Compatible Version Negotiation for QUIC
RFC 9368, “Compatible Version Negotiation for QUIC”, is a Proposed Standard document published in May 2023 by D. Schinazi, E. Rescorla. It updates RFC 8999. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
