Service Extensible P2P Peer Protocol
Hewen Zhang, Xingfeng Jiang · 2008
This document describes the Service Extensible Protocol (SEP), which is the peer protocol spoken between P2PSIP Overlay peers to share information and organize the P2PSIP Overlay Network. SEP uses a flexible forwarding mechanism to avoid congestion in the Overlay. It also proposes a general service discovery method and a built-in NATtraversal mechanism. By using these methods, SEP tries to improve the success rate and reduce the latency of the transaction.
