Congestion control for real-time media over QUIC
Mathis Engelbart, Jörg Ott · 2021
QUIC is the new transport protocol for the Internet, designed for secure, reliable communication, especially with the web in mind. While multimedia streaming, allowing for some playout delay, has been widely run on top of reliable transport protocols, conversational multimedia usually requires unreliable ones, often using RTP over UDP. A recent extension to QUIC supports unreliable datagrams within QUIC connections so that also real-time media can be supported. In this paper, we investigate a recent design for RTP over QUIC with a focus on congestion control and the related signaling. We implement a strawman using Gstreamer and quic-go and evaluate different permutations of congestion control algorithms and signaling in a simple testbed.
