Design and implementation of SDN-base QoS traffic control method for Electric power data center network

Abstract

With great of development Electric power data center network, cause to the rapidly increase a amount of data, the rise of a variety of business and a variety of rapid increase of data exchange. Most existing QoS traffic techniques exist many of problems such as Low network resource utilization, bad reliability, poor extensibility and it is difficult to achieve. For the electric power enterprise data center to realize stable and efficient running a challenge, How to make use of the limited network resource effective control network, to ensure that the business service quality of service (QoS) become a pressing problem. This paper proposed an Openlow based QoS traffic method and QoS-ensure method referring to the new idea of separating controlling layer and data layer provided by SDN, which improved flexibility and reliability for QoS control to achieve effective usage of network resources and fine-grained of flow control. The experimental results validated its effectiveness. Through the deployment in Mininet network simulation platform and simulation implementation. The experimental results validated its effectiveness.
