The rise of Cloud Computing and Big Data has created the need for morepowerful warehouse-scale cloud data centers,which usually comprise hundreds of thousands ofservers with highaccess bandwidth(>10Gb/s)or more,and cost-effective intra-and interdata center networks(DCNs)to provide switching and interconnect among all servers.However,the current DCNs sufferfrom limited throughput,large latencies and highpower consumption,and will not be able to sustainthe projected future DCN traffic demandswithout consuming excessive amounts of power.Optical
The rise of Cloud Computing and Big Data has created the need for more powerful warehouse-scale cloud data centers, which usually include hundreds of thousands of servers with highaccess bandwidth (> 10 Gb / s) or more, and cost-effective intra-and interdata center networks (DCNs) to provide switching and interconnect among all servers. Host, the current DCNs suffer from limited throughput, large latencies and highpower consumption, and will not be able to sustainthe projected future DCN traffic demandswithout consuming excessive amounts of power.
