PROTO Write-up

(1.a) Who is the Document Shepherd for this document? Has the
Document Shepherd personally reviewed this version of the
document and, in particular, does he or she believe this
version is ready for forwarding to the IESG for publication?

Nevil Brownlee. I have reviewed this draft, I believe
it is ready to forward to the IESG for publication.

(1.b) Has the document had adequate review both from key WG members
and from key non-WG members? Does the Document Shepherd have
any concerns about the depth or breadth of the reviews that
have been performed?

This is version 3 of the draft, it has had extensive review
by the WG members, and by others from the PSAMP WG.
These reviews seem sufficiently thorough to me.

(1.c) Does the Document Shepherd have concerns that the document
needs more review from a particular or broader perspective,
e.g., security, operational complexity, someone familiar with
AAA, internationalization or XML?

The draft is concerned only with specifying an effective way
to export bidirectional flow information using IPFIX.
However, because bidirectional flows are used in other
areas, e.g. IPPM, we elieve this draft should go to IETF
Last Call.

(1.d) Does the Document Shepherd have any specific concerns or
issues with this document that the Responsible Area Director
and/or the IESG should be aware of? For example, perhaps he
or she is uncomfortable with certain parts of the document, or
has concerns whether there really is a need for it. In any
event, if the WG has discussed those issues and has indicated
that it still wishes to advance the document, detail those
concerns here. Has an IPR disclosure related to this document
been filed? If so, please include a reference to the
disclosure and summarize the WG discussion and conclusion on
this issue.

There are no specific concerns for this document.

(1.e) How solid is the WG consensus behind this document? Does it
represent the strong concurrence of a few individuals, with
others being silent, or does the WG as a whole understand and
agree with it?

This document has strong consensus within the IPFIX
Working Group.

(1.f) Has anyone threatened an appeal or otherwise indicated extreme
discontent? If so, please summarise the areas of conflict in
separate email messages to the Responsible Area Director. (It
should be in a separate email because this questionnaire is
entered into the ID Tracker.)

No.

(1.g) Has the Document Shepherd personally verified that the
document satisfies all ID nits? (See
http://www.ietf.org/ID-Checklist.html and
http://tools.ietf.org/tools/idnits/). Boilerplate checks are
not enough; this check needs to be thorough. Has the document
met all formal review criteria it needs to, such as the MIB
Doctor, media type and URI type reviews?

Idnits tool Version: 2.03.12 found no nits.
The draft is IPFIX-centric, it needs no other formal checks.

(1.h) Has the document split its references into normative and
informative? Are there normative references to documents that
are not ready for advancement or are otherwise in an unclear
state? If such normative references exist, what is the
strategy for their completion? Are there normative references
that are downward references, as described in [RFC3967]? If
so, list these downward references to support the Area
Director in the Last Call procedure for them [RFC3967].

Yes and yes. This draft depends on the IPFIX Protocol and IPFIX
Info Mode; these drafts are held up waiting for the PSAMP drafts.
The PSAMP editors/authors have spent the last six months or more
working on the IPFIX documents - those are now (nearly) complete,
so they will now work on PSAMP. We expect the PSAMP documents to
be submitted to IESG within about three months.

(1.i) Has the Document Shepherd verified that the document IANA
consideration section exists and is consistent with the body
of the document? If the document specifies protocol
extensions, are reservations requested in appropriate IANA
registries? Are the IANA registries clearly identified? If
the document creates a new registry, does it define the
proposed initial contents of the registry and an allocation
procedure for future registrations? Does it suggest a
reasonable name for the new registry? See [RFC2434]. If the
document describes an Expert Review process has Shepherd
conferred with the Responsible Area Director so that the IESG
can appoint the needed Expert during the IESG Evaluation?

This draft has an IANA Considerations section, because it
requires IANA to allocate a Private Enterprise Number for
the 'reverse direction' information elements. IANA have
been asked to set up the private enterprise number registry
in the IPFIX Information Model draft; Michelle Cotton of
IANA is mentioned in the Acknowledgements section for her
help with this.

(1.j) Has the Document Shepherd verified that sections of the
document that are written in a formal language, such as XML
code, BNF rules, MIB definitions, etc., validate correctly in
an automated checker?

Yes, I've checked the draft's XML (Appendix B).

(1.k) The IESG approval announcement includes a Document
Announcement Write-Up. Please provide such a Document
Announcement Write-Up? Recent examples can be found in the
"Action" announcements for approved documents. The approval
announcement contains the following sections:

Technical Summary

This document describes an efficient method for exporting bidirectional
flow (Biflow) information using the IP Flow Information Export (IPFIX)
protocol, representing each Biflow using a single Flow Record.

Working Group Summary

The working group considered several methods of encoding bidirectional
flow data, these are discussed in the document, as well as the method
which was chosen. The Working Group has reached consensus on this
document.

Document Quality

This document has been reviewed by by the IPFIX Working Group Chairs.

The following note was sent by the document shepherd Nevil Brownlee:

Although these ('biflows ' and 'reducing redundacy') drafts are both informational rather than standards track, I'd like them to go through an IETF Last Call, since the IPFIX meeting on Tuesday showed that although we have strong WG consensus, there are some differing opinions, particaularly on biflows.
