This document captures experiences in implementing systems based on
the ENUM protocol and experiences of ENUM data that have been created
by others.  As such, it clarifies the ENUM and Dynamic Delegation
Discovery System standards.  Its aim is to help others by reporting
both what is "out there" and potential pitfalls in interpreting the
set of documents that specify the ENUM protocol.  It does not revise
the standards but is intended to provide technical input to future
revisions of those documents.  This memo provides information for 
the Internet community.

This document is a product of the Telephone Number Mapping Working Group of the IETF.

All,

We have submitted a new draft describing another method for incorporating
trunk group information in an ENUM response.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.

    Title           : Trunk Group Use in ENUM
    Author(s)       : D. Malas, T. Creighton
    Filename        : draft-malas-enum-trunk-sip-00.txt
    Pages           : 7
    Date            : 2009-03-04

This document concludes that incorporating trunk group parameters
into an Electronic Number (ENUM) response for the Session Initiation
Protocol (SIP) [RFC3261] service URI is a more effective approach
compared to defining a new ENUM service type for a 'trunk'.  Upon
further review of the existing ENUM trunk group draft
[I-D.ietf-enum-trunkgroup] and practical operator experience, this
draft recommends the use of the current trunk group contexts as
defined in [RFC4904] as additional parameters in the E2U+SIP
enumservice NAPTR record [RFC3403] URI.

A URL for this Internet-Draft is:

Daryl

To the list ..

 

FYI this draft essentially supersedes the previous draft that Tom Creighton
and I co authored earlier.

 

As far as I'm personally concerned this is still a legitimate WG item as it
describes, in another way , work we had already approved. It does have
significant applicability in the market today.

 

I have no issues with this proceeding as a ENUM WG document unless there are
objections.  We are close to closure but fast tracking this to WGLC could be
of help to operators looking at this type of function.

 

Comments? Any objections to a fast track?

Subject: [Enum] New Draft: Trunk Group Use in ENUM

 

All,

We have submitted a new draft describing another method for incorporating
trunk group information in an ENUM response.

A New Internet-Draft is available from the on-line Internet-Drafts
directories.

    Title           : Trunk Group Use in ENUM
    Author(s)       : D. Malas, T. Creighton
    Filename        : draft-malas-enum-trunk-sip-00.txt
    Pages           : 7
    Date            : 2009-03-04

This document concludes that incorporating trunk group parameters
into an Electronic Number (ENUM) response for the Session Initiation
Protocol (SIP) [RFC3261] service URI is a more effective approach
compared to defining a new ENUM service type for a 'trunk'.  Upon
further review of the existing ENUM trunk group draft
[I-D.ietf-enum-trunkgroup] and practical operator experience, this
draft recommends the use of the current trunk group contexts as
defined in [RFC4904] as additional parameters in the E2U+SIP

Hi Rich

Why don't we use the new process as decribed in

   http://tools.ietf.org/html/draft-ietf-enum-enumservices-guide

for Trunk Group? So, the document does not need to be WG item.
I believe it is not worth doing anything according to the old process at
this point in time.

cheers,
  Bernie

Hi Bernie, folks,
  Agreed.
If there is a crucial reason to force this through the IETF on the old =20=

track, then let's discuss this at the ENUM WG meeting :).
all the best,
   Lawrence

I believe the point of the draft is that it defines the usage of Trunk Grou=
ps within SIP URIs without a unique service type.  Therefore no additional =
ENUM service is defined and the draft falls outside of the service registra=
tion process.  By comparing this method to a non-registered service type of=
 e2u+trunk, it creates some confusion.  So, registration of the service typ=
e or removal of the reference might also be appropriate.

I think the draft is should be fast tracked as there is a need to document =
the use of trunk groups within ENUM.

One other more specific comment is that the document should define the trea=
tment of the Trunk Group parameters within the ENUM client.  The options ar=
e:

a. Override the URI host and route based on embedded trunk group.
b. Route based on the URI host and forward the trunk group parameters downs=
tream for further processing.
c. Define either behavior as acceptable or a matter of local policy.

As Don said the purpose of this draft is to describe a method for trunkgroup
that does not require a new Enumservice type.... a BGP essentially. Which is
why I have no objection to a fast track.

However should someone want to have a E2U+SIP:TRUNK then yes the new
registration method could create that...if and when we can get the document
approved by the IESG this century.

My (quick) 2c:

- I'm not a big fan of accepting new work items in the ENUM working group.

- This document does neither register nor modify nor delete a registered 
numservice. It's a mixture between arguments why we should stop working 
on something in progress plus operational recommendations on the *use* 
of some technology in the context of some SIP scenarios.

- As others mentioned, the Enumservice registration process is not 
appropriate for this document. However, the document recommends to drop 
some work that the ENUM WG has in progress.

(BTW, i can't find a single reference to the "trunk:" URI scheme that 
the draft mentions... Is that a new proposal, or a typo in the draft? 
The ENUM trunk group draft does not specify that URI scheme..)

