What is the difference between Peer-to-Peer Graphing and Peer-to-Peer Grouping?
Peer-to-Peer Graphing is the underlying communication transport that provides the stable, reliable, and robust infrastructure allowing Windows Peer-to-Peer applications to communicate. In addition, a security model can be associated with a graph to secure data and authenticate peers. Peer-to-Peer Grouping is built on top of Peer-to-Peer Graphing. Peer-to-Peer Grouping provides Microsofts security model implementation and allows multiple applications to share a graph. In addition, Peer-to-Peer Grouping uses PNRP as the discovery mechanism for IP endpoints of members in the group.
