将和弦JXTA定位机制

JXTA-Chord 本项目基于SUN提出的开源对等网络通信平台JXTA，试图提高JXTA的路由定位效率，使其更加适合于大规模分布式动态网络。本项目提出了一种结合非结构化和结构化网络的混合式架构，在JXTA原超结点结构适当修改基础上替换原松散一致DHT定位方法，引入Chord路由定位机制，修改JXTA协议。同时，通过修改JXTA在JAVA平台上的实现JXSE完成了该方案形成jxse-zengqiang版本。 对jxta路由定位机制的详细分析及松散一致性DHT的缺陷论述和该修改方案的具体设计和实现可参见本人毕设论文和相关文档(已上传部分)。 This is a modified version of JXSE v2.5. I integrated the Chord protocol into JXTA and designed a hybrid location model combining the structured and un-structured network location mechanisms. The experiments show that the modified version outperforms the JXSE2.5 by more than 1.5 times and has a higher query hit ratio in case of node failures. It is more scalable in a large-scale distributed dynamical network.
