P2P网络中基于文件路由模型搜索方法的改进

资源搜索和共享是P2P网络中重要的应用。针对当前P2P网络中现有共享资源搜索方法还存在诸多不足之处的问题,提出了一种基于文件路由模型改进的搜索方法。该搜索方法选取多个稳定对等体共同作为共享信息的载体,在利用哈希函数分配共享信息及其索引的基础上,提出了一种新的数据结构来记录所有存储了同一共享信息的稳定对等体信息,增强了系统的健壮性,同时均衡分配共享信息载体的负荷,合理利用网络带宽,使P2P网络在资源搜索和共享方面得到了一些改善。

Improvement of Search Method Based on Document Routing Model in P2P Network

Resource searching and sharing is very important application on peer-to-peer network.At present,there are also many problems of existent shared resource search method on peer-to-peer network.An improved search method based on document routing model is proposed,it picks some stable peers as the common carrier of shared resource,and on the basis of allocating shared resource and its index information with Hash function,a new data structure is built to record information of all peers which store identical shared resource.With the improved search method above,system reliability is strengthened,burthen of shared resource carriers go balanced and network bandwidth is used rationally.As a result,it brings P2P network some improvement in aspect of resource searching and sharing.
