Abstract: In hybrid P2P network, a super peer is able to render other peers services, such as information collection and search, data relay, and NAT traverse. Due to the high dynamic characteristic of P2P network, it is difficult to design a hybrid P2P network with super peers. This paper designs a balanced, robust, self-adapted hybrid P2P network model. The focus of research work is super peer’s load balancing, robustness, self-adjusted mechanism, and failure detect and recovery. New strategies and simulation for those topics are presented.

Key words: P2P, super peer, load balancing, robustness

摘要： 超级节点为其他节点提供各种服务，包括信息的收集与检索、数据传送及穿越NAT等，但P2P系统的高动态性为设计一个有超级节点的混合P2P网络带来困难。该文设计一种均衡、健壮、具有自适应能力的混合P2P网络模型，研究超级节点的负载均衡、健壮性及自我调整策略，提出新策略以解决超级节点失效时带来的问题。
