Google Agentic Architect - Subconcept 1.2: Multi-Agent Topologies (The Coordination Mesh)

Contrast three primary multi-agent orchestration topologies: Router (Triage/Dispatch), Hierarchical Supervisor-Worker, and Sequential DAG pipelines. Explain the operational trade-offs of each pattern regarding orchestration overhead, end-to-end latency, and state complexity. Describe a router as a low-latency, single-hop intent classifier where control does not return to the dispatcher. Then, break down how a central Supervisor coordinates a pool of specialized worker agents, constructs dynamic task graphs, manages worker isolation, and aggregates state deltas. Provide concrete guidelines for selecting the correct topology based on the predictability of the business workflow.
