Based on the Cloud Data Center Optical Switching Scheduling and Routing Algorithm Research and Practice

The trend of diversification, convenience and scale development of cloud services brings new challenges to the optimization of network performance of data centers. This paper around the exchange of data center network performance optimization scheduling and routing algorithm design problems put forward two based on the Input Queue (IQ: Input Queue) optical switching scheduling algorithm of SDF (Stringent Delay First) and m - SDF (m - order Stringent Delay First). Study two data center network models: multiple independent data center network mi-dcn (Multiple Independent DCN) and Integrated Distributed DCN. The concept of Software Defined Network (SDN) is introduced into the data center, and the transmission routing algorithm is designed to realize load balancing of data center resources.
