一种基于DHT的P2P搜索方法

在网络搜索技术中,P2P模式有C/S模式无可比拟的优势。P2P为非中心化结构中的网络用户赋予更多的权力,使网络应用的核心从中央服务器向网络边缘的终端设备扩散,因而可以全面改写当前的网络搜索技术。在各种P2P技术中,搜索技术是最有价值、最亟待解决的问题,其中分布式哈希表(DHT)协议将是对等网搜索的重要发展方向。本文首先概述P2P搜索技术现状,接着分析比较了当前几种典型的协议搜索方法,最后讨论一种基于分布式哈希表的协议搜索方法。

Research of P2P searching technology Based on DHT

Peer- to- Peer systems have unexampled superiority to Client/Server networks on search technology. The P2P networks en- dows more rights for network users of the non- centralized net structure, and lead to the networking application function delivered from centralized servers to terminal systems which lie in the edges of networks. As a result it can generally change the currently net- work searching technology. In all kinds of P2P techniques, P2P search method is the most urgent problem to be solved as it is the basis of the P2P system, And the distributed hashing table (DHT) methods are the most potential direction in the future research. This paper introduces the status of the P2P searching technology firstly. Secondly several typical P2P protocol searching methods are discussed. Finally we propose a DHT based protocol searching method.
