Network Traffic Scheduling Based on SDN in Cloud Data Center

Xin Cui, Lianjun Zhao, Zhen Cheng


In order to realize dynamic load balancing based on data stream level, SDN technology is applied to cloud data center, and based on SDN of the cloud center dynamic load equilibrium method. The method utilizes SDN Technology in the flow and task scheduling flexibility on the advantages of adoption OpenFlow Protocol on the service node traffic and load conditions real-time monitoring. When the system load imbalance occurs, the controller can be deployed in the global network resource load, through more accurate dynamic correction to ensure that the system in the long run the load will not be significantly tilted. Simulation experiments show that this method realizes and ensures that the load does not tilt for a long time, and can improve the system throughput.
