层次网络仿真系统设计与实现

The Design and Realization of Hierarchical Network Simulation System

基于Internet的通信子网中的通信通常使用C/S(客户端/服务器)模式,这种通信模式决定了不利于人们跨地城进行资源共享。因此,必须打破网络以Internet为基础设施的格局,使每台在线计算机都具备双重身份:既是客户端又是服务器,实现对等通信。本文分析了目前流行的对等网络模型的不足,提出了一种有充分优越性的对等通信网络模型一层次网络模型DataGrid,通过仿真此网络系统的运行,并针时各种因素测试其网络性能,找出性能值最优的层次网络拓扑,给出组网建议和指导信息。

Communication in the communication subnet based on the internet usually uses C/S mode. The localization of the communication mode decided it isn＇t advantageous for sharing the source among the different districts. Therefore, we must break the pattern that the network is based on Internet. Each computer on line has diplex identiw—it is a client and also a server. In this paper, the shortage of two popular peer-to-peer network mode are analyzed. A predominant peer-to-peer hierarchical network mode—DataGrid is proposed. Through simulation of this network＇ s running the best hierarchical network topology is fond out and construction and direction based on network＇s oerforrnance are supplide.
