Meeting Objectives

Agenda

• ENUM Essentials

• e164.org
• ...
• Proposal to TF-VVC / TNC 2006

ENUM Essentials

• Bernie did a presentation, explaining his
  experience in the implementation of ENUM in
  Switzerland
• During the presentation, the participants
  discussed the topics and exchange experiences

6
ENUM definition

• ENUM was defined to be implemented in the arpa
  tree
• All the other ENUM trees (E164.org or nrenum.net)
  are considered private trees.
• NRENs arent Telco Carriers, therefor should not
  use Carrier ENUM

7
ENUM trees

• The participants agreed that the slow development
  of the arpa tree is making it unusable, and we
  have to search for alternatives.... At lest for
  now
• It was said that was important to start using
  ENUM now, and we cant wait for the arpa tree
  delegation

8
ENUM trees 2

• All agreed that searching in more then 4 trees
  would be too much.
• Erik had the idea of a central proxy that could
  search a lot of ENUM trees.
• DNAME resource record, was tested and it works
• ISN Internet2 Numbering Scheme (ENUM like)
• Other solution presented was a private ENUM tree
  for NRENs (nrenum.net).

9
Why not e164.org

• Pros
• Good web interface
• Lightweight structure / management / provisioning
  / validation function / open to all
• Cons
• Open to all
• Unknown developments
• No formal connections to the NRENs
• Not trustable

10
NRENUM.net

• Bernie proposed a private ENUM tree NRENUM.net
• This tree should be controlled by the NRENS and
  used in the countries where the arpa tree is
  unavailable
• NRENUM.net delegations are delivered to the
  NRENs, and the NRENs can decide how and who to
  register.
• NRENs trust between them selfs

11
NRENUM.net

• Michal Krsek (CESNET) defended the exclusive use
  of the arpa tree, with the exception of the
  nrenum.net in the countries without arpa
• Marco Sommani (CNR) reported the slow
  implementation of ENUM in Italy. He is very
  interested in the use of NRENUM.net

12
Billing

• In Switzerland they are not billing for the ENUM
  registers, but this may be done in the future.
• Rui proposed that the billing should be made by
  resource record and not by telephone number
• The participants agreed

13
Proposal to the TNC

• The chosen trees (and lookup order) decided in
  this meeting are
• 1. e164.arpa
• 2. nrenum.net
• This list is going to be presented in TNC 2006

14
AOB

• The VoIP meetings/group should continue even if
  no TF-VVC sucessor
• Other systems may be used
• nrenum.net website
• Mailling lists
• WebGroup engines

15
Conclusion

• ENUM is the solution for dynamic routing
• People want to use arpa, but it is tied up in
  politics
• NRENUM can be the transitory solution and good
  for training the future arpa introduction
