# Peer-to-peer Communication Between Nodes

Peer-to-peer (P2P) communication enables nodes to self-organize into a globally distributed network of Cardano block producers and relays, and also self-optimize, choosing the best and more performant connected nodes and disconnecting from less performant ones. 

Information is exchanged between nodes to enable a flexible network topology that automatically adapts to dynamically changing network conditions. This further boosts network decentralization, resilience and robustness.

The network's P2P architecture includes four elements:

* P2P Governor
* Connection Manager
* Server
* Inbound Protocol Governor
