Title:
METHOD FOR IMPLEMENTING AND EVALUATING TSN TRAFFIC SCHEDULING
Document Type and Number:
WIPO Patent Application WO/2023/163372
Kind Code:
A1
Abstract:
A time-sensitive network (TSN) standardized, maintained, and managed by IEEE 802.1 task group improves the real-time and deterministic capabilities of Ethernet. However, traffic scheduling has not been standardized, and is being widely studied. Most research is essentially theoretical, and there are few practical verifications/research. In order to fill such a gap, the present invention provides detailed instructions for constructing an actual TSN-based process automation system first and regarding how a traffic scheduling method (TSM) will be distributed to industrial facilities.The present applicants empirically investigated the validity of a method according to the present invention and compared the performance thereof with that of a commercial TSN scheduler. The result shows that the method according to the present invention accurately schedules traffic such that robust real-time requirements are satisfied, and removes queuing delay, thereby accomplishing ultra-low latency. The time taken to calculate scheduling with regard to 500 random cases shows that the TSM can appropriately schedule the flow in a millisecond unit at least 571 times faster than a commercial scheduler.
