摘　　要：现今广阔的互联网正承载着越来越多的大数据量传输任务,在传输过程中这些数据往往需要占用大量的网络资源。Peer-to-Peer技术虽然以其新的方式在新环境中迅速发展,但各种P2P模式都具有无法反映物理网络拓扑的特点。传输过程中物理网和覆盖网的脱节致使P2P的路由效率受到很大的限制并给网络带来了更多的负载。通过对WHOIS协议的研究,根据对各ISP在注册服务机构提交的网络注册信息中提取关键信息来构建较完整的物理拓扑网,使P2P通信过程中能借助文中所构建的物理拓扑网来实现拓扑感知,从而使P2P节点通信的获得更高效率和产生更低负载。Nowadays Internet is loading more and more huge - amount data transferring mission, and thee data usually occupy large amount of network resource in the process of transmission. Peer- to- Peer technologies have gotten great development in the new communication environment, but various P2P pattern has the characteristic which can＇t reflect physics network topology. In the process of transferring,the unmatch of physics network and overlay network is affecting the P2P route efficiency and bringing more network flow. Through analysing the WHOIS,on base of those network registration information which come from register serving organization intend to build a basically completed physics topology network. So the Peer- to- Peer will achieve topology - aware which can keep the nodes in the system have high efficiency and produce low network load.
