Shepherd writeup

This is the Publication Request and document shepherd write-up for

Considerations for Benchmarking Virtual Network Functions and Their

This version is dated 9 January 2017.

Sarah Banks is the Document Shepherd, and prepared this form: January 2017.

(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, as indicated on the title page. All BMWG RFCs are traditionally
Informational, in part because they do not define protocols and the traditional
conditions for standards track advancement did not apply.  However, they are
specifications and the RFC 2119 terms are applicable to identify the level of

(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 draft examines considerations for benchmarking virtualized network
functions (VNFs) and their supported infrastructure, with consideration for
general-purpose hardware, and considers benchmarking both physical and virtual
network functions in the same fashion, allowing for comparison between the two,
where possible.

Working Group Summary:
There has been a fair amount of work done on this draft, and progress made on
revisions, feedback, and comments. Several presentations have been made in the
room during IETF meetings, and followup and discussion taken to the BMWG list.
This draft is particularly useful, given the popularity of VNF's within the

Document Quality:
This document is ready for publication.


Who is the Document Shepherd? Who is the Responsible Area Director?
Sarah Banks is Shepherd, Joel Jaeggli is AD.

(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.

I've reviewed this draft at WGLC. Nits check is clean, with 2 warnings that
have no impact on publication. All comments and feedback by the WG have been
addressed by the Author.

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


(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 specific reason to call out these reviews here, but the document itself was
reviewed in ETSI NFV, and used as a reference by at least one of the TST WG and
IFA WF specifications (2 references in total). The document has also been
reviewed by several individuals from the OPNFV community, and NFVRG (IRTF) is
aware of the draft.

(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.


(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?

No IPR has been filed.

(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 disclosed.

(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?

A WGLC was called on March 23, 2016, and closed June 20, 2016. There was
significant support for this work at IETF 95, and consensus was achieved
amongst 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.)


(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.

No nits

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


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

All references are either Normative or Informative, and marked as such.

(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?


(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


(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.


(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 IANA actions required.

(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.


(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.
