(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?
This document is requested to be published as a Proposed
Standards. This is the proper type of RFC as it requires IANA
registrations for a registry that requires a standards track RFC.
This RFC type is indicated on the title page.
(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 specifies the syntax of Uniform Resource Identifier
(URI) schemes for the Traversal Using Relays around NAT (TURN)
protocol. It defines two URI schemes that can be used to provision
the configuration values needed by the resolution mechanism defined in
RFC5928.
Working Group Summary:
Was the document considered in any WG, and if so, why was
it not adopted as a work item there? Was there controversy
about particular points that caused the WG to not adopt the
document?
This all began six years ago attempting to standardize the TURN URI
scheme in the BEHAVE WG. The information in this document was
originally a part of a BEHAVE WG item (now RFC 5928) and went through
WGLC (in 2009). For reference, see:
https://www.ietf.org/mail-archive/web/uri-review/current/msg01089.html
At that time there were no applications of this on the Internet, so it
was deemed premature and the TURN URI standardization component was
split off into its own document and remained a draft. Recently, the
need for a standard URI scheme for TURN and STUN has arisen in the
context of RTCWeb. Cullen Jennings pointed this out and consequently
this resurrected the dormant TURN URI draft and produced a new
companion document standardizing the STUN URI scheme
(draft-nandakumar-rtcweb-stun-uri-04.txt). Note that the STUN URI
draft came about more recently but is intended to be complementary.
These drafts are now normatively referenced by the W3C
(http://www.w3.org/TR/webrtc/ and
http://dev.w3.org/2011/webrtc/editor/webrtc.html) and have already
been implemented in Google (Chrome) and Mozilla (Firefox) in their
current STUN/TURN server configuration code.
The narrow scope of the document didn't warrant a WG milestone in
RTCWEB, so RAI and APPs ADs (Gonzalo Camarillo and Pete Resnick)
agreed Individual/AD sponsoring was the proper course of action for
the document and agreed to progress it.
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, 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?

Both Google and Mozilla have already implemented this draft and it is
expected that other web browsers will also implement this draft.
This draft has benefited from considerable review over the course of
its long history. The document was reviewed back in 2009 and went
through WGLC before being split in what became RFC 5928 and the
predecessor of the current TURN URI draft:
http://www.ietf.org/mail-archive/web/behave/current/msg07061.htmlhttp://www.ietf.org/mail-archive/web/behave/current/msg07354.html
The current document was also sent for review in the IETF RTCWEB and
W3C WebRTC mailing-lists:
http://www.ietf.org/mail-archive/web/rtcweb/current/msg03476.html
and also the BEHAVE WG mailing list:
http://www.ietf.org/mail-archive/web/behave/current/msg10047.htmlhttp://www.ietf.org/mail-archive/web/behave/current/msg10279.html
It has also benefited from expert review on the uri-review
mailing-list back in 2009:
https://www.ietf.org/mail-archive/web/uri-review/current/msg01063.html
and again recently for the current incarnation of the document:
http://www.ietf.org/mail-archive/web/uri-review/current/msg01651.html
