Abstract: Empirical field validation of IEEE 802.1Qbv frame preemption preventing high-throughput video surveillance bursts from perturbing sub-millisecond motion control loops.
To validate the deterministic properties of RealWorldControl, an industrial testbench was configured with isolated multi-core hardware, real-time Linux kernel patches, high-precision oscilloscope probe taps, and TSN network traffic generators injecting packet bursts up to full 10 Gbps line rate.
Over 100 million execution cycles, the maximum observed scheduling jitter for RealWorldControl remained constrained within sub-5 microsecond bounds. Even under severe CPU cache thrashing and simultaneous DMA storage transfers, zero deadline violations occurred across critical control threads.
Deploying RealWorldControl in production facilities requires adhering to validated hardware qualification checklists, including disabling CPU power-saving C-states, configuring isolated hugepages, and establishing automated regression suites via continuous hardware-in-the-loop (HIL) automation.
