MoQ Probe Extension rev 00 lands on the IETF Datatracker
This document defines a PROBE extension for MoQ Transport [moqt]. A subscriber opens a bidirectional PROBE stream to request that the publisher pad the connection up to a target bitrate. The publisher sends padding as defined in [moqt] Section 7.7 and periodically responds with the measured bitrate and an elapsed timestamp, enabling the subscriber to estimate the available bandwidth.
