A SDN-Based Hybrid Electrical Optical Architecture

As the high-bandwidth and data-intensive applications evolving rapidly, traditional electrical networks are no longer able to meet the increasing traffic requirements. In order to improve the communication performance of data center network(DCN), the hybrid electrical/optical architecture has become a new research topic. Moreover, traditional architectures are often too complicate to manage. As a new technology, Software Defined network (SDN) addresses this issue effectively. In this paper, we propose a hybrid architecture based on SDN. The control manager is used to monitor and allocate traffic, then configure the network by SDN. There is a hybrid network platform under the implementation of virtual machine migration. The experiment shows that the proposed scheme reduces the total time of the virtual machine migration effectively compared to that running on the electrical architecture. In addition, our scheme can configure the network topology flexibly and achieve load balancing.
