A peer-to-peer network is a multi-agent pattern with no central coordinator. Agents share knowledge or partial results directly and work toward a collective solution. They may broadcast information or negotiate rather than follow a top-down plan. section 4.1.3
Unlike hierarchical coordination, where one agent delegates work, no single agent oversees the peer-to-peer process. This makes the pattern useful for distributed decisions and situations where the team must remain robust as agents fail, join, or leave. section 4.1.3 section 4.6
Cybersecurity monitoring
Detector agents exchange alerts and insights to identify threats collectively, without relying on one leader. Each alert contributes to a shared decision rather than waiting for a central agent to direct every step. section 4.1.3
Check the coordination costs before choosing this pattern:
- Use it when distributed decision-making and fault tolerance matter. section 4.1.3
- Avoid it when actions need strict global control or a clear sequence; agents can develop inconsistent views or encounter race conditions. section 4.1.3
- Plan for growing communication overhead and a shared strategy for resolving conflicts. Without one, agents may drift or deadlock. section 4.1.3
