摘　　要：P2P网络中节点在地址空间分布不均,负载能力大小不同,以及对Keys的访问量各异。这些特点导致了节点间负载分布极不均衡,需要引入平衡机制。针对结构化P2P网络特点提出的算法在搜集节点的负载信息过程中只消耗极少的额外网络资源,同时还通过重定位解决了虚拟节点带来的负面效果。In peer-to-peer （P2P） networks, node namespaces are imbalance, node capacities of loading are different and queries amount for Keys are also varied. These characteristics bring on workload distribution extremely uneven between nodes and need to adopt balancing mecha- nism. This paper proposes a new algorithm which consumes little extra network resource to collect node workload information. And it also solves the negative results brought by virtual nodes through relocation.
