Spirent TTsuite‑TSN‑FilteringAndPolicing, now part of VIAVI, tests conformance of automotive, industrial, and telecom devices to IEEE 802.1Qci per‑stream filtering and policing standards. It verifies flow meter behavior, including bandwidth handling and enforcement of committed and excess information rates. The suite evaluates both reception and transmission at different traffic rates to ensure proper supervision, filtering, and policing of individual streams. By validating compliance with IEEE 802.1Qci‑2017, it helps ensure that devices reliably manage traffic shaping and protection in time‑sensitive networking environments.
