Re: [Modern] Fwd: [new-work] WG Review: Managing, Ordering, Distributing, Exposing, & Registering telephone Numbers (modern)

["McGarry, Tom" <[e-mail]>]

They most likely would be involved in deciding whether that use case can happen (one entity delegating numbers to another), but it is unlikely they would be involved in the actual interaction.  Even if there are cases where they would, there are certainly cases where they wouldn't.  This is why the solutions need to be flexible enough to account for different policies.

A “VoIP service provider who wants to receive a block of new numbers through a delegation from a carrier” might well be subject to national regulation, so the national regulator might well be involved in that use case.

One would be an enterprise IP phone that has just been deployed and wants to acquire a new number from an IP PBX. Another would be a VoIP service provider who wants to receive a block of new numbers through a delegation from a carrier. I ran through such use cases at the MODERN BoF.

“Many use cases under consideration would not have a national regulator as an actor.”  - J. Peterson

I’ve struggled with this point.  What are the “many” use cases?  For example, I’ve not been able to envision the use case that would require a device to use a MODERN protocol tool to acquire an RFC 3966 telephone number.  What is this use case?

This continues to baffle me.  Why is the IETF proposing to develop protocol tools to manage telephone numbers?  What is broken about the existing system(s)?

And I really struggle with how this is supposed to work because there are so many different kinds of telephone numbers such as service numbers (e.g., 211, 911, etc.), Toll Free numbers, mobile numbers, wireline numbers, TLDNs, IMRNs, ported numbers, and multiple administrative databases, NPAC, LERG, SMS800, et cetera.

And the administration is distributed (in the US) at national and state levels.

Has anyone from any of the US or international number management administrative organizations requested that the IETF build tools for them?  If they don’t use them, who will?  And how can they integrate with an existing system?  Sorry Jon.  Still lost.

Your arguments here could equally well be applied to any important resource on which the IETF does protocol work - like, say, the DNS. The IETF manages the DNS protocol and publishes RFCs about it. But since national authorities are responsible for ccTLDs, surely the IETF is not a suitable body for managing the DNS! And it isn't. But it is a suitable body for managing the protocol work on the DNS. Other, effectively unrelated entities handle the administrative dimensions of operating the DNS, and yes, at those bodies there are lots of national regulators and they worry about the sorts of things you are worrying about here. The IETF just produces tools, and that is all MODERN proposes to do. Trying to characterize this effort otherwise is simply an error.

All work at the IETF is done by a coalition of the willing. If it turns out that the coalition is not representative of the needs of the community, then what happens? Well, the work built here doesn't get used. The only people who wasted any time or effort were the members of that coalition. No national interests can possibly be harmed by that, even if the failed work involved ways of talking about telephone numbers. This makes the IETF really different from places like the ITU, where the products of work have some binding effect on the world.

Virtually all proposed work at the IETF also faces a coalition of the unwilling. People who aren't interested, or who think the work should be done elsewhere, or that the work simply shouldn't be done at all. But I maintain your "formal objection" treats the scope of the proposed work as being different than it is, and I'd agree that if this proposed work required regulatory oversight, that the IETF shouldn't do it. But we're just building some protocol tools. There is also related work here for ATIS to do, and I'm sure ATIS or some other body could later take some the protocol tools developed in the IETF and conduct an experiment with various carriers to see if it works for that interest group or not, and that would be interesting information. But the IETF doesn't do that part, and doesn't aspire to do that part.

Finally, I'm not really sure how much I would expect "national regulators" to literally use the tools proposed in this work. They are tools for the use of a diverse industry of enterprises, carriers, end users, and so on. Many use cases under consideration would not have a national regulator as an actor. This work was in part instigated by an FCC workshop, yes, and someone associated with the FCC spoke at the MODERN BoF. But I don't anticipate that the FCC would be propping up servers to deploy this work - surely they would leave that to industry.

Thank you for this clarification.

Since the intent is to create tools and solutions that would be used by national regulators, presumably they should be involved in the development of the tools.

As far as I know, national regulators from most countries don’t normally participate in the IETF, for a number of reasons, including the IETF’s decision-making process and the fact that the IETF works in English. National regulators do participate in ITU-T, for a number of reasons, including the ITU’s decision-making process and the fact that documents are translated into the six UN languages before they are formally approved (and some discussions takes place with interpretation in six languages).

