A Hybrid Electrical and Optical Networking Topology of Data Center for Big Data Network

Now-a-days data centers are experiencing rapid increase in network traffic and the number of servers in racks due to exponential increase of data, at the same time they have to cope with the demands of cloud computing and several emerging web applications. Keeping all these in mind we also have to consider compatibility when we will interconnect several data centers. Present data centers network based on electrical packet switching consumes much power and has bottleneck issues. Several researches in optical fiber have made it possible to use optical circuit switch in data centers which provides promising solution offering high bandwidth, low latency, incredibly less power consumption. In this paper we present a possible bottom to top electrical and optical packet switch architecture of data centers and interconnectivity solution between them. Furthermore we propose two networks interconnects: an optical circuit switch (OCS) handling long-lived bulk data transfer using optical network and a secondary lower bandwidth electronic packet switch (EPS) network for handling short data transfer.
