Abstract: For the problem that the centralized network proxy server would become a bottleneck, this paper provides a solution to network-proxy services. Nodes which participate in the system compose a Peer to Peer(P2P) overlay network based on HeteroPastry protocol, and the system chooses several appropriate nodes to form a proxy chain in order to response users’ varied requests. Experimental results show that the system can balance the load upon the network efficiently when providing high quality services.

摘要： 针对集中式网络代理服务器经常产生瓶颈的问题，提出以P2P方式提供网络代理服务的解决方案。参与系统的节点组成一个基于HeteroPastry协议的P2P覆盖网，系统在覆盖网中挑选一些合适的节点组成代理链，以响应用户的不同请求。实验结果证明，该系统可以在提供高质量服务的同时有效地平衡网络负载。
