摘要
现有的主流P2P技术都没有很好解决路由容错问题,影响了网络性能的提高。根据deBruijn有向图的理论和节点的性能,把P2P网络拓扑结构划分成两层,在此基础上设计了一种对路由容错进行特别优化的P2P路由算法:FT-p2p。实验结果表明:FT-p2p算法比Chord等算法表现出更好的路由容错性能,具有良好的实用价值。
The current mainstream P2P technology has not solve the problem of fault - tolerant routing , which affects the performance of P2P network. According to deBruijn directed graph theory and node performance, P2P networkt topology is divided into two layers, on the basis of which FT - P2P, a P2P routing algorithm is designed and it is es- peciaUy optimized to fault - tolerant routing. The experimental results indicate that Ft- p2p algorithm is superior to Chord algorithm in fault - tolerant routing and has good practical value.
