Shepherd writeup

The MPLS Working Group requests that 

                   RFC6374 Synonymous Flow Labels

are published as an RFC on the Standards Track.

(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?

  The document should be published as a Proposed Standard, it specifies
  protocoal and proceedures.

(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 extends the OAM procedures defined in RFC 8372 (for
   p2p and p2mp LSPs only), to include how to do Loss Measurment and 
   Delay Measurement for the normal packet MPLS LSPs (mp2p). It also 
   introduces a number of more sophisticated measurements that are 
   applicable to p2p, p2mp and mp2p. The document addresses a
   number of problems that may lead to significant packet accounting
   problems, e.g. when the network uses ECMP.

Working Group Summary:

   The working group process has been smooth, it was unfortunately been
   delayed between the wglc and requesting publication, due to a
   misunderstanding where the authors and chairs were waiting and 
   authors were waiting for eachother, and the state of the working 
   group process were incorrectly captured in the in the data

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, YANG 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? 

   We currently do not know of impleentations, but we have sent out an
   implementtion poll and will update the shepherds write-up as soon as
   we get more information.

   On the other hand the discussion that took place during the 
   development of this docuement revealed that at least 3-4 companies 
   intend to implement.

   No MIB Doctor, YANG Doctor, Media Type or other expert review outside
   the working group is necesarry for this document.


   Deborah Brungard is the responsible AD
   Loa Andersson is the Document Shepherd

(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 discussion of Synonymous Flow Labels, the shepherd as been part 
   the discussion all the time since it was first brought to the 
   working group (actually I think that the document lead discussed 
   this we the shepherd prior to posting of the first draft).

   The document shepherd has read every document version and
   commented when becessary.

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

   No such 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 such review necessary.

(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 such concerns.

(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?

   During the life of a draft the MPLS wg does two IPR polls, one
   at the adoption on the document as a working group document and
   one at wglc. All authors and contributors has stated that they
   are unaware of any other IPRs than those disclosed to the IETF.

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

   There are three (3) IPR disclosures against this docuemnt,
   existing IPR disclosures are beought to the notice of the 
   working group at WGAP and WGLC. There have been no comments
   received. which traditionally is interpreted as that there
   are no concerns.

(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? 

   This is an extesion to MPLS that is widely understodd to 
   be a good approach to meet operatro requirements. Given the
   general acceptance of the SFL approach the document becomes
   obvious. However, it is still necessary, for inter-operability 
   reasons, to formally document exactly how SFLs are applied to 
   RFC 6374. Hence there is a strong backing from all over the 
   working group.

(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 such threats.

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

   The document passes the nits tool clean.

   The document shepherd has no discovered any further nitss.

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

     No such reviews necessary.

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

    Yes, the references ae correctly split in normative and informative.

(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 the normative references are to existing 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.

    All the normative referneces are to Standard Track RFCs

(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. 

   The publication of this document will not change the status the
   status of any other document.

(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 8126).

   The IANA section is fairly simple, 4 new code point from two existing 
   registries. The section has been reviewed continiously, in fact version
   -08 was triggered by shepherd comments on the IANA section.

(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. 

   Mo new IANA registries

(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, YANG modules, etc.

   No such automated reviews necessary

(20) If the document contains a YANG module, has the module been checked with any of the recommended validation tools ( for syntax and formatting validation? If there are any resulting errors or warnings, what is the justification for not fixing them at this time? Does the YANG module comply with the Network Management Datastore Architecture (NMDA) as specified in RFC8342?

   The document does not contaim a YANG module.
