针对大规模P2P网络的虚拟仿真实验床,采用了虚实结合的系统架构、基于事件驱动的高并发IO框架、基于插件架构的业务逻辑处理以及应用了相关数学模型.以虚拟仿真实验床为支撑设计的P2P污染实验案例表明,实验床既可支持8 000个节点以上的大规模虚拟仿真实验,也可将系统接入Internet,在不影响实际网络环境运行状况的同时进行真实网络实验.通过这种以虚补实、以实补虚的方式,能够加深学生对P2P等大规模网络系统运行原理的理解,进而培养学生的综合创新能力.%The characteristics of self-organization,distributing and large scale,make P2P network different from the traditional network.It is often difficult to realize P2P related experiments in the traditional experiment environment.The virtual simulation experiment bed towards large scale P2P networks uses system architecture combined by virtuality and reality,high concurrent IO framework driven events,plug-in unit based business logic processing and application of relevant mathematical models.Experiment cases show that the experiment bed can do both large scale virtual simulation experiment and real network experiment in the Internet.The real network experiment will not affect the actual operation of the P2P network.The methods of " reality supplying virtuality" and " reality verifying virtuality" can deepen students 'understanding of the P2P network and cultivate students'comprehensive innovation ability.
