**TL;DR:** In this paper, the authors apply SDN technology to the cloud data center, and propose a dynamic load balancing method of cloud center based on SDN, which can realize and ensure that the load will not tilt over a long period of time.

## Abstract  
In order to achieve dynamic load balancing based on data flow level, this paper applies SDN technology to the cloud data center, proposing a dynamic load balancing method based on SDN. The approach utilizes SDN technology for current task scheduling flexibility, accomplishing real-time monitoring of the service node flow and load condition via the Open Flow protocol. When the system load is imbalanced, the controller globally allocates network resources. Moreover, through dynamic correction, the system's load remains stable over the long term. Simulation results demonstrate that this approach ensures the load does not tilt over time and improves system throughput.
