Abstract :
A software defined optical network based on multi-level WDM ring topology for intra data center switching is proposed. SDN-based unified control plane as well as the routing strategy are given, which make the control and management flexible. Analytical results show that the multi-level WDM ring network structure has good scalability which can support about 256,000 servers under the assumption of each server allocating 1 Gbps bandwith without over subscription.
