Subject: [sipcore] Protocol Action: 'IANA Registry for the Session 
Initiation Protocol	(SIP) "Priority" Header Field' to Proposed Standard 
(draft-ietf-sipcore-priority-00.txt)

<rfc-editor@rfc-editor.org>

The IESG has approved the following document:
- 'IANA Registry for the Session Initiation Protocol (SIP) "Priority"
    Header Field'
   (draft-ietf-sipcore-priority-00.txt) as Proposed Standard

This document is the product of the Session Initiation Protocol Core
Working Group.

The IESG contact persons are Robert Sparks and Gonzalo Camarillo.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-ietf-sipcore-priority/




Technical Summary

     This document defines a new IANA registry to keep track of the values
     defined for the Session Initiation Protocol (SIP) "Priority" header
     field.  This header field was defined in [RFC3261], section 20.26.
     It was clearly specified in a way that allows for the creation of new
     values beyond those originally specified; however, no registry has
     been established for it.

Working Group Summary

     This work was initiated because the ECRIT WG had a need to define
     a new value for the Priority header field, for use in new document
     draft-ietf-ecrit-psap-callback. RFC 3261 was written to allow such
     extensions, but had no mechanism to manage extensions.
     The chairs of ECRIT and SIPCORE and the ADs discussed this and
     considered various mechanisms to move forward. The alternatives
     considered were:

     - construct the ECRIT document as an update to RFC 3261,
       extending the syntax of the Priority header field.

     - construct the ECRIT document as an update to RFC 3261,
       introducing an IANA registry for Priority header field values,
       populating it with those values defined in RFC 3261 and also
       the desired new value.

     - publish a new draft, in the SIPCORE WG, that updates RFC 3261,
       introducing an IANA registry for Priority header field values,
       and populating it with those values defined in RFC 3261.
       Then the ECRIT WG can modify their document to register the new
       value in accord with the new registration procedures.

     We concluded that the last approach was the cleanest one.
     This draft is result.

Document Quality

   Are there existing implementations of the protocol?

       This defines no new protocol.

       draft-ietf-ecrit-psap-callback is progressing in parallel and
       will make use of the new registration mechanism.

   Have a significant number of vendors indicated their plan to
   implement the specification?

       N/A

   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?

       The document is very simple, so didn't require great effort
       to review. The primary commenters on the draft were
       Christer Holmberg and Keith Drage.

   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?

       N/A

RFC-Editor Note:

Please make the following three changes to version -00 of this draft)

Change 1 (replaces text):

OLD:
This document adds a new registry, "Priority Header Field Values."

NEW:
This document adds a new sub-registry, "Priority Header Field Values" to the
"Session Initiation Protocol (SIP) Parameters" registry page.

Change 2 (only adds text):

OLD:
The policy for registration of values in this registry is "IETF Review," 
as that term is defined by [RFC5226].

NEW:
The policy for registration of values in this registry is "IETF Review," 
as that term is defined by [RFC5226]. This policy was chosen over 
lighter-weight policies due the potential architectural impact of the 
semantics associated with new values. Efforts considering adding a 
Priority value should consider whether the SIP Resource-Priority 
[RFC4412] or even a different protocol would be more appropriate for 
achieving their requirements.

Change 3 :

Please add an informational reference to RFC4412.

The IESG has approved the following document:
- 'An Extension to the Session Description Protocol (SDP) and Real-time
  Transport Protocol (RTP) for Media Loopback'
 (draft-ietf-mmusic-media-loopback-27.txt) as Proposed Standard

This document is the product of the Multiparty Multimedia Session Control
Working Group.

The IESG contact persons are Gonzalo Camarillo and Robert Sparks.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-ietf-mmusic-media-loopback/




Technical Summary

This document provides extensions to the Session Description Protocol
(SDP) and the Real-time Transport Protocol (RTP) for enabling looping
of sent media. Media loopback is especially popular in ensuring the
quality of transport to the edge of a given VoIP, Real-time Text or
Video over IP service. The extension defined herein adds new SDP media
types and attributes, which enable establishment of media sessions
where the media is looped back to the transmitter. Such media sessions
will serve as monitoring and troubleshooting tools by providing the
means for measurement of more advanced VoIP, Real-time Text and Video
over IP performance metrics.

Working Group Summary

The first version of the document was available at the end of 2004.
Since that time, the working group has been discussing a number of
issues toward getting the consensus that is believed to be achieved in
version 22.

The description of a latching mechanism to traverse NATs and firewalls
was discussed and decided to be removed from the actual document in
favor of standard NAT traversal techniques such as ICE/STUN/TURN.

Document Quality

At least four implementations of this functionality are known. Four
other vendors have indicated they plan to implement it.

The document was WGLCed on version 16. Additionally, the PAYLOAD WG
also conducted a thorough review of the same 16 version. As a result of
these reviews, 34 changes were requested by, among others, Tolga
Asveren, Dan Wing, Emil Ivov, Flemming Andreasen, and Miguel A. Garcia.
These comments were subsequently introduced into versions 17 and 18. A
new WGLC was issued on version 18, bringing a new set of comments by
Flemming Andreasen, Magnus Westerlund, and Gunnar Hellstrom. These were
addressed in version 19.

At least Magnus Westerlund and Flemming Andreasen did a thorough review
of the document as part of the WGLC on version 18.

Version 18 was sent to the ietf-types mailing list for review on April
4, 2012. Bjorern Hoehrmann and Magnus Westerlund posted comments that
were addressed in version 19.

We ran a WGLC on data-only, and got some comments.  The discussion raises s=
ome fundamental issues that authors have been discussing.  Here is our curr=
ent thinking, which we would like discussion on before we rev the draft.

"Data Only" was intended, originally, for a sensor equipped automaton to se=
nd an alarm to a PSAP when there was no media.  It uses a CAP message in th=
e body of a MESSAGE to do that.

It's been observed that there are cases where you have exactly the same kin=
d of thing, with the same data, but you ALSO have media.  In such a case, w=
e would like to have the data sent the same way (CAP message in a body)

It's also been asked how updates to the alarm are sent.  At one point there=
 was some discussion of using MSRP to send a series of messages.  Authors d=
on't like this mechanism because it doesn't allow the PSAP to control the r=
ate of updates.  We suggest that updates be handled with a SUB/NOT, with fi=
ltering, and the CAP message in the body of the NOTIFY.

If we were to do this, it would be major surgery to the existing draft, inc=
luding a name change.  Nevertheless, that seems to be the right way to go. =
 We would:
a)Define the mechanism to carry a CAP message in the body of a SIP transact=
ion, and define it for use in INVITE, MESSAGE and NOTIFY
b) Specify that INVITE is appropriate for alarms with media (creates sessio=
n), and MESSAGE for alarms without media (doesn't create a session), but ot=
herwise are equivalent.
c) Define a SUB/NOT package, with filtering, for updates to the alarm data
d) Change the name to something like "Citizen to Authority Alerts".

This would mean re-running WGLC.

I am somewhat reluctant to do major surgery on the existing draft.  Instead,
my advice would be to define the SUB/NOT package in a separate document.
That would allow this document to be completed expeditiously.

I've no major problem with most of this, but I thought one fairly common us=
e case was that you sent a body of data, and after that there was a decisio=
n that media might be appropriate.=20

So data device is in car, which is in accident - data device automatically =
fires off emergency accident data, but then there is a decision from either=
 end that this needs to carry voice media to turn this into an emergency ca=
ll with the driver.

So how would you handle this case with the proposal given. One option would=
 be to assume from the start that the voice would be needed in this use cas=
e (even if it was not used), but are there alternatives.

Regards

Keith
