Roll Call Jan Ruzicka, Michal Krsek (CESNET) Erik Dobbelsteijn (SURFNET) Rui Ribeiro, Joao Pereira (FCCN) Antonio Pinizzotto, Marco Sommani (CNR) Bernie Hoeneisen, Bea Huber (SWITCH)

Meeting Objectives Discuss dynamic routing schemes, like ENUM, and choose a common platform to be used for all. To achieve a consensus in the way that ENUM is used and propose it in the TF- VVC meeting at TNC2006.

Agenda ENUM Essentials Bernie’s Presentation about ENUM ENUM Trees e164.arpa nrenum.net 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;

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. NREN’s aren’t Telco Carriers, therefor should not use Carrier ENUM;

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

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).

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

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. NREN’s trust between them selfs

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

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

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

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

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;
