RTP Burst Measurements Need the Network and the Playout Buffer in the Same Report
Packet timing only becomes actionable when it is tied to endpoint tolerance.
The bench evidence for RTP Burst Measurements Need the Network and the Playout Buffer in the Same Report forced a narrower explanation than the original assumption. The LOUP lab observed burst structures around 80 milliseconds and gaps extending above 150 milliseconds while overall loss remained low.
Network capture alone says when packets arrived; firmware logs say whether the jitter buffer absorbed the disturbance. Reading both lets us distinguish a network event the endpoint handled from one that actually reached the speaker.
Verification included both the happy path and the failure path because a feature that works once is not yet a production contract. Evidence marker: rtp-burst-measurement.
Network quality should be evaluated against application tolerance, not only against generic loss and latency thresholds. For a voice product, that kind of boundary discipline matters because audio, signalling and hardware symptoms often look deceptively similar.
