draft-pauly-quic-datagram-05
Abstract
This document defines an extension to the QUIC transport protocol to
add support for sending and receiving unreliable datagrams over a
QUIC connection.
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/tfpauly/draft-pauly-quic-

1. Introduction
The QUIC Transport Protocol [I-D.ietf-quic-transport] provides a
secure, multiplexed connection for transmitting reliable streams of
application data. Reliability within QUIC is performed on a per-
stream basis, so some frame types are not eligible for
retransmission.
Some applications, particularly those that need to transmit real-time
data, prefer to transmit data unreliably. These applications can
build directly upon UDP [RFC0768] as a transport, and can add
security with DTLS [RFC6347]. Extending QUIC to support transmitting
unreliable application data would provide another option for secure
datagrams, with the added benefit of sharing a cryptographic and
authentication context used for reliable streams.
This document defines four new DATAGRAM QUIC frame types, which carry
application data without requiring retransmissions.

mailing list quic@ietf.org [3] or on the GitHub repository which
