             Packet Loss Signaling for Encrypted Protocols
                draft-ferrieuxhamchaoui-quic-lossbits-03

Abstract

   This document defines an extension to the QUIC transport protocol to
   allow endpoints to signal packet loss in a way that can be used by
   network devices to measure and locate the source of the loss.

   Discussion of this work is encouraged to happen on the QUIC IETF
   mailing list quic@ietf.org [1] or on the GitHub repository which
   contains the draft: https://github.com/igorlord/draft-
   ferrieuxhamchaoui-lossbits [2].
