ICANN resolution

On the Deployment of IPv6

Whereas, the unallocated pool of IPv4 address space held by IANA and the Regional Internet Registries is projected to be fully distributed within a few years;

Whereas, the future growth of the Internet therefore increasingly depends on the availability and timely deployment of IPv6;

Whereas, the ICANN Board and community agree with the call to action from the Address Supporting Organization and the Number Resource Organization, Regional Internet Registries, the Government Advisory Committee, and others, to participate in raising awareness of this situation and promoting solutions;

The Board expresses its confidence in the Internet community to meet this challenge to its future prospects, and expresses its confidence in the bottom-up, inclusive, stakeholder-driven processes in place to provide any needed policy changes, and;

The Board further resolves to work with the Regional Internet Registries and other stakeholders to promote education and outreach, with the goal of supporting the future growth of the Internet by encouraging the timely deployment of IPv6.

From emergency to IPv6

• IPv6 is already there …– Internet v6 is there today :– NRENs in EU, North America, Asia … are interconnected in IPv6– Lots of IXP are offering IPv6 connectivity– ISPs and Telcos exchange IPv6 routes– Almost all operating system are IPv6 compliant

• Then the question is not “if” but “when” and “how” …



Why IPv6 now?

• IPv6 deployment will speed up in the remaining years:– Contact with China/India/Africa– Grid interoperability (COS, Naregi)– Being non IPv6 compliant will be seen as a blocking factor for

large scale new software deployment.– Only 3 years remaining before IPv6 will become mandatory!

Future work of SA2

• A comprehensive report on IPv6 programming language ( in C/C++, JAVA, Perl, Python)

• A report on the local usage (to the machine) of non IPv6 component like MySQL ( local socket instead of TCP/IP connection)

• Specific deep test for important external modules– Python/ZSI, Perl/SOAP::Lite, PostgreSQL– Unknown IPv6 status packages to be tested?

• New version of BDII• Submit bugs for non IPv6 compliant packages• Finalize the LD_PRELOAD based IPv6 checker

how organize the project collaboration on IPv6

- The outcome of this activity strongly depends on the effectiveness our collaboration - Organize a joint task between SA2 and JRA1

- JRA1 contribution is fundamental/crucial to provide new IPv6 compliant gLite components

- Organize a joint task between SA2 and SA3- without the validation process no IPv6 gLite distribution

- Joint task with ETICS (testing and building) is already set up- SA1, node installation and configuration?




What SA2 can provide to you?

• Two testbeds in (Paris/Rome) with almost all the type of gLite nodes to test the interplay between different nodes– Automated test of the interplay: ETICS– Specific test

• gLite dependencies – External dependencies

Assessment of IPv6 compliance of external modules Deep test for important external modules: Grid-FTP …

– Internal dependencies Code checker /Dynamic checker

• Wiki to unify all relative information about IPv6 compliance• Support for the IPv6 setting up in the developers site in order

to allow them to test• IPv6 presentation and tutorial activities




General project issues on IPv6

• Porting a code on IPv6 is an easy process– David Smith port a large component DPM-LFC in 2 weeks (Dec 2007)

– SA2 success also to port BDII quickly (Feb 2007)

– Java support IPv6 without any code update

– It seems that having a IPv6 compliance could be achieved in the scope of EGEE-III


• Which would be the best approach to move the gLite code to IPv6 compliance?

• Which would be the strategy for non compliant externals components?



SA2-JRA1 Collaboration

• A roadmap toward IPv6– Working group on IPv6– Next candidate component that could be ported on IPv6– How SA2 could provide support

Support for the IPv6 setting up the developers site in order to allow them to test

IPv6 Testbed: test the interplay with other nodes What for of access/usage suits the developers best

• External dependencies– Assessment of IPv6 compliance of external module– Deep test for important external modules: Grid-FTP– An official list

• A unique JRA1 interlocutor for SA2?• IPv6 presentation and tutorial activities

- All-Hands Meeting of JRA1?




SA2-SA3 Collaboration

• Support to deploy IPv6 within SA3 testbed

• How IPv6 can be included in the SA3 testbed?– Include SA2 machines in SA3 testbed– IPv6 communication between SA2 testbed and SA3 testbed

(CERN): tunnel

• A unique SA3 interlocutor for SA2?




Thank you.
