摘　　要：本文首先介绍超节点结构P2P网络的原理,指出其存在负载失衡问题。针对其存在的问题引入信息索引机制IIM,把资源的信息索引分布到多个超节点。通过仿真实验表明,IIM能够在相对不降低搜索效率的前提下,使得各超节点的资源信息相对均衡,有效地解决了超节点结构P2P网络中超节点负载不均衡的问题。The paper firstly introduces the principle of the P2P network based on super-nodes and points out that there are problems such as load unbalance. This paper proposes an information index mechanism called IIM to solve this problem, which makes the resource index information be distributed to multi-super nodes. The simulations indicate that IIM makes the resource index information in super-nodes balancing while the search efficiency is not affected. So IIM effectively solves the load unbalance problem in the P2P network based on super-nodes.
