TUESDAY

09:00 – 10:30

6. IPv6 Routing Update.
Gert Doering. Spacenet (20 min)

Update on observations on the state of the IPv6 default free routing table.

7. IPv6 Multihoming Status.
Kurtis Lindqvist. Netnod (30 min)

An up-to-date status report on the progress towards scalable IPv6 multihoming.

8. IPv6 Address Allocation
--An Alternative Algorithm for the Sparse Allocation Process.
Mei Wang (30 min)

IP address allocation policies significantly impact the Internet infrastructure, affecting many parties such as router manufacturers, ISPs, and end users. An address allocation policy can also directly affect the performance of the Internet.

For example, address fragmentation, a key problem in IPv4, degrades address lookup performance in routers. Thus, a well-designed address allocation policy needs to minimise fragmentation while using the address space efficiently.

This paper attempts to quantify the performance of address allocation policies by modelling key features that lead to fragmentation and inefficient address space usage.

Our main contributions are: (i) we identify a drawback of the current IPv6 address allocation policy, which treats all entities uniformly, (ii) we propose a scheme that takes future growth rate into account for allocations, and (iii) an analytical model for measuring the efficiency of allocation schemes, allowing us to quantify the improvement our proposal offers over the current scheme. We believe that a quantitative study of allocation policies is timely since IPv6 address allocation is just beginning in earnest.

11:00 – 12:30

9. AS Number Exhaustion and the 4Byte Transition Plan.
Geoff Huston, APNIC (20 min)

10. RIPE Policy Development Process.
Leo Vegoda, RIPE NCC (20 minutes)

Abstract: This presentation introduces RIPE's formalised Policy Development Procedure (PDP), as documented in "Policy Development Process in RIPE" (ripe-350). It explains the areas addressed by the PDP, the places in which discussions occur and how to become involved in creating RIPE Policy. Additionally, the presentation explains how the RIPE NCC, RIPE's secretariat, supports the process and the people proposing policies.

11. Today’s Challenges in Lawful Interception.
Carlo Rogialli (30 min)

Lawful interception over plain telephone traffic is a consolidated practice worldwide, granting safety and protection to many countries in the globe. The migration of the world’s communication bandwidth towards IP network and protocols poses many doubts and problems, either on the normative or the technical side.

Whilst CALEA and ETSI standards inherent to the Lawful Interception matters give a good overview of the minimum service level that may be requested by national authorities to ISPs and Telecom Operators, many aspects relevant to the network operator themselves still remain uncovered, those primarily involving several issues about network topologies, addressing, user identification, probing methodology, capture extent, decodification issues and responsibilities, captured traffic integrity, data usefulness.

The contribution primarily based upon the long-term experience over lawful interception in Italy tries to identify the major issues normally faced by the operators themselves and still proposes some service models that may fulfil the requirements from both authorities and Network Operators.

12. Introducing ENISA. Ronald de Bruijn. (20 min)

14:00 – 15:30

---------- ENUM track. ---------- (90 minutes)

13. Reasons for (not) Using EPP for ENUM Marcos Sanz, DENIC (20 min)

The recently published RFC 4114 defines an interface for the provisioning (creation, deletion, transfer...) of ENUM domains by means of the Extensible Provisioning Protocol (EPP).

This is relevant for registries which are going to provide this service. DENIC (the operator of the German TLD ".de" and delegee of the domain "9.4.e164.arpa") is not making use of this protocol for ENUM tier 1 registration services. Why?

14. ENUM Tier 2 Provisioning Techniques Adrian Georgescu, AG projects (20 min)

The ENUM Plugtests event held by ETSI proved that ENUM technology reached a stage where it is important to learn how to interoperate implementations that are now live in different countries and private networks.

It also showed that it is critical for a world-class solution of mapping E164 numbers into IP addressing schemes like ENUM to accommodate the requirements of all parties involved, namely operators, registries and end-users.
We have seen how the provisioning of ENUM entries has an impact upon how Voice over IP applications understand the ENUM data.

It is important the Tier 2 provisioning systems follow closely the standards and the existing best practices recommendations specified by ETSI and IETF documents. Most important, the ETSI Plugtests taught us how to improve these best practices and produced important feedback for the fine-tuning of the related standards.

The interface between Tier 2 and Tier 1 requires also attention and standardisation of registry interfaces can be a key enabler of rolling out ENUM.

15. ENUM Validation Scheme and process flow
Bernie Hoeneisen, SWITCH (20 min)

Validation has proven to be the main challenge in the transition from a trial to a ENUM production environment. To facilitate interoperability SWITCH and ENUM.AT have submitted 3 Internet Drafts dealing with several aspects of the validation process for ENUM delegations. On the last IETF (Paris) the ENUM WG decided that the these topics will become working group items. Therefore we will present an update on this work.

16. Panel discussion with the presenters and Andrzej Bartosiewicz,
NASK (30 min)

16:00 – approx. 17:00:

17. Combined User and Carrier ENUM under e164.arpa.
Michael Haberler (30 min)

Until recently the general assumption was that User ENUM would be operated under e164.arpa, under national regulatory involvement and user-opt-in, while infrastructure ENUM (carrier opt-in) would be under some other apex, or in a private address space altogether. However, substantial synergies and other benefits are enabled by operating both types of ENUM under the e164.arpa tree, among which are lower investment, higher resolution rates, and global coverage not limited to a single "club of carriers". Standardization of Carrier ENUM also fosters standards-based services, which is a benefit to service providers, and eventually customers, worldwide.

This talk outlines the current status of the IETF standards process, and the deployment roadmap for +43 as well as development in other countries.

18. Broadband, BcN (Korean version of NGN) and Wibro Deployments.
Jinhyoun Youn, KT (40 min)

19. Certificates and IP Addresses.
Geoff Huston, APNIC (30 min)

Applications of Cryptographic certificates in the context of Address Resource management.
