Abstract:

To provide efficient topology aware service, the transmission loss effects and the metric space property of peer distances in peer to peer (P2P) overlay network are discussed, the P2P clustering service is proposed as well. The service solution manages P2P client peers and maintains clustering view (CV) with clustering initiation and optimization interfaces and algorithms, and supports crossapplication topologyaware with CV querying interfaces and the CV mapping algorithm. Simulation indicates that the solution provides more accurate recommendations of closest neighbors than traditional methods based on coordinate space.

Key words: peer to peer, clustering service, topologyaware
