The last Shepherd writeup of this draft was from Dec 2015 (v8 and v9 of the document). The text below is intended to update that writeup based on v12 of the document. Let me know if you have any questions. Thanks, Dave (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? Informational. This is indicated on the title page header, and is appropriate since this document specifies requirements for future work. (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 The MPLS transport profile (MPLS-TP) includes OAM functions which enable maintenance tools that may be used by network operators and service providers for fault location, survivability, performance monitoring, in-service and out- of-service measurements. Based on identified problems, this document provides considerations for the specification of new requirements to consider a new improved mechanism for hitless transport path segment monitoring to be named Enhanced Path Segment Monitoring (EPSM). Working Group Summary WG progress was relatively smooth with no controversy. Document Quality The document has been well reviewed by the WG and also as mentioned below, and updated accordingly. As a requirements document it does not specify any protocol to be implemented, but rather specifies requirements which will be used to guide future work. Personnel David Sinicrope is the current Document Shepherd, taking over from Ross Callon. 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. The document shepherd has reviewed the document, and the document has been updated in response to his comments. At WG chair request Huub van Helvoort has also done a grammatical review of the document. In addition Rtg Dir Review was performed and liaisons to ITU-T SG15 generated to inform them of the draft and its intent to describe different MPLS-TP OAM requirements those communicated from ITU-T previously. (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? no concerns. (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 additional review needed. (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. While no explicit concerns, it should be noted that the document entertains “analysis of existing MPLS-TP OAM mechanisms” and “provides requirements to guide development of new OAM tools” on a topic where requirements were established, led and communicated from ITU-T SG15. There has been liaison activity related to this topic and I-D dating back to 2010 with https://datatracker.ietf.org/liaison/917/. Continued open communication with ITU-T SG15 should be maintained to ensure continuity and migration from existing requirements and solutions. (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. (this is being reconfirmed for the latest revision) (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. No IPR disclosures have been filed that reference this document. (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? Rough consensus. The document has been progressing slowly for quite a while and there was positive response to the WGLC with no objections albeit from a small handful of people, mostly from the author’s affiliations. (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 discontent or objection, just caution as noted by the comments regarding ITU-T above. (11) Identify any ID nits the Document Shepherd has found in this document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough. IDnits pointed to a few minor issues which should be corrected in v12. (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. It should be noted that there are M#/Mandatory requirements made to informative references. (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? All references are to published RFCs. (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 downrefs. Earlier versions of the document did have downrefs but it was clear that these should have been informative references, and the document was updated accordingly. (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. not applicable. (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). There are no requests for IANA actions in this document. This is appropriate. (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. There are no requests for IANA actions in this document. (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.
