Performance evaluation of datacenter network topologies with link failures

Data centers are experiencing tremendous growth in the number of servers and networking devices with an increase in traffic to cloud infrastructures. Data center network (DCN) topology plays an important role in providing acceptable level of performance to cloud applications. This paper presents the results of a simulation studies comparing the performance of several well-known DCN topologies under the same simulation and inter-network traffic workload environments. We also present the performance results for the network topologies when a link or a switch in the network fails.
