针对多层网络和Fat tree网络的仿真研究

Simulation Research on Multilayer Network and Fat Tree Network

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.
