一种基于NETCONF的TSN网络配置方法

A Network Configuration Method of TSN Based on NETCONF

时间敏感网络的手动配置方法不能满足制造业IT和OT网络不断融合的发展趋势,同时,实时控制和机器视觉等应用对带宽、延迟、抖动等服务质量需求的不断提升。基于NETCONF网络配置协议,提出了自动收集网络拓扑信息和流量需求进行TSN自动配置的方法,能够自动适应网络拓扑和流量需求的改变。阐述了基于集中式网络配置实体CNC、集中式用户配置实体CUC的集中式网络配置架构和自动配置方法,并通过原型系统实现和测试验证了该方法的有效性。

The manual configuration method of Time Sensitive Network cannot meet the trend of continuous convergence of IT and OT networks in manufacturing industry and the increasing demand for bandwidth,delay,jitter and other quality of service for applications such as real-time control and machine vision.Based on the NETCONF protocol,a method to automatically collect network topology information and traffic QoS requirements for TSN auto-configuration was proposed,which can automatically adapt to the change of network topology and traffic QoS requirements.A centralized network configuration architecture and an automatic configuration method based on centralized network configuration(CNC)and centralized user configuration(CUC)are described,and the effectiveness of the method is verified through prototype system implementation and testing.
