Agent Mesh Networking Pattern
As agent ecosystems grow, centralized orchestration doesn't scale — you can't pre-program every collaboration. The mesh pattern treats agents like microservices: each publishes an agent card to a registry, any agent can discover and invoke others that match its needs, and routing emerges at runtime. A2A is the transport; the organizational pattern is the mesh. Early 2026 is the first year this is deployed beyond toy demos.

Frequently asked questions
Why mesh instead of central orchestrator?
Central orchestrators become bottlenecks when you have dozens of agent teams across an org, each building their own agents. Mesh lets teams ship independent agents that still interoperate, analogous to microservices vs. monolith.
What are the open problems?
Trust (how do I know a mesh-discovered agent is legit?), observability (tracing across an unpredictable call graph), and cost attribution (who pays when agent A calls agent B calls agent C?).
Is this just microservices with LLMs?
Similar ideas, different failure modes. Microservice calls are deterministic; mesh-agent calls have hallucination and cost variance. Mesh patterns are borrowing heavily from service-mesh infrastructure — Istio-style sidecars for agents are an active research area.
