So ... all in favor of re chartering the ENUM WG ..please hum on this list
or the ENUM WG list now attached.

Its time to force the issue. This is important work ultimately central to
making SIP work better. Stall and delay is not a rational option here. SIP
Service providers and IMS providers want clarity and direction on where the
technical standards are moving, if at all. If the IETF doesn't do this it
will be done privately and without proper community and peer review.

They're consistent with the approach in Bernie's draft.

However on the last call the it was proposed that it might be a good
idea to simply reboot the ENUM WG.  In another message Richard has shown
that much (if not all) of what we want to do is _already_ within charter.

[[[
I first proposed E2M during the Dublin IETF, as a way to mitigate concerns
that a particular ex-AD had over use of E2U for "non-communications data".
AFAICR he was OK with this proposal, which then laid dormant until Bernie
wrote it up.

For my own Send-N draft, my plan had actually been to simply wait for the
ENUM Services Guide draft to become an RFC, and the re-file under the expert
review process.

As an individual I see it a viable way to work out at least parts of the 
E2MD cases in the ENUM WG (once we've sorted out which parts are 
suitable). In this case E2MD would continue to work on those parts that 
are not suitable for ENUM.

As a co-chair of the ENUM WG the appropriate answer to this consultative 
hum from Rich is: abstention

cheers,
  Bernie

I don't believe IETF should be afraid if others decide to take IETF =
stuff and do their own take with it. That is not a good reason to do =
those carbuncle things In IETF. What is a good reason is if the WG is =
taking the initiative and doing work that is for everyone, scales and =
isn't just trying to satisfy a need in some walled garden.=20

So what would be the workplan? Apologies if I've missed a draft that =

DNS technology Dean !!! ..stop this "It's the DNS" thing.  Its not about the
DNS it never was. You are perpetuating the problem once again. 

If you note the ENUM charter we never ever used the word DNS. That was
deliberate and calculated when I wrote it. 

Delete the word DNS from your text and it closer to the reality here. Now of
course the solution is really the two variants of 3761 in deployment the
public trees and the private closed ones.  The use cases would reflect that
matrix of options. Indirection is NOT needed in closed systems its simply
interjects a redundant look up into the system that causes delay is session
set up. 

Goal of the E2MD Work (see how much better it reads when you don't talk
about the DNS :-) 
---------------------

An easily extensible framework for using the DNS to discover data that 
is related to an E.164 number. The 
framework's organizational model is expected to be based as closely as 
possible on the existing ENUM [RFC 3761 framework] . The framework is
expected to 
provide for a multiplicity of different data types and provide for a 
semantic definition of each data type as well as define its relationship 
with the aforementioned E.164 number. The framework is expected to 
provide for storing some data types directly, and in other 
cases to store a reference to the data, with that 
determination based on the nature of the data type and its use cases.

The framework is NOT expected to provide a selective query mechanism; 
rather, a query for framework data associated with an E.164 number 
is expected to return all such data and data. The framework's query
mechanism will make no considerations 
for authentication, authorization, or selective response based on the 
identity of the querying node. Further, the framework's mechanism 
is expected to make no considerations for network congestion, 
reliability, integrity, privacy, or overly-large response sets.

Where such considerations are significant, the framework is expected to 
provide guidance on the use of other protocols that will be used to 
retrieve the framework data referenced , and such other 
protocols are expected to provide needed considerations for 
authentication, authorization, selective response based on the identity 
of the querying node, network congestion, reliability, integrity, 
privacy, and large responses. The framework is expected to provide for 
standardization and IANA registration of new data types without a 
requirement for IETF consensus on each new data type, using the existing 
ENUM service registration model.

Subject: [e2md] E2MD and Indirection -- a new problem statement


I've heard Ray and Richard say that indirection might be appropriate in
some cases. If we're willing to factor that into the work, we might have 
an opportunity.

