>(1.a)  Who is the Document Shepherd for this document?  Has the

Lou Berger is the Document Shepherd.

He has reviewed the document and believe this version is ready for
publication at the intended status.

>(1.b)  Has the document had adequate review both from key WG members
>      and from key non-WG members?  Does the Document Shepherd have

>      have been performed?

The document has received adequate review and discussion.  It has been
revised to be consistent with WG opinion and other related activities in
the IETF.

>(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?

No.

>(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?

No.

> For example, perhaps he
>      or she is uncomfortable with certain parts of the document, or

>      event, if the WG has discussed those issues and has indicated

>      this issue.

No IPR disclosures were found.

>(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?

Consensus appears to be good.

>(1.f)  Has anyone threatened an appeal or otherwise indicated extreme
>      discontent?  If so, please summarize 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 threats. No discontent.

>(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

>      Doctor, media type, and URI type reviews?  If the document
>      does not already indicate its intended status at the top of
>      the first page, please indicate the intended status here.

Yes.

>(1.h)  Has the document split its references into normative and
>      informative?

Yes.

> Are there normative references to documents that
>      are not ready for advancement or are otherwise in an unclear
>      state?

No.  There are two references that are drafts:

  [GMPLS-RR] Berger, L., Papadimitriou, D., and JP. Vasseur,
              "PathErr Message Triggered MPLS and GMPLS LSP Reroute",
              draft-ietf-mpls-gmpls-lsp-reroute, Work in progress.

  [HIER-BIS] Shiomoto, K., and Farrel, A., "Procedures for Dynamically
            Signaled Hierarchical Label Switched Paths", draft-ietf
            ccamp-lsp-hierarchy-bis, Work in progress.

The first draft is in the RFC editor's queue and the second is in the
IESG publication process.

> If such normative references exist, what is the
>      strategy for their completion?

Both documents are essential complete and are in the publication
process.

> 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].

No downward references.

>(1.i)  Has the Document Shepherd verified that the document's IANA
>      Considerations 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

The IANA section looks good.

>(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, no automated checks needed.

>(1.k)  The IESG approval announcement includes a Document

>      "Action" announcements for approved documents.  The approval
>      announcement contains the following sections:
>
>      Technical Summary
>          Relevant content can frequently be found in the abstract

    This document extends GMPLS routing and signaling to support the
    operation of GMPLS Multi-Layer/Multi-Region Networks. A network
    comprised of multiple switching types (e.g. PSC and TDM) controlled
    by a single GMPLS control plane instance is called a Multi-Region
    Network (MRN).  A network comprising transport nodes participating in
    different data plane switching layers controlled by a single GMPLS
    control plane instance is called a Multi-Layer Network (MLN). This
    document defines GMPLS RSVP, OSPF and IS-IS to cover GMPLS MLN/MRN
    requirements.


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

This document received much attention and discussion in its early
revisions.  The document has been largely stable for quite some time,
mainly needing revisions as part of the publication 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 have been no public statements related to intent to implement, but
the portions of the extensions are now being used as part of the GMPLS
tool set and are (at least) expected to implemented in those contexts.
