This paper aims to present a new data center topology using new components such as top of rack (ToR), switches for the aggregation of each rack, optical space switches (OSS) used for intra/inter connectivity, and software defined network (SDN) as control plane for the configuration of the associated network resources. The effect of flows streams is examined further on the performance of the data centers developed into smart cities. Moreover, a comparison between the traditional non-blocking hierarchical network and the proposed new topology all-optical in terms of completion time for multicast and unicast flows are presented.
