Real-Time Scheduling of Asynchronous TSN Traffic.

Time sensitive networking (TSN) is a new set of Ethernet standards that provide real-time and security for automotive, aerospace and industrial automation applications. Traffic in time sensitive networks has combination, complexity and flexibility. Due to the differences of devices in the actual network, time synchronization on time sensitive networks is sometimes difficult to achieve. Ensuring latency performance for critical traffic becomes a challenge. To solve this problem, we propose a non-synchronous time sensitive network traffic scheduling model and implement a Flexible window based GCL(FWND) scheduling. Experimental results show that the proposed scheduling method achieves traffic scheduling for non-synchronous TSN networks at the cost of a small worst end to end delay and average bandwidth usage.
