With the development of the new generation of information network technology and the massive data integration generated by the Internet of Everything, the management planning of data is becoming more and more reasonable. The data management plane is configured and issued to the data service plane, which can meet the data transmission requirements of different application scenarios. Most network configurations need to be performed during network downtime or when the device is offline, which makes it difficult to meet the requirements for application scenarios such as industrial control. Time- sensitive network (TSN) introduces centralized network configuration (CNC) and centralized user configuration (CUC) through IEEE 802.1Qcc to realize the dynamic configuration of the network and flexibly configure new devices and data flows when the network is running. This paper designs a centralized time-sensitive network controller cluster system to configure the resources of the data service plane of time-sensitive network devices, optimize the resource utilization of the network, and realize flexible networking of the network; based on the distributed cluster technology characteristics of the ONOS open source controller, the network controller is designed and deployed with high reliability, and the controller fault tolerance and elasticity mechanism are realized to solve the reliability problem caused by the single point failure of the TSN network controller.
