Agentic Overlays & Agent-to-Agent Fabrics – Making Autonomous Agents First-Class Network Citizens
Agentic AI overlays promise networks that sense, reason, and act—but the real challenge is treating AI agents as first-class identities in the network. Building on ONUG’s A2A and Agentic Overlay concepts, this session explores how to standardize identity, trust, and messaging among agents, and how those agents interact with the underlying network fabric.
Key Questions: – What should an A2A reference architecture look like in a large enterprise (broker vs. mesh, policy dialects, schemas)? – How do we provide Zero-Trust identity and least-privilege capability routing for agents issuing network changes? – What telemetry is needed to link agent intents → network changes → workload outcomes → cost? – How do you avoid “agent sprawl” and conflicting policies across multiple vendors’ AI assistants?
Takeaways: – A clear mental model of Agentic Overlays and A2A in networking. – Governance patterns for letting agents safely orchestrate NaaS, routing, and provisioning.
