Hi Wes,

Your suggestion on reserved bits works for me. Thanks.

As we are there are, I suggest to add a second action asking IANA to move the (orphan) TCP flag registry to be a sub-registry under the global “Transmission Control Protocol (TCP) Parameters” (

Also, add to the draft a reminder that “reserved bits” are assigned following Standard Action as per Section 9.2 of RFC 2780.

Hello, this incorporates some small cleanups that accumulated prior to the IETF meeting, as well as some of the feedback received since then on the mailing list.

A couple specific things not yet done (because it doesn't look like we converged on the list yet):

- Did not yet change reserved bits to "unassigned" (nor indicate them in the IANA considerations section).  Rod Grimes has a good point about these being very commonly referred to as "the reserved bits" in other places.  I'm thinking we could add a note to say that in IANA terms they're "Unassigned" to add the clarity that Mohamed is advocating, but not change the name?

- Did not yet move section 2.1.

- Did not yet remove the note about my confusion on MUST vs SHOULD regarding reporting of excessive retransmissions in RFC 1122 (will confirm on the mailing list the "no change" proposal that was suggested at the meeting)

Wesley M. Eddy <><>, Wesley Eddy <><>

A new version of I-D, draft-ietf-tcpm-rfc793bis-14.txt
has been successfully submitted by Wesley M. Eddy and posted to the
IETF repository.

Name: draft-ietf-tcpm-rfc793bis
Revision: 14
Title: Transmission Control Protocol Specification
Document date: 2019-07-30
Group: tcpm
Pages: 104

This document specifies the Internet's Transmission Control Protocol
(TCP). TCP is an important transport layer protocol in the Internet
stack, and has continuously evolved over decades of use and growth of
the Internet. Over this time, a number of changes have been made to
TCP as it was specified in RFC 793, though these have only been
documented in a piecemeal fashion. This document collects and brings
those changes together with the protocol specification from RFC 793.
This document obsoletes RFC 793, as well as 879, 2873, 6093, 6429,
6528, and 6691 that updated parts of RFC 793. It updates RFC 1122,
and should be considered as a replacement for the portions of that
document dealing with TCP requirements. It updates RFC 5961 due to a
small clarification in reset handling while in the SYN-RECEIVED

RFC EDITOR NOTE: If approved for publication as an RFC, this should
be marked additionally as "STD: 7" and replace RFC 793 in that role.

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at
