Peer to peer messaging is a simple information dissemination platform that is supported by a protocol which is based on pairs of request/response PDUs (protocol data units, or packets) exchanged over OSI layer 4 (TCP session or X.25 SVC3) connections. PDUs are binary encoded for efficiency. Data exchange may be synchronous, where each peer waits for a response for each PDU being sent, and asynchronous, where multiple requests can be issued without waiting and acknowledged in a skew order by the other peer; the number of unacknowledged requests is called a window; for the best performance both communicating sides must be configured with the same window size.

Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in most messaging applications. In such social contexts, peer-to-peer as a name refers to the egalitarian social networking that is currently emerging throughout society, enabled by Internet technologies in general through flexible emerging electronic devices.
