对等网络搜索技术的研究

Study of search technology in peer-to-peer networks

网络资源的动态变化,使得传统的搜索引擎技术有些力不从心。而JXTASearch是一种基于JXTA对等网络的搜索机制,它具有即时掌握资源状态变化,快速定位资源的特点。本文详细分析了JXTASearch的工作原理,分别阐述了JXTASearch基于JXTA平台和基于Web服务的2个搜索过程,归纳总结了JXTASearch的技术优势,着重说明了基于JXTA平台搜索和基于Web服务搜索的实现,最后提出了JXTASearch需要不断完善的方向。

The dynamic change of network resource makes the conventional search technology＇s ability not equal to its ambition. JXTASearch is about peer-to-peer search technology based on JXTA platform, it can know the change of the resource in time and go to the resource quickly. We analyzed the principle of JXTASearch in detail, respectively described its search processes based on JXTA platform and based on Web service, concluded the advantage of JXTASearch, explained the realization of searching based on JXTA platform and based on Web service in this paper. At last , brought forward the direction which JXTASearch has to be perfect.
