The RETSINA Agent-to-Agent (A2A) Communications Library allows agent applications to interact with each other over connections that traverse the popular Gnutella peer-to-peer (p2p) network. Utilizing the same protocols and messaging constructs that Gnutella file sharing applications use, agent applications can interact with other agents, or Gnutella clients, anywhere in the world across the Internet.

Automatic processes in the library facilitate agent interactions by dynamically discovering other groups of agents with similar interests that are currently active on the Internet, and forming interlinked communities of these agents. The asynchronous managed-broadcast communications model of the Gnutella peer-to-peer network allows multiple service providers to respond to agent queries and requests. Encryption and filtering of messages to require agent-only processing of the most appropriate messages is also part of the library's core functionality.
