在结构化P2P系统中,由于使用分布式散列表,各节点能够达到基本的负载平衡.但是,各个节点由于承担负载的能力不同和数据的存取存在"热点"现象,因此仍然存在负载不平衡的情况.针对这一缺点,采用局部信息调整负载的方法,提出了分布式负载平衡算法,从而避免了单点失效问题,同时算法的实现更为简单.

In DHT-based structured P2P system,as a result of the use of distributed hash table,every node can achieve the basic load balancing,but nodes have different capacity to bear the load,and data access has "flash crowds" phenomenon,so there are still load unbalancing in every node.For this disadvantage,we proposed an algorithm for distributed load balancing in which local information adjusts load.And then the problem of single node invalidation is avoided,the implement of algorithm is very simple.
