Peer-to-Peer (P2P) Overlay Diagnostics
Abstract
This document describes mechanisms for Peer-to-Peer (P2P) overlay
diagnostics. It defines extensions to the REsource LOcation And
Discovery (RELOAD) base protocol 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.
