摘要 介绍传统超节点结构P2P网络中的查询方法,指出其存在负载均衡问题和单点失效问题。针对其存在的问题引入资源索引和冗余机制,把资源的索引信息分布到多个超节点。通过仿真实验表明,该机制使得各超节点的资源索引信息相对均衡,并且在相同概率的超节点退出时,提高了查询成功率。 Introduces the traditional search method in P2P Network based on super-node, points out the problems such as load equilibrium and single node-failure. Aiming at the problems the paper proposes resource index and redundancy mechanism, which distributes the resource index information to multi-super-nodes. The simulation experiments indicate that the mechanism makes the resource index information in super-nodes equilibrium and improves the search success rate when the super-nodes exit the system by same probability.
