TSNPerf generates deterministic multi-stream 802.1Q traffic, measures one-way latency at microsecond resolution, and presents live results in a clean browser dashboard — all from a single binary, no installation required.
Independent loss, latency, and jitter statistics for every VLAN traffic class in a single run.
Structured export with full statistics and per-stream results for automated regression tracking.
Simultaneous VLAN/PCP traffic classes with isolated loss and latency tracking per stream.
Real Ethernet frame tagging — EtherType 0x8100, correct PCP bits readable by TSN switches.
One-way latency measured at microsecond resolution with min, max, average, and jitter.
Windows x86_64, Linux x86_64, and BeagleBone Black / ARMv7 — same behavior everywhere.
From quick bench checks to full multi-stream qualification runs — TSNPerf handles the entire workflow in one self-contained tool with no installation or runtime dependencies.
Transmit up to 8 VLAN and PCP traffic classes simultaneously, each with its own rate controller and TSN cycle gate — in a single command.
One-way latency is computed as receive timestamp minus embedded send timestamp. Min, max, average, and RFC 3550 jitter reported per stream.
Raw Ethernet mode sends genuine IEEE 802.1Q tagged frames with EtherType 0x8100 and correct PCP bits — readable by TSN switches and analyzers.
Model 802.1Qbv gate control behavior with configurable cycle duration and gate-open slot width. Timing values in microseconds, milliseconds, or seconds.
Start an embedded web dashboard directly from the receiver. Open any browser on the same network — no frontend installation, no separate process.
Export complete results as JSON — overall statistics plus detailed per-stream breakdowns — ready for automated comparison, CI pipelines, and regression tracking.
TSNPerf fits both quick bench checks and longer automated validation runs on real TSN hardware.
Single pre-built binary for your platform. No installation, no runtime dependencies — copy and run.
Set VLAN IDs, PCP values, packet rate, payload size, TSN cycle timing, and stream combinations for your test case.
Run the receiver first — it waits for traffic. Start the sender with your configuration. Results appear in real time.
Inspect the live dashboard in your browser, then save the full JSON report for documentation or automated comparison.
Download TSNPerf and run immediately. The evaluation period starts from first launch. All core features work within the trial limits so you can validate the tool on your real hardware before purchasing.
The trial gives you full access to every feature within these boundaries. A license removes all limits.

Single self-contained binary — no installation, no runtime dependencies. Copy to your device and run. Each platform has a standard UDP build and a raw Ethernet build.
Runs on Windows 10 / 11 (64-bit). Raw Ethernet mode requires Npcap installed and Administrator privileges.
