Because it updates/obsoletes an existing "Proposed Standard" protocol
definition.

Yes.

Technical Summary

  This document updates the definition of Traversal Using Relays around NAT
  (TURN), RFC5766, a protocol that allows the host to control the operation of
  the relay and to exchange packets with its peers using the relay. The
  updates improve protocol support for IPv6 and DTLS, adds support for
  receiving ICMP packets, and updates PMTUD. The new revision also improves
  document clarity regarding tunnel amplification attacks and packet
  translation.

Working Group Summary

  This document represents one of the core milestones for the TRAM working
  group and as such has undergone significant discussion, review, and
  revision.  There has been no significant controversy of note in the updates
  to this document. This document's dependence upon some other documents, most
  notably updates to Session Traversal Utilites for NAT (STUN)
  I-D.ietf-tram-stunbis, have led to delay in this document's completion, but
  have not increased the difficulty of coming to consensus on this document's
  contents.

Document Quality

  This draft has continuously been reviewed by many different people
  throughout its history. The most significant updates have been the subject
  of discussion in TRAM WG meetings throughout the documents lifetime.

  Comprehensive reviews of the full set of updates have been done by two
  active WG members. This review includes coverage for consistency with the
  related stunbis document. All of the review feeback has been addressed by
  the authors.

Personnel

  Document Shepherd: Brandon Williams
  Responsible Area Director: Spencer Dawkins

> (3) Briefly describe the review of this document that was performed by

Full review + nit checker.

> (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.

No additional focused review was considered necessary for this document.

> (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

> concerns here.

No 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.

Yes.

> (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 disclosure has been filed.

> (9) How solid is the WG consensus behind this document? Does it

> being silent, or does the WG as a whole understand and agree with it?   

Consensus represents 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

> separate email because this questionnaire is publicly available.) 

No such threats have been made.

> (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.

All relevant nits have been resolved.

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

No such reviews were done or deemed to be required.

> (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 to RFCs, except for I-D.ietf-tram-stunbis, which
has already been advanced to the IESG and is under active review.

> (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. 

There are no downward normative references.

> (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 title page, abstract, and introduction all indicate that RFCs 5766 and
6156 are obsoleted by this one.

> (17) Describe the Document Shepherd's review of the IANA considerations
> section, especially with regard to its consistency with the body of the
> document.

Careful review.

> Confirm that all protocol extensions that the document makes
> are associated with the appropriate reservations in IANA registries.

I confirm.

> Confirm that any referenced IANA registries have been clearly
> identified.

I confirm.

> 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 newly created IANA registries.

> (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.

No new IANA registries are requested.

> (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.

None.