If we amended our problem statement to say that we would analyze the
initial use cases, determine which cases need to be "in the database"
and which need to be indirectly referenced, show how to indirectly
reference where needed, and provide guidance for future users on how to
make this determination and provide future guidance on dereferencing,
then I predict our problem statement would be MUCH more palatable to the 
opposition.

Let's try a re-write of my proxy-shill version and see if it gets
friendlier looking. This one's a bit rough, but it should convey the basics:

Goal of the E2MD Work
---------------------

An easily extensible framework for using the DNS to discover data that 
is related to an E.164 number also resolvable in the DNS. The 
framework's organizational model is expected to be based as closely as 
possible on the existing ENUM framework. The framework is expected to 
provide for a multiplicity of different data types and provide for a 
semantic definition of each data type as well as define its relationship

provide for storing some data types directly in the DNS, and in other 
cases to store a reference to the data in the DNS, with that 
determination based on the nature of the data type and its use cases.

The framework is NOT expected to provide a selective query mechanism; 
rather, a DNS query for framework data associated with an E.164 number 
is expected to return all such data and data references known by the DNS 
to the querying node. The framework's expected query mechanism is 
expected to be straight-up DNS, and as such will make no considerations 
for authentication, authorization, or selective response based on the 
identity of the querying node. Further, the framework's query mechanism 
is expected to make no considerations for network congestion, 
reliability, integrity, privacy, or overly-large response sets beyond 
the inherent mechanisms of the DNS.

Where such considerations are significant, the framework is expected to 
provide guidance on the use of other protocols that will be used to 
retrieve the framework data referenced from the DNS, and such other 
protocols are expected to provide needed considerations for 
authentication, authorization, selective response based on the identity 
of the querying node, network congestion, reliability, integrity, 
privacy, and large responses. The framework is expected to provide for 
standardization and IANA registration of new data types without a 
requirement for IETF consensus on each new data type, using the existing

Dude! Slow down and get this through your head: As far as the "rest of
the IETF" is concerned, ENUM is about putting phone numbers in the DNS,
and as long as ENUM relies on the core protocol of the DNS, any
extension to ENUM is an extension to the DNS.

Failure to understand this very fundamental concept is why we don't
understand the objections that Olaf and Peter and John and Jon and other
DNS people keep bringing up. And it's why "just restarting the ENUM
working group" will not solve the E2MD problem: the same people that are
objecting to E2MD as a standalone working group will object to
restarting ENUM. This is also why the CNAM draft that "had consensus in
ENUM" did NOT advance through the IETF and is not currently "a
standard." If the approach was ever going to fly, it would have migrated
south for the winter years ago!

Either solve the problem in a way that is acceptable to "the DNS people"
 by using the DNS consistently with their guidelines, or move the
problem outside the DNS. Trying to shove it down their throats is just
going to perpetuate further non-progress.

Well said.  The OID Resolution Sytem (ORS) folks ran into
the same pushback from the "DNS people," even when a
similar instantiation occurred with ONS.

hum, as a "DNS person"... I spent a fair number of hours ~70% of my time,
working on something almost identical to the VSGN-ONS platform ... with the
AutoID labs folks in Japan.  We never called it anything other than what
it was, DNS with extentions.   Never remember any public pushback from the
"DNS people" on ONS.  Archives?

As Gonzalo already pointed out this part of 3761bis needs revision before
it goes to IESG.

Section 1.2. appears at best "confusing"...or should I rather say 
"broken", as it mixes up private ENUM instances that are based on the 
E.164 dial plan and those private instances that do not use E.164 numbers.

    If these mechanisms are re-used, the suffix used for the private
    dialing plan MUST NOT be e164.arpa, to avoid conflict with this
    specification.  Parties to the private dialing plan will need to know
    the suffix used by their private dialing plan for correct operation
    of these mechanisms.  Further, the application unique string used
    SHOULD be the full number as specified, but without the leading '+',
    and such private use MUST NOT be called "ENUM" because the leading
    "E" in this acronym explicitly stands for "E.164".


