverability and crash-resumable execution as defaults rather than add-ons.

Verbatim from the project README: "ANP aims to become the HTTP of the Agentic Web era: a protocol suite for agent identity, naming, discovery, negotiation, secure messaging, and application-level collaboration." On why it is needed, the README states that current internet infrastructure "is mature, but it still lacks a communication and connection layer designed for large-scale agent networks", and that ANP focuses on three challenges: "Interconnection: enable agents from different platforms and domains to authenticate, discover, and communicate with each other"; "Native interfaces: let AI use APIs, protocol documents, structured descriptions, and negotiated interfaces instead of imitating human browsing"; and "Efficient collaboration: allow agents to self-organize, self-negotiate, and build lower-cost collaboration networks". It is organised as an identity and encrypted-communication layer based on W3C DID and Web infrastructure (ANP-02 DID Authentication, which separates common authentication from DID method validation including did:wba and native did:web; ANP-03 did:wba method; ANP-04 WNS Naming; ANP-09 end-to-end instant messaging plus P1-P9 messaging profiles defining DID addressing and device-bound end-to-end encryption) and an application protocol layer comprising Agent Description, Agent Discovery and Agent Application protocols. The specification index marks Agent Description (ANP-07, covering agent description documents, interface descriptions and capability publication) and Agent Discovery (ANP-08, active `.well-known` discovery and passive registration with search agents) as Released v1.2. Verbatim on positioning: "ANP reuses HTTP, CA, DNS, CDN, Search, and TLS instead of rebuilding a new network stack." The repository is Apache-2.0 licensed; the README carries a notice that the project has not issued any digital currency on any platform or blockchain.

Huawei presented the project at AGNTCon + MCPCon China 2026 (Shanghai, 6-7 September 2026) alongside its telecom path from A2A to A2A-T to OpenAN. Mirrors are also hosted on AtomGit.

Kong Inc.

Tool 2026 2026-09-30 Commercial platform with open-source SDK mcpgatewaygovernanceobservabilityenterprise

Announced 30 September 2026, extending Kong's open-source Volcano agent SDK into a full AI-native platform for building, deploying and operating agents. The strategic bet is that agents reach enterprise data through MCP rather than direct API calls, and that the durable position is the governed layer in between — handling authentication, rate limits and observability the way Kong's API gateway does for conventional traffic. The SDK demo builds a query-summarise-post workflow in nine lines; the platform supports models from Anthropic, OpenAI, Azure, AWS and GCP. The open question reported is whether developers adopt Volcano or default to larger incumbent frameworks.

Agensh (Microsoft Research): Centrally-Orchestrator-Free Multi-Agent Harness ↗ 详情

Microsoft Research

Tool 2026 2026-09-22 Microsoft Research · arXiv:2609.26781 · 项目页 aka.ms/Agensh multi-agentdecentralizedorchestrationself-organizationscaling

A multi-agent harness released by Microsoft Research in September 2026 that removes the central orchestrator entirely, letting up to 1024 agents self-organize. Each agent runs an identical five-step loop — gather shared context, claim an unclaimed subtask, execute independently, self-verify against tests, and merge results — with conflicts resolved by peer-to-peer negotiation rather than a scheduler. The paper's central claim is that agent count becomes an independent scaling dimension for model capability: overall task completion improves with agent count without upgrading the underlying model or lengthening per-agent inference. This directly attacks the scheduling-bandwidth ceiling, single point of failure and rigid task assignment of the prevailing orchestrator-worker architecture.

Microsoft

Tool 2026 2026-09-30 Open source SDK (.NET / Python) frameworkA2AMCPorchestrationcheckpointingopen-source

Released on 30 September 2026, consolidating Microsoft's previously separate Semantic Kernel and AutoGen agent stacks into a single open-source SDK spanning .NET and Python. Multi-agent orchestration is decomposed into explicit patterns — sequential, concurrent, group chat, handoff, and a Magentic-based manager-team mode. At the protocol layer it natively supports both A2A (agent-to-agent) and MCP (agent-to-tool) as complementary rather than competing paths. Engineering additions include checkpointing and resumption, so long-running tasks can continue after interruption and interrupted sessions can be exported for human takeover. Reported significance: it consolidates a fragmented orchestration landscape, and its dual A2A+MCP support signals that agent interoperability protocols are converging on a stable shape.

Tool 2026 2026-06-25 Linux Foundation Networking (LFN) candidate project, Apache-2.0 open-sourceautonomous-networksA2A-Tagent-registryorchestrationcarrier

The first open-source project for carrier agent collaboration, contributed by China Mobile and Huawei and hosted by Linux Foundation Networking as a candidate project; unveiled at MWC Barcelona in March 2026 and released at MWC Shanghai on 25 June 2026, with the first offline meeting of its eight founding members in Copenhagen on 30 June 2026. It implements A2A-T (Agent to Agent Protocol for Telecom), which extends the general A2A protocol into telecom scenarios across four domains (Task-T, Notification-T, Negotiation-T and Authorization-T), and ships three categories of components: the A2A-T common component (SDK, Registry Centre, Orchestration Centre), an Agent Framework, and an AN ontology that builds a telecom-domain knowledge graph for cross-agent semantic alignment. The registry centre is fully localizable and supports interconnection, discovery and scheduling at the thousand-agent scale, keeping all interaction traffic inside the local network and shrinking the attack surface. China Mobile chairs the project; governance sits with an Adopter Advisory Committee. The stated goal is a virtuous cycle of standards guiding direction, open source accelerating deployment and practice feeding back into standards, aligned with TM Forum autonomous-network reference architecture with commercial verification targeted for 2027.

Tool 2026 2026-10-01 Open source (Apache-2.0), self-hosted; released 2026-10-01; repository github.com/Tuskira/tusk-ai-secured-gateway (created 2026-10-01, v0.4.0) gatewayMCPgovernanceobservabilitypolicyopen-sourceagent-runtime

Verbatim from the Tuskira release announcement (SAN FRANCISCO, October 1, 2026): "Tuskira today released the Tuskira AI Agent Gateway, an open-source, self-hosted project for developers, platform teams and security teams. From one place, teams can configure models and tools, see supported calls, apply policy, control access, track token spend and switch models without reconfiguring their agents. The gateway runs entirely inside an organization's environment. It requires no Tuskira account or hosted service, and the organization retains control of its configuration, policies and logs." The announcement states the problem as: "Teams are adopting AI agents faster than they can manage them. Coding assistants such as Claude Code, Cursor, and Codex; AI productivity assistants such as Claude Desktop; and custom agents built in-house each connect to models and tools using their own settings. As a result, organizations often lack a consistent view of what their agents do, what they access and what they cost." Stated capabilities: "Route LLM calls through one endpoint… Control MCP tool access: Use centralized profiles to manage which MCP servers and tools each agent may use. Enforce access on every call: Each tool call is checked against the agent's profile at execution time. Ungranted calls are denied and every call is logged… Keep records local: Store actions, policy decisions and outcomes inside the organization's environment." The gateway "sits in the path between supported AI agents and the LLMs, MCP servers, and tools they use" and "evaluates supported actions before execution".
