QUIC M. Thomson Internet-Draft Mozilla Intended status: Standards Track 15 January 2021 Expires: 19 July 2021 Version-Independent Properties of QUIC draft-ietf-quic-invariants-13 Abstract This document defines the properties of the QUIC transport protocol that are common to all versions of the protocol.

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. Thomson Expires 19 July 2021 [Page 2] 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.Show full document text