If the intent is to develop tools that would be used only in the USA at first, then I would suggest that it would be more appropriate to develop them in a forum such as ATIS or an ad-hoc group created specifically for the purpose. If the US experience proved successful, then the tools could be proposed for adoption elsewhere, for example through ITU-T.

If the intent is to develop tools for use in many countries right at the start, then I would suggest that the appropriate forum would be ITU-T, not IETF, for the reasons outlined above.

Thus, I formally object to the creation of this new working group, and this even if the Charter is modified as suggested below.

Please see additional comments inline.

Thanks and best,
Richard

This effort is intended to create tools and solutions to enable flexibility in the process of managing numbers among national administrators, service and application providers, and consumers.  Entities can choose to use these tools or not.  These tools are not for the ITU-T's processes or role, nor for how national administrators interact with the ITU-T.  But of course we want your input and feedback, so thanks for sending this along.  More comments in line below.

Dear Sir/Madam,

Below please find comments from the ITU Telecommunication Standardization Bureau on the proposed IETF working group MODERN.

1. Potential impacts on Recommendation ITU-T E.164 and E.164.1
It is stated at the beginning of the Charter that the MODERN working group will define a set of Internet-based mechanisms for the purposes of managing and resolving telephone numbers (TNs) in an IP environment. And it is mentioned that TNs are defined in RFC 3966 "The tel URI for Telephone Numbers". Does that mean the mechanism being referred to here only deals with Tel URI? Would there be any impact on Recommendation ITU-E E.164 and E.164.1 which are core recommendations on Telephone Numbers?
There will be no impacts on E.164 and E.164.1.

>RH: Given the scope of the work, I think that it is too early to say whether there would be an impact. Those Recommendations are regularly updated, in particular E.164.1, so there is nothing wrong with envisaging changes, with the recognition of course that the changes would have to be proposed to ITI-T Study Group 2 and agreed by that group.

2. Entities participating in the defined mechanisms
The Charter states that the protocol mechanism for resolving TNs will allow entities such as service providers, devices, and applications to access data related to TNs. But it is not clear what kind of entities can participate in the mechanisms defined by this MODERN working group. Would it be restricted to the entities who have been assigned a TN or a block of TNS?
Who participates in numbering processes within countries is subject to regulation.  The WG cannot make any decisions with regard to this.  I expect the WG to define "roles" within the number management processes; e.g., administrator, telecom carrier, application provider, consumer, etc.; and how those roles could interact with each other.  This will be a baseline for what tools and solutions would be useful to facilitate those interactions.

>RH: Even that might be subject to, or affect, national regulations.  That is, the definition of a “role” may well depend on national regulations.

3. Status of Telephone numbers in the defined mechanisms
Several operations related to TNs are mentioned in the Charter, including requesting, acquiring, resolving and associating. It is also stated that the protocol mechanism for acquiring TNs will provide an enrollment process for the entities that use and manage TNs. Does that mean Telephone numbers with various status, such as assigned, spare and reclaimed numbers will all be managed in the mechanisms defined by the MODERN working group?
I would expect proposed solutions to be able to address the status of a telephone number.

>RH: Since the terms “assigned”, “spare” and “reclaimed” are defined in ITU-T Recommendations (albeit sometimes implicitly), addressing the status of a telephone number might well impact E.164 or E.164.1.

4. Regulatory issues
The Charter states that Solutions and mechanisms created by the working group will be flexible enough to accommodate different policies for TN assignment and management, for example those established by different regulatory agencies. We would like to bring your attention to the fact that the E.164 international public telecommunication numbering plan is a politically significant numbering resource with direct implications on national sovereignty. ITU Plenipotentiary Conference Resolution 133 (Rev. BUSAN, 2014) recognized "the existing role and sovereignty of ITU Member States with respect to allocation and management of their country code numbering resources as enshrined in Recommendation ITU-T E.164", and further instructed the ITU Secretary-General and the Directors of three Bureaux (Telecommunication Standardization, Development, and Radiocommunication) to "take any necessary action to ensure the sovereignty of ITU Member States with regard to Recommendation ITU-T E.164 numbering plans whatever the application in which they are used".
We are aware of Resolution 133 and will certainly respect it.  I would propose adding the following text after the first sentence in the last full paragraph – "The group acknowledges ITU Plenipotentiary Conference Resolution 133 which recognizes the existing role and sovereignty of ITU Member States with respect to allocation and management of their country code numbering resources as enshrined in Recommendation ITU-T E.164."

