Abstract

QUIC does not provide a complete version negotiation mechanism butinstead only provides a way for the server to indicate that theversion the client chose is unacceptable. This document describes aversion negotiation mechanism that allows a client and server toselect a mutually supported version. Optionally, if the client'schosen version and the negotiated version share a compatible firstflight format, the negotiation can take place without incurring anextra round trip. This document updates RFC 8999.
