Coding for QUIC

Tue, 05/26/2020 - 12:17 by François Michel


This document focuses on the integration of FEC coding in the QUIC
transport protocol, in order to recover from packet losses. This
document does not specify any FEC code but defines mechanisms to
negotiate and integrate FEC Schemes in QUIC. By using proactive loss
recovery, it is expected to improve QUIC performance in sessions
impacted by packet losses. More precisely it is expected to improve
QUIC performance with real-time sessions (since FEC coding makes
packet loss recovery insensitive to the round trip time), with short
sessions (since FEC coding can help recovering from tail losses more
rapidely than through retransmissions), with multicast sessions
(since the same repair packet can recover several different losses at
several receivers), and with multipath sessions (since repair packets
add diversity and flexibility).
