摘要
由于P2P网络的动态性,如何有效和准确地进行对等点定位成为P2P网络中的关键技术。本文在分析现在P2P网络中几种常见的对等点发现机制的优点与不足的基础上,提出了利用IP多播技术和JXTA平台实现的对等点发现机制,并讨论了其在P2P文件共享系统中的实现方法。
Because of the dynamic property of P2P networks, how to locate the peers effectively and exactly has become the key technology of P2P networks. In this paper several widely used discovery mechanisms in P2P networks nowadays are analyzed. The merits and shortcomings of these mechanisms are pointed out. A peer discovery mechanism using IP Muhicast technology and JXTA platform is proposed, the implementation in P2P file share system is also discussed.
