In the last few years, overlay networks have rapidly evolved and emerged as a promising platform for deployment of new applications and services in the Internet. One of the reasons overlay networks are seen as an excellent platform for large-scale distributed systems is their resilience in the presence of failures. This resilience has three aspects: data replication, routing recovery, and static resilience. Routing recovery algorithms are used to repopulate the routing table with live nodes when failures are detected. Static resilience measures the extent to which an overlay can route around failures even before the recovery algorithm repairs the routing table. Both routing recovery and static resilience rely on accurate and timely detection of failures.

                  Peer-to-Peer (P2P) Overlay Diagnostics


   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.