Section 2 on the other hand makes it practically impossible to use ENUM 
with non-E.164 numbering plans:

   To mitigate this risk, the "E2U" token MUST NOT
   provisioned in domains associated with non-E.164 numbers.


Furthermore I am not sure if the introcuction section is the right place 
to make mandatory statements. IMHO It should be rather an applicability 
statement section or similar.


Note: I understand you inherited this part from RFC 3761.

cheers,
  Bernie

It all depends on what we mean by ENUM. We do not agree if ENUM stands  
only for the technology (look things up in dns, given some root) or  
only when the root is e164.arpa.

I thought we had this discussion in the enum wg, and concluded that  
enum (without any prefix or suffix) always implies use of e164.arpa.

Other things are called infrastructure enum, enum-like, use of enum  
technology, private enum or such.

Which I think is what the text quoted says.

Hi Patrik, folks,
 That's my problem -- there are two elements: the technology (mapping =
phone numbers to domain names within SOME apex) and the IAB/ITU-T+IANA =
agreement on e164.arpa.
The technology is usable regardless of whether it's in public or within =
a private federated net, or using an alternative root, or ...

This is not just a name (ENUM =3D=3D use of this technology in public =
within the e164.arpa apex). It's also who or what can use the =
technology.
This matters for Send-N and Unused, where there may be records elsewhere =
that in leaf zones associated with E.164 numbers.

The technology is common; the restrictions on E.164 numbers are tied to =
the IAB agreement. We have a mixture of the two.

all the best,
  Lawrence

Hi again Patrik, Bernie, folks,

Patrik? -- help needed.

The issue in section 2 of RFC 3761 (bis) that it doe not have the =
intended effect as specified.

It is perfectly possible to have E2U NAPTRs in other domains -- an ENUM =
domain can hold a non-terminal NAPTR that points to any other domain. =
That domain can hold E2U NAPTRs. Thus:
     $ORIGIN 3.8.0.0.6.9.2.3.6.1.4.4.e164.arpa.
      NAPTR 100 50 "" "" ""    .

     $ORIGIN example.com.
      NAPTR 100 50 "u" "E2U+sip"
          "!^(\\+441632960083)$!sip:\\1@example.com!"    .
...

This seems valid, BUT it doesn't match the text -- example.com. is =
certainly NOT associated with an E.164 number, but could hold NAPTRs =
that were discovered as part of an ENUM query on the E.164 number =
+44-1632-960083

I would like to re-write this paragraph, as I do not believe that this =
block on reasonable use was the intention of the last sentence.
i.e. I think it's wrong as written.

I've looked back through the ML archives, and I didn't get the =
impression that this was was was intended. (I sure don't remember it =
that way).

I also think this paragraph is broken in other ways; it conflates ENUM =
domains (i.e. input is an E.164 number, key is within the e164.arpa =
apex) with E2U NAPTRs, dialling plans with number plans, and diallable =
numbers with assigned numbers in a number plan, and ...)

Comments?

all the best,
  Lawrence

Well .. as far as I'm concerned the discussion of what is the namespace is
charming but ultimately another discussion. What is important is the
definition of the use case and why opaque carrier identification
methodologies is important (vs edge URI identification) and I'd like to call
for volunteers to help me or someone to write this up as a ID.  There is no
possible doubt that this is important to the global telecommunications
industry and IMHO is principally utilized principally in
private-carrier-infrastructure ENUM instantiations. 

Not to say that, by some for form of indirection, this could live in
e164.arpa but either way it makes sense. It's the right thing to do and the
timing is right now.

When we speak about OIDs here, we are speaking of OIDs formed via the IANA
Enterprise Numbers, correct (1.3.6.1.4...)? If so, do we need an extra
string for all enterprises (1.3...) or can we just use the enterprise
number? And if we want a hierarchy, it can always be constructed underneath
the IANA Enterprise number, no?

