P2P Overlay Diagnostics
draft-ietf-p2psip-diagnostics-11
Abstract
This document describes mechanisms for P2P overlay diagnostics. It
defines extensions to the RELOAD P2PSIP base protocol RELOAD
[I-D.ietf-p2psip-base] to collect diagnostic information, and details
the protocol specifications for these extensions. Useful diagnostic
information for connection and node status monitoring is also
defined. The document also describes the usage scenarios and
provides examples of how these methods are used to perform
diagnostics in a P2PSIP overlay networks.
