摘　　要：随着密集型应用和高性能计算的发展,近些年来有越来越多针对数据中心网络的网络构架、可伸缩性、流量优化和成本效益等方面的研究。为了比较和分析不同网络拓扑结构之间的差异,文章通过使用Qualnet网络仿真软件按照数据中心网络的流量特点来实现对多层网络和Fat tree网络拓扑的仿真模拟,并设置节点失效状况,来对容错性进行分析,评估其网络性能。With the development of intensive and high performance computing,in recent years there are more and more study on data center network which aiming at its architecture,scalability,throughput optimization and cost-benefit.In order to compare and analyze the differences performance of between different network topologies,this paper follow the traffic characteristics of Data Center Networks to perform the simulation of multi-layer network and Fat tree network topology by using QUALNET Network Simulator,and also set the node failure condition,to the analysis of fault-tolerant,evaluating the network performance.
