=== 1. Summary ===
Document shepherd: Nevil Brownlee
Responsible Area Director: Benoit Claise
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

=== 2. Review and Consensus ===
This draft was written by Brian Trammell and Paul Aitken, both of whom

Braun made further contributions to the discussion; in particular
noting that backward compatibility with existing IPFIX collectors must
The draft has been discussed on the IPFIX list since early September;

Brian acknowledges that this work on this is partially supported by
the mPlane project, implying that there is strong interest in it
=== 3. Intellectual Property ===
There are no IPR disclosures for this draft. Since it's simply
updating an Information Element to match current - i.e. later than
RFC 793 - Internet Standards, I can't believe anyone could claim
IPR on it!
=== 4. Other Points ===
This document does not have any downward references.
Its IANA Considerations simply ask IANA to change the tcpControlBits
Information Element (IE) in the IE Registry, following the process
described in RFC 7012. This is a simple, clearly-defined change.
The ID-nits checker complains that some of its references are drafts
that have been published as RFCs; the RFC Editor will fix those.
Overall, I believe that this draft is ready for publication as