As Penn wisely points out, this can be discussed in detail in the
appropriate forum at the appropriate time, however, ....

The ITUs OID looks like a good option.  It seems to meet the following
requirements/advantages:

1) It already exists; no need to invent and debate a new scheme, approach,
documentation set, etc.
2) It is hierarchical; organizations can optionally create sub-OIDs (or sub
trees) under their main OID if they need to.
3) The sub-identifiers under the main identifier can be opaque; they need
not have a known, or the same known, meaning to all parties that may use/see
them
4) There is an existing urn that _might_ be useful "urn:oid"
5) If the set of existing OIDs already allocated under one of the existing
OID trees (e.g. 1.3.6.1.4) are not appropriate then it seems that an
organization (e.g. IANA) can be formally delegated the responsibility of
dolling out (similar to the way that it doles out Enterprise Numbers) the
OIDs under a new OID tree.  IOW, the OID tree it centrally managed, but the
management of sub-trees can be delegated.
6) They are cleanly parseable by a computer or a human; their form is
standardized and well structured.

A disadvantage, however, is that ITU OIDs can theoretically be fairly long
(in contrast to the 4 characters that comprise a north american OCN or SPID,
or the handful of digits that comprise the IANA Enterprise Number).  But it
is not clear to me whether in practice, given our use case, if they will
ever be as long as they can theoretically be.  The spec for our usage would
just need to address this point.

Hi Penn,

Good choice.  However, the text needs tweaking to read:

   Use RFC 3761 technology to provide for the Carrier of
   Record for an E.164 number (as defined in RFC 5067) to
   publish the mapping of that E.164 number using an assigned
   Carrier of Record Object Identifier (OID)) such as an IANA
   Enterprise Number as defined in RFC 2578.  Ref. Rec.
   ITU-T Recs. X.660 and X.680.

The changes clarify what identifier is being specified and includes
reference to the authoritative OID standard.  It also allows for the
possibility of using other assigned OIDs for a Carrier of Record.  Although
more than 35,000 Enterprise Numbers have been registered with IANA, there
are many carriers who have OIDs that were registered with national
authorities for Carrier of Record purposes.  As long as there is a valid,
globally unique OID, some flexibility should exist.

For example, ATT has the OID 1.3.6.1.4.74 from IANA's OID block, but it also
has 0.7.7223 that it uses for some services in Argentina.

best,
tony

It is an example, and it says it is possible to have E2U NAPTR in other =

Examples are non-normative.

I do not see any problems with the text.

Though the use case for a G-SPN has been identified by this list and is on
the TWKI, I want to make it abundantly clear that I do not believe that ENUM
or a E2MD WG should actually define what is the appropriate namespace for
G-SPN's.

 

It is a requirement for DRINKS ( by ITU liaison) and touches on SPEERMINT (
which IMHO should shut down ). Consequently the logical thing to do is a
individual submission. 

 

I've offered to try and rough cut a Use Case and Requirements document,
which I will do in the not to distant future in collaboration with several
others who have offered to help.

Hi Richard,

Could you amplify on the "by ITU liaision" parenthetical?

Considering the G-SPN notion is being driven by a
NeuStar input into ITU-T, that creates a substantial
NeuStar new revenue opportunity/impact on providers,
chaired by a NeuStar staff member in ITU-T, and
sprinkled with NeuStar people in IETF, some care
seems appropriate about the assertions and process.

I'll offer to help as well.

cheers,
tony

Hi Richard,

Could you amplify on the "by ITU liaision" parenthetical?

I'ts simple ITU wanted to make sure the DRINKS WG left open a field for SPN
use.

http://www.itu.int/md/T09-SG02-090324-TD-PLEN-0071/en


Considering the G-SPN notion is being driven by a
NeuStar input into ITU-T, that creates a substantial
NeuStar new revenue opportunity/impact on providers,
chaired by a NeuStar staff member in ITU-T, and
sprinkled with NeuStar people in IETF, some care
seems appropriate about the assertions and process.

