In a software-defined zonal vehicle, a single multi-gigabit Ethernet backbone carries raw LiDAR point clouds, infotainment video, and critical brake actuation. Without deterministic queue control, bursty video packets delay safety-critical actuation.
Each TSN switch implements 8 priority egress queues per port governed by a transmission selection algorithm. By representing link propagation delays, bridge processing jitter, and serialization latency as linear constraints in an SMT model, the synthesis engine derives exact gate opening timestamps for every stream.
Vehicle network topologies change dynamically when features are updated or link faults occur. Advanced centralized network controllers (CNC) execute incremental re-synthesis algorithms, updating Gate Control Lists over NETCONF/YANG without disrupting ongoing ASIL-D traffic streams.
