The IESG has approved the following document: - 'Revision of the tcpControlBits IPFIX Information Element' (draft-trammell-ipfix-tcpcontrolbits-revision-05.txt) as Informational RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-trammell-ipfix-tcpcontrolbits-revision/ 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.
