The Time-Sensitive Networking (TSN) working group has introduced a comprehensive set of standards to enable reliable communication in time-critical systems. The TSN standards set encompasses several shaping mechanisms that aim to provide bounded transmission latency for streams in the network. Among these shaping mechanisms, Cyclic Queuing and Forwarding (CQF) and frame preemption provide deterministic guarantees for frame transmission. However, despite some current studies on the performance analysis of CQF and frame preemption, they also need to consider the potential effects of their combined usage on frame transmission. Furthermore, there is a need for more research that addresses the impact of parameter configuration on frame transmission under different situations and shaping mechanisms, especially in the case of mechanism combination.
