NBean: A HeteroPastry-Based P2P Proxy System

For the problem that current centralized services rarely could satisfy free, stable and universal at the same time, the P2P proxy system NBean has provided a span-new solution to network-proxy services. Nodes which participate in the system compose a P2P overlay network based on HeteroPastry protocol, and the system chooses several appropriate nodes to form a proxy chain every time in order to response users' varied requests. The experiments show that NBean can balance the load upon the network efficiently when providing high quality services.