- When i look at the SPEERMINT charter, the following paragraph fits the 
document quite well (Notice the word *trunking*):

"More specifically, SPEERMINT focuses on real-time session
routing architectures and their associated use cases.
Deliverables here include the specification of the various
types of application flows, such as signaling and media flows, in
such networks, and includes both trunking and peer-to-peer
flows."

Another thing that perfectly fits what is described in the documents is 
the SPEERMINT NAPTR use draft.

Granted, the use cases described might happen more within a SSPs network 
rather than between networks (unless SSPs are happy to expose their 
trunk group identifiers, which i doubt...)

(On the other hand, the item "3. The working group will continue examine 
and document various aspects of ENUM administrative and /or operational 
procedures irrespective of
whether e164.arpa domain is used." from the ENUM charter would probably 
work as well..)

- Therefore, i think that SPEERMINT / ENUM WGs should do the following:

a) Instead of "fast tracking" that document, the ENUM WG should rather 
agree whether or not they want to stop work on (and drop / expire) the 
existing trunk group draft (which was not too uncontroversial anyway). I 
don't think we need to accept that document as WG item to be able to 
decide that we stop work on the other item... if we accept that item as 
WG document, then we'd need to invest some effort into 
reviewing/clarifying etc work..

b) otoh, SPEERMINT is still active, and probably should discuss whether 
they want to either accept that draft as an additional WG item, or merge 
it's contents into the NAPTR Use draft..

comments?

A. this is not new work ..the original draft was an approved WG item. Its
simply expired.

Shockey, R. and T. Creighton, "IANA Registration for an
              Enumservice Trunkgroup", draft-ietf-enum-trunkgroup-00
              (work in progress), July 2008.

Yes it's should be structured as a BCP. The idea is to actually document
something that actually works vs waiting another year or whatever to try and
create a new enum service. I personally had no objection to completely
rewriting the existing 00 draft but the authors chose to submit a new draft.

So you want to send this to SPEERMINT where again it will get lost in the
shuffle?

Daryl, Jason ??  Do you want to do this?


Cant we in the IETF actually DO something?  This was the last piece of ENUM
work that got left by the wayside.

I know we should be shutting down the ENUM WG but this is IMHO pretty
simple, it's a real application that has immediate use in operators network.
Its not complicated and IMHO a successor draft should eliminate the
discussion of :trunk and focus specifically on the BCP of [RFC4904] within
the existing context of the E2U+SIP enumservice NAPTR record [RFC3403] URI. 

The point of this draft IMHO is that you don't need a new Enumservice to
accomplish the requirement. That is a good thing. Why should internal SSP
network elements parse through a specific "trunk" NAPTR record when it can
simply look for E2U+SIP and execute accordingly.

IMHO the authors should have been more explicit in describing the use case
that exposure of this data is typically only within a SSP network. NO TCAP.

Again rewrite this into the existing trunkgroup expired draft? Fine .. send
it to SPEERMINT? No thank you.

More stall and delay. I just don't see the point. Why do you want to get
this draft bogged down in some IETF procedural issue?  Cant we just fix it
and shut the WG down? This draft, again, has real and demonstrable
applicability to internal SSP operator networks RIGHT NOW, unlike some RAI
drafts I see floating around.

In any event this would require some review by the AD's so given the
transition we'll have to check with them.

Don,

Your assumption is correct.  We are not proposing a new service type.  This
draft suggests something quite to the contrary.  It proposes a method of
including trunk information without a new service type.  Based on this, I do
not think it falls within the scope of this process:
http://tools.ietf.org/html/draft-ietf-enum-enumservices-guide

Regarding the treatment of the trunk group parameters within the ENUM
client, I think this would be a good addition to the draft and would like to
work with you further on some language when the working group decides how to
move forward.

Regards,

Daryl

Daryl is a co-author, so I can comment.  I'm willing to consider it but only
if the ENUM WG chairs feel strongly that this should come over to us.  If
you guys can process it rapidly, and feel it is within your scope, then go
for it.  If you are not sure it is totally in-scope and you expect to shut
down soon so that you cannot move the document ahead, then we could fit this
in as an "implementer-specific" document.  That's a long way of saying we
can help if you like, but it's really up to you and Patrik.  :-)

If you can address it rapidly here in ENUM, you should, IMHO.

Well thanks for your prompt response. 

I just did not want to see what is a pretty simple BCP that solves a real
internal SSP problem that defines no new protocol specification, distract
from ongoing progress in SPEERMINT.

I understood that very well. However, the new draft is not the same work 
- it's some operational experience why we don't need the original work. 
   Fine as well, but not the same work.

I preferred to see it as a new draft anyway, because the subject of the 
draft changed quite a lot (from an Enumservice registration to an 
operational practice).

What i meant is that i don't think we'd need to accept it as a WG item 
*just* to reason dropping the "trunk" registration work.

Now if i hear people saying it contains important operational 
experience, *then* it's a different story.

Whether it should be done in SPEERMINT or ENUM is a different question.

