Greasing the QUIC Bit <del> draft-ietf-quic-bit-grease-latest </del> Abstract This document describes a method for negotiating the ability to send <del> an arbitrary value for the second-to-most significant bit in QUIC </del> <ins> an arbitrary value for the second-most significant bit in QUIC </ins> packets. 1. <del> QUIC QUIC intentionally describes a very narrow set of fields that are visible to entities other than endpoints.  Beyond those characteristics that are defined as invariant QUIC-INVARIANTS, very little about the "wire image" RFC8546 of QUIC is visible. </del> <ins> The version-independent definition of QUIC QUIC-INVARIANTS intentionally describes a very narrow set of fields that are visible to entities other than endpoints.

The purpose of having a fixed value is to allow endpoints to efficiently distinguish QUIC from other protocols; see DEMUX for a

Where endpoints and the intermediaries that support them do not depend on the QUIC Bit having a fixed value, sending the same value <del> in every packet is more of liability than an asset.  If systems come to depend on a fixed value, then it might become infeasible to define a version of QUIC that attributes semantics to this bit. </del> <ins> in every packet is more of a liability than an asset.

The transport parameter is sent with an empty value; an endpoint that understands this transport parameter MUST treat receipt of a non-empty value of the transport parameter as a connection error of type TRANSPORT_PARAMETER_ERROR. </del> <ins> The grease_quic_bit transport parameter (0x2ab2) is defined for QUIC version 1 QUIC.  This transport parameter can be sent by both client and server.  The transport parameter is sent with an empty value; an endpoint that understands this transport parameter MUST treat receipt of a non-empty value of the transport parameter as a connection error of type TRANSPORT_PARAMETER_ERROR. </ins> An endpoint that advertises the grease_quic_bit transport parameter MUST accept packets with the QUIC Bit set to a value of 0.

A server MUST NOT remember that a client negotiated the extension in a previous connection and set the QUIC Bit to 0 based on that information.
