Executive Summary

Peer-to-Peer overlay systems offer a substrate for the construction of large scale and distributed applications. The Peer-to-Peer technique is differentiated in to two major forms, Structured P2P and Unstructured P2P. In structured peer-to-peer networks, connections in the overlay are fixed. They typically use Distributed Hash Table-based (DHT) indexing, such as in the Chord system. Unstructured peer-to-peer networks do not provide any algorithm for organization or optimization of network connections. Hence the functions like searching, querying etc. are mostly flooded. In this paper, the authors propose a novel message passing technique in which each peer maintains the route path of the destination with in itself which uses this route path to send and receive messages.
