The architecture design and application of IP SDN controller system

In the era of SDN/NFV technology, in order to meet the goal of cloud network convergence and cloud digital transformation, this paper proposes an IP SDN controller architecture design and implementation scheme. According to the characteristics of loose coupling and flexible deployment of each module, the system architecture of IP SDN controller is designed to realize the decoupling of four layers: application layer, service abstraction layer, core network function layer and protocol adaptation layer. In addition, as a common module, the plug-in development platform of the controller provides the micro-service governance, plug-in framework, continuous integration and continuous delivery tool chain involved in the above four layers. Through key capability research and development, deployment and implementation verification and technical standardization, IP SDN controller, as the core capability base of a new generation of cloud network operation system, enables cloud network integration.
