JXTA网络中资源搜索模型的研究与实现

Research and Implementation of JXTA Network Resources Search Model

本文改进了对等节点的功能分工和网络层次结构,并引入移动Agent技术,通过移动Agent在集合点之间传播查询通告,提出了一种基于JXTA技术和移动Agent的新资源搜索网络模型,并实现了一个建立在P2P网络上的使用移动Agent进行资源搜索的系统——AJMAS。实验结果表明,通过改进网络结构及相应的搜索策略,能够极大地提高网络的适应性和搜索速度。使基于JXTA协议的P2P网络不再仅仅是一种理论上的研究模型,它将具有很好的应用前景。

This article improves the function of peer nodes and networks division of the hierarchy,and introduces the mobile Agent technology. Trough spreading search notices between collection points by mobile Agent,the paper proposes of the new resource search network model based on JXTA technology and mobile Agent, and implements a P2P network based on mobile Agent system for resource search AJMAS. Experimental results show that by improving the network structure and the corresponding search strategy, the network flexibility and search speed can be greatly improved. The P2P network of based on JXTA protocol is no longer just a theoretical research model, it will have a good application prospects.
