1. An Extremely Abstract Description of QUIC
QUIC is a connection-oriented protocol between two endpoints. Those
endpoints exchange UDP datagrams. These UDP datagrams contain QUIC
packets. QUIC endpoints use QUIC packets to establish a QUIC
connection, which is shared protocol state between those endpoints.
2. Fixed Properties of All QUIC Versions
In addition to providing secure, multiplexed transport, QUIC
[QUIC-TRANSPORT] allows for the option to negotiate a version. This
allows the protocol to change over time in response to new
requirements. Many characteristics of the protocol could change
between versions.
This document describes the subset of QUIC that is intended to remain
stable as new versions are developed and deployed. All of these
invariants are IP-version-independent.

Internet-Draft QUIC Invariants January 2021
The primary goal of this document is to ensure that it is possible to
deploy new versions of QUIC. By documenting the properties that
cannot change, this document aims to preserve the ability for QUIC
endpoints to negotiate changes to any other aspect of the protocol.
