P2P模式下的资源定位技术探究

在P2P模式的网络环境中,如何迅速的对节点资源进行定位和建立连接,是网络技术研究的重点之一.针对P2P混合型模式的资源定位和搜索算法中存在冗余消息等问题,通过算法分析,提出两种改进思路和方法：一是减少查询的冗余消息;二是查询到的信息直接发送给起始的查询节点.通过仿真实验,表明改进后的算法,减少了查询消息冗余和提高了搜索速度.

The Research to Resource Positioning Technology of P2P Mode

In the P2P mode network environment,one of the key points to the study of network technology is how to positioning and connecting the node resources.For the problems of P2P hybrid model＇s resources location and the redundant messages in the search algorithm,this paper provides two kinds of improved ideas and methods.One is reduce the query redundancy messages,and the other is sent the inquired messages directly to the start of the query node.The simulated experiment proved that the improved algorithm reduced the query message redundancy,and improved the search speed.
