P2P 技术是一种分布式控制网络技术，它将逐渐取代集中式的客户/服务器结构。P2P的发展非常迅速，目前研究P2P 技术流行使用的仿真器存在可仿真协议种类少等问题。文章通过分析P2P 各种协议系统及其特性，在分析的基础上设计P2P 的通用仿真器模型。关键词：P2P；协议；仿真器Abstract: Peer-to-peer is a distributed control network technology in Internet. It will replace Internet application development from client/server architecture to the net edge step by step. Now P2P develop quickly, but popular P2P simulators can only simulate few protocol. This article design a peer-to-peer generic simulator model based on analyzing a series of peer-to-peer protocols.Key words: Peer-to-Peer; Protocol; Simulator
