    abstract =  {This document presents an architectural framework for an Agent Communication Gateway (Agent-GW), designed to support large-scale, heterogeneous, and dynamic multi-agent collaboration across administrative and protocol boundaries. As agents evolve from isolated entities to a collaborative digital workforce, the infrastructure must transition from rigid, endpoint- based connectivity to intent-based interaction. This draft proposes Agent-GW as an infrastructure hub that provides native primitives for Semantic Routing (dispatching tasks by intent and capability), Working Memory (shared structured context across multi-step workflows), automated protocol adaptation (normalizing heterogeneous interfaces into a unified agent-facing protocol), oracle-free agent evaluation, and collaborative inference acceleration via a Knowledge Delivery Network (KDN). Beyond a single-gateway deployment, this document defines a hierarchical architecture for wide-area, multi-domain agent networks: three gateway tiers (access, domain, and inter-domain). It describes which traffic classes traverse which tiers on both the data plane and the control plane, and specifies cross-domain semantic routing, name resolution, resilience, and operational considerations.},
