A P2P network based on Super-Peers could both improve the efficiency of query algorithms and decrease relevant traffic.It is a hotspot in P2P network research in China and abroad.Eliminating redundant super-peers is one of the important challenges in designing this type of P2P network.First,the proposed method uses a unified load evaluation measure-the resource consumption factor-to replace the uncertainty of former load evaluations.Second,two virtual-super-peer algorithms are put forward in this paper.They are designed to select a lightly loaded peer in a given domain or another super-peer outside of the domain,and then construct a virtual-super-peer by combining a current super-peer and the selected peer,or ′partner-peer′.Simulations show that the algorithm increases network self-adaptation to variations in traffic and improves network′s robustness and resource availability with little overhead cost.
