Document Writeup for Working Group Documents

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. This is appropriate because the draft specifies protocol 
    extensions. The title page identifies the draft as Standards Track.

(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:

Relevant content can frequently be found in the abstract and/or introduction of the document. If not, this may be an indication that there are deficiencies in the abstract or introduction.

   The Hierarchical Path Computation Element (H-PCE) architecture is
   defined in RFC 6805.  It provides a mechanism to derive an optimum
   end-to-end path in a multi-domain environment by using a hierarchical
   relationship between domains to select the optimum sequence of
   domains and optimum paths across those domains. This document defines 
   extensions to the Path Computation Element Protocol (PCEP) to support
   Hierarchical PCE procedures.


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?

    No controversies. The document was initially marked experimental and after
    discussion within the WG it was moved to proposed standards. The consensus 
    behind the document is good and it is bases for further H-PCE related work
    such as stateful H-PCE and ACTN. 

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 are several PCEP implementations supporting H-PCE. This 
    includes commercial as well as open source implementations. 
    This information can be found in the appendix.

    Substantial review was done by Adrian Farrel and Dhruv Dhody. 

Personnel:

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

    Dhruv Dhody is the document shepherd.
    Deborah Brungard is the responsible area director.

(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.

    In my opinion, the document is ready. The shepherd review provided 
    comments and suggestion to the authors which were handled during the latest 
    update. 

(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.

    The usual Routing Directorate's review is expected.

(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.

    No

(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. An IPR check was done in Sep 2018.

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

    Yes. One "late" IPR disclosure.  The inventors and the document authors are different and the disclosure ("no-assert") was made when this was discovered.

(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?

    The document triggered various discussions and it has been carefully 
    reviewed by a few interested individuals. Overall it can be considered as a 
    consensus of the WG as a whole.

(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.

    None. 

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

    Not Applicable

(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.

(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 section is clear. It mixes new request and import from 
    another RFCs in an precise manner.

(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.

    Not Applicable.

(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.)

    Not Applicable.
