Design and implementation of SDN controller platfom

Innovation networking technology led to the traditional TCP / IP network towards a more high-speed, open, intelligent direction. Based on the theory of SDN and the open-source controller, developed a four-tier structure SDN control platform, respectively, to achieve and maintain the connection is established, the message adaptation, application interface and other functions. Design and implement adaptation layer message to the device management module, event distribution module, message encapsulation module gives the detailed design and implementation, the news distribution mechanism design based on finite buffer queue on core control plane, the message encapsulation module, OpenFlowl.3 agreement gives several messages (port information modify the message, modify the message flow table entries, meter entries modify the message) encapsulation process.
