TSN Frame Preemption Testing: Creating a 'Green Channel' for Data Transmission

Introduction: In complex and dynamic fields such as automotive and industrial control, the timeliness and determinism of data transmission are crucial. In scheduling shaping mechanisms like TAS or CQF, different priority services are mapped to different queues, ensuring that high-priority services are not interfered with by low-priority services during transmission, thus guaranteeing end-to-end low latency … Read more
