摘要：Distributed network computing environments have become a cost effective and popular choiceto achieve high performance and to solve large scale computation problems. One importantissue in the DHT design is how to balance the load across the nodes in the system. To achieveload balance, existing DHT-based P2P systems simply resort to the hash function to mapobjects to nodes randomly. However, the use of DHT and the heterogeneity of nodescapacities may give rise to load imbalance problems, and affect the DHT system efficiency aswell. In this paper, A new load balance algorithm, static load distribution algorithm and dynamicload adjustment algorithm (SDDA) is proposed, SDDA is designed based on the concept ofvirtual server, The new algorithm can dynamically adjusts Address-Space and fairnessworkload for each node after measured it's capacity. Through research and simulationanalysis, compared with the traditional virtual server load balancing algorithm, the SDDAalgorithm is with better load balance, faster velocity of load balancing, less load movementcost, and more excellent stability of P2P system. © 2013 by CESER Publications.
