结构化P2P网络模型的改进

文章通过对现有P2P网络[1,2]模型的分析,指出了现有网络模型的缺陷,并建立了一种节点分级网络模型(HNN)。HNN在继承了DHT算法路由的所有优点(如很强的鲁棒性)的同时,通过对网络节点带宽和位置信息的引入,解决了原有网络模型因哈希(HASHING)而引起的对实际网络拓扑结构的破坏问题,使虚拟网络模型更好地与实际网络的小世界特性相匹配。

By analyzing existing peer-to-peer network model, the shortcomings of the network are pointed out and a model of hierarchical nodes network （HNN）is built. While inheriting all advantages of DHT algorithm routing （e.g.Robust）, HNN can resolve the topology stnlcture of real network destroyed by old network model because of hashing through the introduction of the bandwidth of network nodes and position, which match better virtual network model to the characteristics of actual network model.
