Abstract:
Exponential growth of traffic and bandwidth demands in current data center networks, requires low-latency high-throughput interconnection networks, considering power consumption. Furthermore, increasing multicast intensive applications, alongside conventional unicast applications, arises power efficient communication in today’s data center networks as the main design challenge. Addressing these demands, optical networks suggest several benefits as well as circumventing most disadvantages of electrical networks. In this thesis, we propose an all-optical scalable architecture, for communicating intra-data centers. This architecture utilizes passive optical devices and enables optical circuit switching without any switch configuration or path reservation. In addition, it is customized for both unicast and multicast transmissions. It can replace aggregation and core switches in the network, to reduce power consumptions. Simulation results verify its lower latency, higher throughput, and reduced power consumption, compared to conventional electrical or alternative optical solutions
