HPC5: An Efficient Topology Generation Mechanism for Gnutella Networks

Free registration required

Executive Summary

In this paper, the authors propose a completely distributed topology generation mechanism named HPC5 for Gnutella network. A Gnutella topology will be efficient and scalable if it generates less number of redundant queries. This can be achieved if it consists of a fewer number of short length cycles. Based on this principle, their protocol directs each peer to select neighbors in such a way that any cyclic path present in the overlay network will not generate any redundant query. They show that their approach can be deployed into the existing Gnutella network without disturbing any of its parameters.
