09 | Bruno Decraene | (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? … (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? Intended status is Standards Track. This is indicated in the front page of the draft and in the datatracker. This seems a proper type of RFC for a document defining (in §5.1) a data plane behavior on the Service Function Forwarders (SFF) which needs to be coordinated with the Segment Routing (SR) source node. (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 describes the integration of Network Service Header (NSH) and Segment Routing (SR), as well as the encapsulation format, to support Service Function Chaining (SFC) while maintaining separation of the service and transport planes. Working Group Summary: WG Last Call has been copied to the SFC WG. There was relatively limited support but no controversy. The document has passed Routing and Internet directorate review. Document Quality: There are no implementation nor implementation plan which have been publicly shared. Personnel: The Document Shepherd is Bruno Decraene The Responsible Area Director is Martin Vigoureux (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. Id nits checks. Multiple complete readings of this document and discussions with authors on the mailing list. Review of SPRING WG mailing list on the WG and individual draft https://mailarchive.ietf.org/arch/browse/spring/?q=draft-ietf-spring-nsh-sr (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? More reviews would have been better but I've checked with the SFC WG chairs and this level of review is inline with other SFC documents. I don't have 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. An early directorate review has been requested to the Routing and Internet directorate. (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 specific concern. This solution may be useful in some scenario (both SR & NSH used). However, so far there is no implementation. (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? Each author has confirmed IPR disclosure on the WG mailing list. Each contributor except Syed Hassan (Cisco System, inc. shassan@cisco.com) has confirmed IPR disclosure on the WG mailing list. Even though his email seems to work, Syed never replied. https://mailarchive.ietf.org/arch/browse/spring/?q=%22IPR%20call%20for%20draft-ietf-spring-nsh-sr%22 (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. Two IPR disclosure have been filed. https://datatracker.ietf.org/ipr/search/?submit=draft&id=draft-ietf-spring-nsh-sr There was no WG discussion on the IPR. (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? WGLC was performed in the SPRING WG and copied to the SFC WG. A fraction of the WG supports progressing this document. No objection from the rest of the WG. (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 one has threatened an appeal or otherwise indicated extreme discontent. (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. Id nits complains about a non-RFC6890-compliant IPv4 addresses but it's actually a section number (4.3.1.1) (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 formal review. (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? All normative references are 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. Yes, there are two downward normative references: [RFC7665] "Service Function Chaining (SFC) Architecture". This document had already been listed as downward normative references for RFC 8300 Network Service Header (NSH) [RFC8596] "MPLS Transport Encapsulation for the Service Function Chaining (SFC) Network Service Header (NSH)" (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. Publication of this document would not change the status of any existing RFC. (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). Both IANA sections checked. Plus RFC 8126 section 3.1 reread. (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. This document does not define new IANA registry. (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. This document does not use formal language. (20) If the document contains a YANG module, has the module been checked with any of the recommended validation tools (https://trac.ietf.org/trac/ops/wiki/yang-review-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? This document does not contain YANG module |
