Shepherd writeup
draft-ietf-pwe3-iccp

As required by RFC 4858, this is the current template for the Document
Shepherd Write-Up.

Changes are expected over time. This version is dated 24 February 2012.

(1) What type of RFC is being requested (BCP, Proposed Standard, Internet
Standard, Informational, Experimental, or Historic)? Why is this the proper
type of RFC? Is this type of RFC indicated in the title page header?

Proposed Standard. A new protocol and IANA registry are being defined. Yes.

(2) 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 specifies an inter-chassis communication protocol
   (ICCP) that enables Provider Edge (PE) device redundancy for Virtual
   Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS)
   applications. The protocol runs within a set of two or more PEs,
   forming a redundancy group, for the purpose of synchronizing data
   amongst the systems. It accommodates multi-chassis attachment circuit
   as well as pseudowire redundancy mechanisms.

Working Group Summary:

Was there anything in WG process that is worth noting? For example, was there
controversy about particular points or were there decisions where the consensus
was particularly rough?

There was good consensus on the document, with one exception that is discussed
in the section on IPR. That one exception was the only thing really worth
noting in the process..

Document Quality:

Are there existing implementations of the protocol? Have a significant number
of vendors indicated their plan to implement the specification? Are there any
reviewers that merit special mention as having done a thorough review, e.g.,
one that resulted in important changes or a conclusion that the document had no
substantive issues? If there was a MIB Doctor, Media Type or other expert
review, what was its course (briefly)? In the case of a Media Type review, on
what date was the request posted?

There is at least one shipping implementation "deployed in multiple customer
networks".

Personnel:

Who is the Document Shepherd? Who is the Responsible Area Director?

Andy Malis and Stewart Bryant.

(3) Briefly describe the review of this document that was performed by the
Document Shepherd. If this version of the document is not ready for
publication, please explain why the document is being forwarded to the IESG.

The shepherd conducted a post-WG last call review of -11, which resulted in a
revised -12, which is being submitted here.

(4) Does the document Shepherd have any concerns about the depth or breadth of
the reviews that have been performed?

No.

(5) Do portions of the document need review from a particular or from broader
perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or
internationalization? If so, describe the review that took place.

No.

(6) Describe any specific concerns or issues that the Document Shepherd has
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.

None.

(7) Has each author confirmed that any and all appropriate IPR disclosures
required for full conformance with the provisions of BCP 78 and BCP 79 have
already been filed. If not, explain why?

Yes.

(8) Has an IPR disclosure been filed that references this document? If so,
summarize any WG discussion and conclusion regarding the IPR disclosures.

There was a discussion of IPR that occurred after -09 was uploaded. Cisco
issued an IPR declaration on -09 (see https://datatracker.ietf.org/ipr/1898/ )
that came as a bit of a surprise at that late stage, but it was the result of
an oversight on the part of the authors and nothing nefarious. The IPR claim
was on an optional procedure in the draft, and after discussion by the WG, the
authors revised the draft to remove that particular procedure and replace it
with a different way of getting the same functionality. Thus, that IPR claim no
longer applies to revisions past -09.

(9) 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?

WG consensus is solid.

(10) 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 publicly available.)

No.

(11) Identify any ID nits the Document Shepherd has found in this document.
(See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist).
Boilerplate checks are not enough; this check needs to be thorough.

There is one nit of note, an outdated informational reference: 
draft-ietf-pwe3-redundancy-bit has been published as RFC 6870. This can be
corrected by the RFC Editor. There is also a normative reference to an IEEE
standard that nits complained about.

(12) Describe how the document meets any required formal review criteria, such
as the MIB Doctor, media type, and URI type reviews.

N/A

(13) Have all references within this document been identified as either
normative or informative?

Yes.

(14) 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 plan for their completion?

No.

(15) Are there downward normative references references (see RFC 3967)? If so,
list these downward references to support the Area Director in the Last Call
procedure.

No. As I said above, there is a normative reference to an IEEE standard,

(16) Will publication of this document change the status of any existing RFCs?
Are those RFCs listed on the title page header, listed in the abstract, and
discussed in the introduction? If the RFCs are not listed in the Abstract and
Introduction, explain why, and point to the part of the document where the
relationship of this document to the other RFCs is discussed. If this
information is not in the document, explain why the WG considers it unnecessary.

No.

(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of the
document. Confirm that all protocol extensions that the document makes are
associated with the appropriate reservations in IANA registries. Confirm that
any referenced IANA registries have been clearly identified. Confirm that newly
created IANA registries include a detailed specification of the initial
contents for the registry, that allocations procedures for future registrations
are defined, and a reasonable name for the new registry has been suggested (see
RFC 5226).

The IANA Considerations section is straightforward and meets the criteria in
the question.

(18) List any new IANA registries that require Expert Review for future
allocations. Provide any public guidance that the IESG would find useful in
selecting the IANA Experts for these new registries.

The new "ICC RG Parameter Type" registry requires Expert Review for allocations
in one of three possible ranges. The expert should be a person with a general
familiarity with LDP and this draft/RFC.

(19) Describe reviews and automated checks performed by the Document Shepherd
to validate sections of the document written in a formal language, such as XML
code, BNF rules, MIB definitions, etc.

N/A.
