Abstract:In order to dynamically assign the optical/electrical routing path and optimize the optical/electrical resource allocation, a software-defined hybrid optical/electrical data center architecture (SD-HDC for short) is proposed in this work. A control mechanism that consists of two parallel steps including the new request handle step and the hybrid resource optimize step is introduced in SD-HDC. The new request handle step is used to quickly process the new incoming request while the hybrid resource optimize step periodically optimizes the hybrid optical/electrical network resource. To validate the SD-HDC architecture, a hybrid optical/electical routing algorithm used for handling elephant/mice flows is also proposed in this paper. Experimental results show that the proposed SD-HDC architecture can effectively reduce the blocking probability and path provisioning latency.
