With the continuous development of industry, information and intelligence have gradually become the keywords of industrial control. In modern industrial scenarios, more and more devices are connected to the factory network, and the complex network environment will greatly affect the end-to-end transmission performance of key control flows, which brings a huge impact to those high-precision control signal transmissions. With the development of Time Sensitive Network (TSN) in recent years, more and more people have introduced this technology to the field of industrial control. In this paper, we propose a scheduling scheme based on constraint strategy for the key technology of TSN—Time Aware Shaper (TAS). This scheme can derive the appropriate network constraint strategy and optimization scheme of network resource utilization according to the end-to-end Quality of Service (QoS) of multiple key data streams in the network, and finally obtain the configuration scheme of Gate Control Lists (GCLs).
