Track Switching Made Easy in Media-Over-Quic Transport

As the Media-over-QUIC Transport (MOQT) continues to evolve, interest in its potential as a versatile media delivery protocol capable of scaling efficiently and operating at sub-second latencies is growing. In this paper, we propose an atomic operation for track switching between alternative tracks in media streaming, enhancing the current SUBSCRIBE/UNSUBSCRIBE mechanism of MOQT. Further, we present results from our implementation of the method that show significant reductions in excess traffic that would normally lead to unnecessary stalls during track switching.
