Key result
Hardware characterization calibrates simulated TSN switches to closely match actual performance.
Why the study?
Time-Sensitive Networking introduces complexity requiring study via simulation, but ensuring simulation behavior matches hardware requires validation.
The paper characterizes the behavior of a TSN switch to calibrate a simulated switch, ensuring simulation behavior closely matches hardware.

Calibration supports TSN simulator fidelity in research; leaves open clinical network validation.
To meet the new needs of deterministic networks, the IEEE has proposed an extension to Ethernet called Time-Sensitive Networking (TSN). Among other things, this extension makes it possible to achieve low latency performance with availability equivalent to or better than current solutions, to unify high-speed networks and real-time field buses, and is based on open, multi-industry standards. Nevertheless, this extension introduces a certain complexity (e.g. interaction between mechanisms, search for the optimal configuration, ...) which needs to be studied. To achieve this goal with a low investment in time and hardware, simulation is the ideal tool. But for the results to be meaningful, we need to ensure that the simulation behavior is close to that of the hardware. So in this paper, we characterize the behavior of a TSN switch and use these characterization results to calibrate the behavior of a simulated switch.

Q Bailleul (2026) studied Time-Sensitive Networking (TSN) simulation. TSN simulator calibration vs. Hardware measurements was evaluated on Simulation behavior compared to hardware. Characterization of a TSN switch's hardware behavior was used to calibrate a simulated switch to ensure simulation results closely match hardware performance.
