      <name>Introduction</name>
      <t>AI agents are increasingly deployed for network management tasks <xref target="I-D.wmz-nmrg-agent-ndt-arch"/> — including service provisioning and network configuration change, service assurance and automated incident diagnosis and resolution. While the introduction of agents significantly improves the efficiency for network management, it also inevitably brings challenges such as hallucination and execution unreliability.</t>
      <t>Existing mechanisms for agent assurance typically rely on static guardrails (e.g., input/output validation, operation allowlists/blocklists, pre-action approval), while assuming that all agent failure modes can be predefined. Unlike deterministic software systems, however, LLM-based agents exhibit emergent behaviors that cannot be fully anticipated or encoded in static rules. When agentic systems produce novel actions or reasoning paths that fall outside predefined static boundaries, it might lead to risks such as unintended configuration changes, policy violations, or cascading failures in the network.</t>
      <t>The operational problems, architectural challenges, and technical gaps regarding the observability, control, and intervention of autonomous network management agents are thoroughly detailed in <xref target="I-D.wnd-opsawg-icon-ps"/>.
This document builds upon those identified gaps to specify a set of essential requirements that supervisors need when deploying agents in real networks for agent observability, control, and intervention. Furthermore, it also defines an architecure for ICON — Intervention, Control, and Observability for Network Management Agents.</t>
      <t>This document specifies the architecture and communication requirements between the agent and the supervision system. It does not standardize the internal LLM architecture, planning algorithms, or training methodologies of the network management agents themselves.</t>
      <t>This document does not specify a particular protocol, data model, or implementation API. Those topics are orthogonal to the operational requirements defined here, which are intended to be solution-neutral.</t>

      <name>Existing Mechanisms for Agent Observability, Control, and Intervention</name>
      <t>After receiving a user request, agents will perform a chain-of-thought (CoT) reasoning process, then it will autonomously decide whether to break down the task into subtasks, or dynamically decide to invoke multiple external tools, retrieve vector databases (RAG), or request more information from the supervisor.</t>
      <t>Existing telemetry mechanisms are excellent for tracking traditional network infrastructure or software which are built for deterministic systems. However, as analyzed in <xref target="I-D.wnd-opsawg-icon-ps"/>, they are facing severe limitations when applied to AI agents. For example, existing logging practices only record what action was taken, completely missing why it was taken, including the agent's internal reasoning provenance and confidence scores. Existing tracing mechanism designed for static and linear execution path also cannot capture the complex and dynamic execution trajectories of AI agents.</t>
      <t>Existing AI guardrails primarily operate at static boundaries, such as input/output validation and pre-action checks. These mechanisms are designed to constrain AI agents within predefined operational and compliance boundaries, but they assume that all possible violations can be anticipated and encoded in static rules. As AI systems increasingly operate in non‑deterministic environments, these static measures are proving insufficient as they cannot detect, interrupt, and recover from unanticipated behaviors.</t>
      <t>Although there are some modern agent systems that provide interrupt or kill switch capabilities, they remain framework-specific, insufficient, or proprietary.</t>
      <t>These gaps motivate the architectural framework and requirements for agent observability, control, and intervention defined in <xref target="architecture"/> and <xref target="requirements"/>, respectively.</t>

        <name>Human Oversight</name>
        <t>Human oversight represents the top-level authority of the agent management. It provides the post-execution feedback, injects global policies, reviews agent escalation requests, and issues high-level intervention commands during crises or anomalies.</t>

              <dd>
                <t>Human operators could express high-level operational constraints or boundaries. These intents are translated into machine-readable policies by ICON client and sent to the policy enforcement component.</t>

              <dd>
                <t>When an active agent encounters an ambiguous scenario, a conflict between different policies, or a decision whose confidence score falls below a predefined threshold, the execution plane suspends the task and escalates it to operators. A human operator could either approve, reject, or modify the agent's pending action sequence.</t>

                <t>In the scenario of an unforeseen and deviated agent behavior (e.g., an agent entering an infinite inference loop or executing based on outdated data or incorrect assumption), human oversight allows immediate, manual injection of high-priority override instructions (e.g., global kill switches or behavior corrections).</t>

