[Ballot discuss]
Please write substantive congestion control considerations.  RFC 3985, the PW architecture,
included an agreed on congestion avoidance procdure for PWs that can't
change their rates (inelastic), such as CBR.  This was to shut off for some
period once they measure a certain level of loss, IFF they are in a best-effort PSN.
This is found in Section 6.5, paragraph three.  I think the Congestion Control Considerations
needs to say something like:  a CBR PW  SHOULD be run over traffic-engineered systems
providing it AF (minimal loss, low impact on other streams) or better, to avoid risk
of congestion on the PSN and the service, or it SHOULD perform the loss monitoring
described in RFC 3985, section 6.5 and when the loss is higher than a threshold,
shut itself down for some waiting period determined to avoid congestion pulses.

I suspect it should be (i.e not 18, 26 and 34, but 10, 20 and 30):

same to other figures (page 6 and 7)

Page 8:
  RSV (reserved) and FRG (fragmentation) bits (6 to 10) - MUST be set to
  0 by the PSN-bound IWF and MUST be ignored by the CE-bound IWF.
probably change "(6 to 10)" into "(6 to 9)" to be in sync with figure 3!

[Ballot comment]
there are two sequence number mechanisms: the control word and the RTP
sequence number mechanism.  One MAY be used; the other is used.  That
seems confusing.  Why not require one and forbid the other or at least
explain why both are permitted.

I came very close to holding a discuss because I found it difficult to
evaluate whether the TDM control protocol will be able to set up all
the configuration parameters for this document.  I would recommend
having a section that specifies in one place all the things that need
to be configured for this type of PW to work.  That would make
reviewing this document independent of the TDM control document
easier.  I may hold discusses on similar issues in the future.

Reference problem spotted by Gen-ART reviewer Elwyn Davies.

Draft section 4.3.1 cites a non-existent section of RFC 3985 in a way that seems normative, even though 3985 is Informational.

"Bits 0 to 3 MUST be set to 0 as described in [PWE3-ARCH], Section 5.4.4"

It seems the reference should be Normative and to draft-ietf-pwe3-cw-06.txt
(recently approved for PS).

Given the use of RTP, I expected the security considerations to

  appropriate or not to provide the "encryption, integrity, and

  structure shown in fFigure 2b is used.

PROTO QUESTIONAIRRE

1) Have the chairs personally reviewed this version of the ID and do
  they believe this ID is sufficiently baked to forward to the IESG
  for publication?

  Yes

2) Has the document had adequate review from both key WG members and
  key non-WG members? Do you have any concerns about the depth or
  breadth of the reviews that have been performed?

  Yes. In addition to WG review, this design has received extensive
  review in other standards bodies. See Question 9

3) Do you have concerns that the document needs more review from a
  particular (broader) perspective (e.g., security, operational
  complexity, someone familiar with AAA, etc.)?

  No

4) Do you have any specific concerns/issues with this document that
  you believe the ADs and/or IESG should be aware of? For example,
  perhaps you are uncomfortable with certain parts of the document,
  or whether there really is a need for it, etc., but at the same
  time these issues have been discussed in the WG and the WG has
  indicated it wishes to advance the document anyway.

  I would draw your attention to section 8 - congestion control,
  which may draw some comment from the transport ADs. If there
  is an issue in this regard, The text in section 10.1 of
  draft-ietf-ipfix-protocol-16.txt may, form the basis of a
  suitable compromise.

5) 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?

  There is strong consensus for this design.

6) Has anyone threatened an appeal or otherwise indicated extreme
  discontent?  If so, please summarize what are they upset about.

  No

7) Have the chairs verified that the document adheres to _all_ of the
  ID nits?  (see http://www.ietf.org/ID-nits.html).

  Pwe3 Status Pages says it has no nits

8) Does the document a) split references into normative/informative,
  and b) are there normative references to IDs, where the IDs are not
  also ready for advancement or are otherwise in an unclear state?
  (Note: the RFC editor will not publish an RFC with normative
  references to IDs, it will delay publication until all such IDs are
  also ready for publication as RFCs.)

  a) yes

  b) No
