RFC 9368
Title: Compatible Version Negotiation for QUIC
Author: D. Schinazi,
E. Rescorla
Status: Standards Track
Stream: IETF
Date: May 2023
Mailbox: dschinazi.ietf@gmail.com,
ekr@rtfm.com
Pages: 15
Updates: RFC 8999
I-D Tag: draft-ietf-quic-version-negotiation-14.txt
URL: https://www.rfc-editor.org/info/rfc9368
DOI: 10.17487/RFC9368
QUIC does not provide a complete version negotiation mechanism but
instead only provides a way for the server to indicate that the
version the client chose is unacceptable. This document describes a
version negotiation mechanism that allows a client and server to
select a mutually supported version. Optionally, if the client's
chosen version and the negotiated version share a compatible first
flight format, the negotiation can take place without incurring an
extra round trip. This document updates RFC 8999.
This document is a product of the QUIC Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
