Multi-Agent System

Build and deploy multi-agent systems with ARC Protocol.

Overview​

Multi-agent systems distribute functionality across specialized agents that communicate via ARC Protocol.

Deployment Options​

Single Server​

Deploy multiple agents on one server for simplicity and low latency.

Best for:

  • Development and testing
  • Related business domains
  • Low to medium traffic
  • Shared dependencies

Guide: Single Server Deployment

Distributed​

Deploy agents across multiple servers for scaling and isolation.

Best for:

  • Production systems
  • Independent scaling requirements
  • Fault isolation
  • High availability

Guide: Distributed Deployment

Agent Communication​

Agents communicate via ARC Protocol with workflow tracing.

Key Concepts​

Agent Independence​

Each agent is self-contained with its own:

  • Business logic
  • Data storage
  • Dependencies
  • Scaling characteristics

Protocol-Based Communication​

Agents communicate through ARC Protocol, not direct calls:

  • Loose coupling
  • Technology independence
  • Easy testing and mocking
  • Clear boundaries

Workflow Tracing​

traceId enables end-to-end tracking across agent interactions.

When to Use Multi-Agent​

Use multi-agent systems when:

  1. Domain Separation - Clear business domain boundaries
  2. Independent Scaling - Different agents have different load
  3. Team Organization - Different teams own different agents
  4. Technology Diversity - Agents use different tech stacks

Quick Start​

1. Define Agents​

Finance Agent - Handles invoices, payments
HR Agent - Manages employee queries, benefits
Support Agent - General customer support

2. Choose Deployment​

  • Development: Single server
  • Production: Distributed

3. Implement​

Follow the appropriate guide:

4. Connect​

Implement agent-to-agent communication:
