Peer Channel is a multiparty, peer-to-peer (P2P) communication technology in Windows Communication Foundation (WCF). It provides a secure and scalable message-based P2P communication channel for application developers. One common example of a multiparty application that can benefit from Peer Channel is a collaborative application, such as chat, where a group of people chat with one another in a peer-to-peer manner without servers. Peer Channel enables P2P collaboration, content distribution, load balancing, and distributed processing for both consumer and enterprise scenarios.
Peer Channel is enabled by default on Windows Vista, as is all of WCF. To access Peer Channel classes, add references to System.ServiceModel.dll to your project.
