Technical Summary
This document revises the tcpControlBits IPFIX Information Element
defined in RFC 5102 to reflect changes to the TCP Flags header field
since RFC 793. Since RFC 5102 is a Proposed Standard RFC, a change to
one of its Information Elements requires IETF consensus.
The document is Informational; it provides information to IPFIX
developers who wish to use TCP's ECN-related flag bits.
Working Group Summary
The draft has been discussed on the IPFIX list since early September;
there is clear consensus for it within the WG.
This document is AD-sponsored as the IPFIX WG is slowly but surely
finishing up his last deliverables and will be shutting down.
Document Quality
This draft was written by Brian Trammell and Paul Aitken, both of whom
are IE-Doctors and active IPFIX developers. Andrew Feren and Lothar
Braun made further contributions to the discussion; in particular
noting that backward compatibility with existing IPFIX collectors must
be maintained.
Brian acknowledges that this work on this is partially supported by
the mPlane project, implying that there is strong interest in it
within mPlane.