Well whether it creates any revenue for some company especially the one you
mention is none of my concern. :-) Whatever form the SPN takes, its self
evident that SPN create operational efficiencies for service providers both
for internal as well as external session establishment. 

I'll offer to help as well.

cheers,
tony

That's not really what the document says.  Since many people
may not be able to access the site and view it, the attached
copy is edifying.  Note particularly the highlighted text.  It
helps provide context and concern.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Telephone Number Mapping Working Group of the IETF.


	Title           : The E.164 to Uniform Resource Identifiers (URI) Dynamic Delegation Discovery System (DDDS) Application (ENUM)
	Author(s)       : S. Bradner, et al.
	Filename        : draft-ietf-enum-3761bis-07.txt
	Pages           : 21
	Date            : 2010-05-27

This document discusses the use of the Domain Name System (DNS) for
storage of data associated with E.164 numbers, and for resolving
those numbers into URIs that can be used (for example) in telephony
call setup.  This document also describes how the DNS can be used to
identify the services associated with an E.164 number.  This document
obsoletes RFC3761.

Hi Folks,
 To explain why we've issued a new version of 3761bis ...
Gonzalo provided a detailed review of the current (-6) draft.

I do not believe that we have made any changes to the formal text.
These changes are intended to clear up some of the text
to make it easier to understand (and make it shorter).

In response, we produced this new version.=20
- (very slightly) tweaked the text of 1 (intro) to reflect what ENUM
  does (or doesn't do). i.e. changed the statements that "ENUM stores
  E.164 numbers in DNS" to "providing storage in DNS associated with
  E.164 numbers".
 - changed the Abstract to reflect that.
 - tweaked the text of 1.2 to try to meet Gonzalo's review comment on it
   and to make it a bit clearer what is required for non-E.164 numbers
 - moved the arcane text that was paragraph 2 of section 2's =
introduction
   into its own sub-section at the *end* of section 2 ("Collision =
Avoidance").
 - removed some text copied from RFC 5483 and replaced with an =
informative
   reference to that RFC.

 We've also:
 - swapped around a couple of the items so the ORDER/PREF ones are all
   together,
 - have tried to answer Gonzalo's question "why is ORDER/PREF a =
problem?"
   by splitting out the proposed default value as a separate item and

Hi ENUM:ers

As Lawrence already indicated, draft-ietf-enum-3761bis has undergone 
quite some changes while implementing the AD review feedback.

Although these changes are considered editorial only, the ENUM WG should 
have chance to look over these changes and to object, if needed, before it 
goes to the IESG.

  http://www.ietf.org/internet-drafts/draft-ietf-enum-3761bis-07.txt

Please indicate any objections you might have to the latest version of 
draft-ietf-enum-3761bis no later than Wed, 2 June 2010 noon UT.

[In case you need more time, this deadline could be extended on 
well-grounded request. Beware, that this would add further overall 
delay in processing the 3 main ENUM WG documents in the AD queue.]

cheers,
  Bernie, Co-chair of the ENUM WG

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Telephone Number Mapping Working Group of the IETF.


 	Title           : The E.164 to Uniform Resource Identifiers (URI) Dynamic Delegation Discovery System (DDDS) Application (ENUM)
 	Author(s)       : S. Bradner, et al.
 	Filename        : draft-ietf-enum-3761bis-07.txt
 	Pages           : 21
 	Date            : 2010-05-27

This document discusses the use of the Domain Name System (DNS) for
storage of data associated with E.164 numbers, and for resolving
those numbers into URIs that can be used (for example) in telephony
call setup.  This document also describes how the DNS can be used to
identify the services associated with an E.164 number.  This document
obsoletes RFC3761.

Hi Lawrence,

thanks for putting this new revision together. I will give the WG a few
days to have a look at it in case somebody has comments (I will of
course also review this new version). After that, I will advance the
three documents in parallel.

Thanks,

Gonzalo
