Dynamic workload balancing for collaboration strategy in hybrid P2P system

Abstract

The peer-to-peer (P2P) systems have grown significantly over the last few years due to their high potential of sharing various resources. Analyzing the workload of P2P system, however, is very challenging as it involves with the cooperation of many peers. Researches have shown that P2P systems become very effective when dividing the peers into two layers, SP (Super-Peer) and OP (Ordinary-Peer). In this configuration, SP based P2P systems have to deal with a large volume of queries from OPs. Therefore, it is important for SPs to keep their workload stable to provide quality service to the OPs. In this study, we present a collaboration strategy for workload balancing based on SP's workload characteristics and status. Through the SP's load balancing mechanism, the message response time is decreased and the workload of P2P system becomes more stable. © Springer-Verlag Berlin Heidelberg 2007.
