1.  Introduction

   QUIC [QUIC-transport] is a transport protocol that aims at improving
   network performance by enabling stream multiplexing, partial
   reliability, and methods of recovery besides retransmission, while
   also improving security.  This document specifies FEC schemes for
   Sliding Window Random Linear Code (RLC) [RFC8681] to recover from
   lost packets within a single QUIC stream or across several QUIC
   streams, compliant with the FEC coding framework for QUIC
   [Coding4QUIC].

   The ability to add FEC coding in QUIC may be beneficial in several
   situations:

   o  for a robust transmission of latency-sensitive traffic, for
      instance real-time flows, since it enables to recover packet