>RH: That certainly would be a helpful addition. In addition to the above, I would suggest adding “The group’s outputs would be consistent with the provisions of relevant ITU-T Recommendations, in particular E.164, E.164.1, E.190 and the Recommendations referenced therein.”

>RH: For the sake of clarity I reiterate that I oppose the creation of this group even if the Charter is modified to include the text above.


5. Relationship with .Tel
DNS-based use of international numbering resources has been discussed in ITU-T Study Group 2 (SG2) since its meeting of 17-26 September 2013. TSB Director has also exchanged letters with ICANN on issues related to registering digit strings in the .TEL domain. A representative from ICANN participated in the ITU-T SG2 meeting (28 May - June 2014) and provided some background on the TELNIC application. A correspondence group under ITU-T SG2 was also set up in this regard. We would like to know how the work of this new WG would relate to issues related to registering digit strings in the .TEL domain and other DNS-based use of telephone numbers.
The WG will not create any new namespace that would require regulatory oversight, e.g., a new TLD, SLD, etc.  I wouldn't rule out the WG leveraging existing namespaces as part of proposed solutions.  But it's too early to say anything specific about that.  There is nothing in the charter that references .tel.

6. Relationship with related existing or concluded WGs
It is stated in the Charter that the working group will take into consideration existing IETF work including STIR, ENUM, SPEERMINT, DRINKS and SCIM. Detailed description of the relationship between this new WG and the above mentioned other existing or concluded WGs would be appreciated.
I agree.  I would modify that sentence to add the following at the end - "as well as other relevant industry and standards organizations."

7. The name of this new WG
The name of this new WG is "Managing, Ordering, Distributing, Exposing, & Registering telephone Numbers (modern)". But in the Charter, ordering, exposing and registering TNs are not mentioned, which seems to be a little bit inconsistent.
The IETF often has fun with creating WG names.  : )  But the charter is where to look for the scope of work.  The charter uses the following phrases "distribution, acquisition and management of TNs", "functions involved in associating information … with TNs", "associating, acquiring and resolving TNs", "access data related to TNs", and "mechanisms for resolving information related to TNs".  The functions you believe were left out of the charter will be part of one or more of these processes.

Charter:

The MODERN working group will define a set of Internet-based mechanisms for the purposes of managing and resolving telephone numbers (TNs) in an IP environment. Devices, applications, and network tools increasingly need to manage TNs, including requesting and acquiring TN delegations from authorities. The output of the working group should make distribution, acquisition, and management of TNs simpler for all entities involved.

The working group will define an information management framework for the roles and functions involved in associating information with one or more TNs in an IP environment.  The working group will also identify protocol mechanisms to support the interactions between the functions defined by the framework. This includes either recommending or defining protocol mechanisms for acquiring, associating and resolving TNs, with a preference for use of existing protocol mechanisms. TNs may either be managed in a hierarchical tree, or in a distributed registry. The protocol mechanism for acquiring TNs will provide an enrollment process for the entities that use and manage TNs.

The protocol mechanism for resolving TNs will allow entities such as service providers, devices, and applications to access data related to TNs. Maintaining reliability, real-time application performance, and security and privacy for both the data and the protocol interactions are primary considerations. The working group will take into consideration existing IETF work including STIR, ENUM, SPEERMINT, DRINKS and SCIM.

The work of this group will focus on TNs, as defined in RFC3966, and blocks of TNs, that are used to initiate communication with another user of a service. There is an expectation that aspects of the architecture and protocols defined by the working group will be reusable for other user-focused identifiers. Any such extensions or reuse of MODERN mechanisms are out of scope for the MODERN working group. Solutions and mechanisms created by the working group will be flexible enough to accommodate different policies for TN assignment and management, for example those established by different regulatory agencies.

The working group will deliver the following:

- An architecture overview, including high level requirements and security/privacy considerations

- A description of the enrollment processes for existing and new TNs including any modifications to metadata related to those TNs

- A description of protocol mechanisms for accessing contact information associated with enrollments

- A description of mechanisms for resolving information related to TNs

Milestones:

TBD
