摘　　要：为了加强基于JXTA的对等网络的搜索性能,研究分析了JXTA网络中集合点的管理策略及查询机制。针对现有网络集合点管理措施的缺陷以及由此可能导致网络查询效率低下的问题,提出了应用移动Agent来协助JXTA进行集合点选择的方案,以达到选择综合性能优秀的节点来充当集合点的目的,并在此基础上给出了改进后的查询机制。最后,在局域网内进行了模拟实验,通过实验结果的对比分析表明,改进后的机制能够极大地优化JXTA网络的整体查询性能。The method of rendezvous management is mainly introduced and the search mechanism of JXTA network for strengthen the ability of search in the JXTA network is analyzed.Aimed at the fault of present methods of rendezvous management and the inferior ef-ficiency as the result of themselves,an improvement method of strengthen the rendezvous peer management and messaging based on mo-bile agent in the JXTA network is proposed.The purpose of achieving comprehensive performance excellent choice to serve as a rendez-vous,then in terms of these conditions,an improvement search mechanism is given based on these conditions.In the end,the experiment is implemented in LAN.Compared to original search mechanism,the improvement method is proven it is more effective and it optimize the search mechanism in JXTA network by analyzing the experimental results.