Well, if it's about finding the path of least resistance, then the 
sedated ENUM WG might work well :)

ok, ok, i'm convinced - i was just a bit reluctant to replace work that 
was expired anyway with new work. If it's the easiest way, the lets 
proceed it.

Hi Folks,
  beware - *who* gets to decide if a WG draft is dead?
 From experience, some get vocally unhappy if the authors just state
(the bl**din' obvious) that the draft is pining for the fjords.
Thus shouldn't "the management" (Alex, Richard, Patrik) formally
raise the proposal that the existing expired draft is dead, if it
is?

Also, why is putting this new stuff in the clutches of a sleeping
WG (or an inchoate one) going to make it any faster getting any BCP
through the IETF/IESG process? Does anyone remember IPTEL?

all the best,
   Lawrence

Technical Summary

This memo defines an interim solution for Infrastructure ENUM to allow a
combined User (i.e. RFC3761-based) ENUM and Infrastructure
(draft-ietf-enum-infrastructure-based) ENUM implementation to exist in
e164.arpa as a national choice. The solution is intended as a transition
mechanism that would be phased out once a long-term Infrastucture ENUM
solution has been put into place.

Working Group Summary

The ENUM WG supported the advancement of this memo as an Informational
RFC in order to document a potential solution.

Technical Summary

This document motivates the existence of a parallel namespace for
"Infrastructure ENUM" outside of the so-called "User" namespace defined in
RFC3761. In particular, this parallel namespace might be used by carriers
who want to provision DNS records for telephone numbers independently of
the records provisioned by end users (number assignees).

Given the lack of announcement here, plus the lack of any mention of
enum on https://datatracker.ietf.org/meeting/74/agenda.html, can I conclude
that there will be no formal enum session at next week's IETF meeting?

Hi,

I have no expertise on the subject matter, but would like to share some
observations on process:

On Fri, Mar 06, 2009 at 02:22:03PM +0000, Lawrence Conroy wrote:

usually that's a WG consensus, either explicitly or by lack of motion as to
be determined by the chairs.  In this case however, it seems that the WG
(or those in the WG who actively follow the matter) have changed their mind
about the direction of the draft.  Posting a new I-D was one way, but if the
WG consensus is that the solution proposed in
"IANA Registration for an Enumservice Trunkgroup" is no longer the right one
and instead a parameter to the SIP URI, as proposed in Trunk Group Use in ENUM
will do better, then WG consensus could just direct the editors to re-write
accordingly.  Now, it seems that the editors change on the fly, too, but that's
up to the chairs (well, and any new editors) anyway.

I am a bit nervous about "fast tracking" in the last minute and the status
of BCP.  The former seldomly works out, but the current work item needs
to get off the WG's plate anyway.  The latter doesn't seem necessary,
especially since we're about to re-classify all (or many of) those Proposed
Standards anyway.  A purely Informational document would do, and is
definitely more lightweight.  The draft would be an Informational addendum
to RFC 3764, which it needs to reference normatively.

The draft itself, however, isn't really clear about the intended status
"IANA Registration for an Enumservice Trunkgroup".  This document is a normative
reference although it seems to have outlived its usefulness and actually the
registration in there is kind of revoked.
However, the "trunk" ENUM service doesn't yet appear in
<http://www.iana.org/assignments/enum-services> if my pattern matching skills
suffice.  So, instead of pursuing the old draft and immediately revoking the
registration (or declaring it a no go), the new (well, "revised") draft
should just state the new intended method of using trunk groups in ENUM
and incorporate verbatim the relevant parts of the earlier draft (without
suggesting there actually _is_ a valid ENUM servcie registration) in an
appendix.
It wouldn't be the first time an IETF WG started an effort to do FOO and the
document ends with the title "Why not to FOO".

I'm not sure I follow the rationale in the first paragraph of section 1.2,
it feels like it's superseded by the newly born 5483 -- congratulations, by
the way.

-Peter

Well as one of the original document editors here I had no issue with the
change of direction from a new Enumservice registration to a simpler BCP
describing the use of 4904 in an existing E2U+SIP context. My larger issue
here was that I did not want the usually dysfunctional IETF process issues
to get in the way of a perfectly sensible technical solution to a very real
problem and take the issue off the table and close the WG.

My basic point.

 The latter doesn't seem necessary,

Why informational vs BCP.. the technical issue raised strikes be a more
appropriate for BCP.

The trunk group use draft will be re-written.

Exactly. Which is really the issue here. Why register a new Enumservice for
"trunk" when there is considerable evidence that is not needed. Demonstrate
how to incorporate trunk group data in ENUM requests in a simple BCP.

My intention was to consult with the AD on this in SF but my basic proposal
would be to request WG consensus to drop the original 'trunk group
Enumservice registration draft' and use the new 'trunk group use in ENUM' as
the basis for the technical solution. 

The issue raised here is a real problem. We will assist service providers
greatly by pushing this along. If we don't do it will end up as a individual
draft and wander in the wilderness. I've polled the SPEERMINT WG chairs and
they agree it would be better if the ENUM WG deals with this.
