Study of flow streams as a performance parameter for data centers

In this paper, we present a new data center topology using new components such as top of rack (ToR), switches for the aggregation of each rack, an optical space switches (OSS) using for intra/inter connectivity, and software defined networks (SDN) as control plane for the configuration of network resources. We study the effect of flows streams on the performance of the data centers. Moreover, a comparison between the traditional non-blocking hierarchical network and new network topology all optical in terms of time completion for multicast and unicast flows are presented.
