The Research of SDN Group Policy Model Based on Application Centric Environment

In recent years, SDN develops rapidly all around the world, known as a great renovation for the traditional network architecture. SDN principle advantages contain separation of hardware and software, separation of control and management, centralized management, open source, bringing low cost, high efficiency and flexible business. Power Grid has complicated application system, and data center is the most important, so introducing SDN can build a better IT infrastructure to supply application services. In order to drive network through application and enhance the convenience of application deployment and maintenance in datacenter, this paper presents a SDN group policy model with application centric. Firstly, a universal SDN based environment is developed, and the server physical location, security strategy and network address IP are decoupled by introducing and extending VXLAN technology. Secondly, combined with the grid application, a group policy control method is described in detail. The introduced SDN group policy control model will enhance the SDN centralized management and control functions, and simplify the network application deployment and maintenance.