              <dd>
                <t>Beyond runtime intervention, operators could also provide a critical retrospective evaluation feedback. Following an incident, anomaly, or successful resolution, human operators may inject multi-dimensional feedback (e.g., critiquing the agent’s reasoning paths, correcting intermediate planning errors, or evaluating the quality of tool selection). This retrospective feedback could be used to update the prompt templates or refine downstream guardrail policies, preventing the recurrence of similar behavioral drifts.</t>

          </li>
        </ul>
        <t>It is worth mentioning that human operators rarely send raw agent control or intervention protocol payloads directly. They could use more flexible and human-friendly formatting such as natural language which is relayed to the agent management plane to translate into structured control or intervention signals for normalization and distribution.</t>

              <dd>
                <t>It hosts the emergency orchestration logic required to reactively instruct agents in response to boundary violations, anomalies, failures, or operational risks. Upon detecting critical policy violations or receiving manual override commands from human oversight, it generates specific instructions (such as pause or terminate) and pushes them down to the enforcement component. In addition, it also receives upstream messages initiated by agents, such as escalation requests that proactively require human intervention.</t>

        <name>Agent Execution Plane</name>
        <t>An Agent Execution Plane is the runtime environment where AI agents operate, invoke tools, and interact with the network infrastructure. It receives the high-level intent sent from the network operator, performs the LLM reasoning, and takes corresponding actions step-by-step. It might also route some of the execution to other agent. Each execution step might involve invoking tools, APIs, or agent skills. After task completion, it collects execution status, operational logs, and network state results, and delivers feedback and reports to the network operator.</t>
        <t>The execution plane enforces policy enforcement at multiple critical points throughout the agent execution, including before agent task-processing, pre-action, and before delivering final responses to the operator.

For example, when an agent fails to provision a network service, the supervisor triggers a full task rollback to wipe out the entire provisioning attempts across all affected nodes.</t>

                <t>Reverts all network operations across multiple related tasks bound by the same context. This acts as an ultimate rollback mechanism to reset the entire multi-turn interaction or back to its original historical baseline. For example, during a multi-turn network troubleshooting conversation, an agent executes three tasks under the same context to mitigate an anomaly. If supervisor realizes the entire investigation pathway was flawed, they may select context level rollback to comprehensively wipe out all configuration changes made across all three tasks in this specific context.</t>

            <abstract>
              <t>   This document provides an overview of the issues associated with the
   deployment of the observability, intervention, and control of
   autonomous agent pipelines in large-scale heterogeneous network
   environments.  The term "Intervention and Control" is used to
   describe a set of automated and human-initiated mechanisms that
   guarantee the capability to observe, constrain, correct, and
   terminate Autonomous agents at any point, for any reason,
   irrespective of their level of autonomy under which it operates, to
   ensure resilience, recovery, and operational continuity.

   The set of enabled observability, intervention and control reflects
   operator service offerings to ensure that autonomous operations can
   be stopped, or safely redirected when required and is designed in
   conjunction with agent to agent, agent to tools, agent to human
   interaction and service and network policy.

   This document also identifies several key areas that the Agent
   Observability, Intervention and Control group will investigate to
   guide its architectural and protocol work and associated documents.

            <abstract>
              <t>   A Network Digital Twin (NDT) provides a network emulation tool usable
   for different purposes such as scenario planning, impact analysis,
   and change management.  Agentic AI enables dynamic goal-driven
   execution and adaptive behavior and closed-loop autonomy.  By
   integrating a Network Digital Twin into network management together
   with the Agentic AI, it allows the network management activities to
   take user intent or service requirements as input, automatically
   assess, model, and refine optimization strategies under realistic
   conditions but in a risk-free environment.  Such environment that
   operates to meet these types of requirements is said to have AI
   driven Network Operations.

   AI driven Network Operations brings together existing technologies
   such as Agentic AI and Network Digital Twin which may be seen as the
   use of a toolbox of existing components enhanced with a few new
   elements.

   This document describes an architecture for AI driven network
   operations and shows how these components work together with network
   digital twin and Agentic AI capabilities.  It provides a cookbook of
   existing technologies to satisfy the architecture and realize intent-
   based network management to meet the needs of the network service.
