3 I. About ANF IPv6 TF

4 About ANF IPv6 TF Background –ANF(Advanced Network Forum) should take lead in advanced networking with IPv6 by deploying high performance IPv6 infrastructure over R&E network in Korea. We provide the technical guidance for the deployment of IPv6 and promote the development of IPv6 applications. This is to aim to facilitate the IPv6 production service. Objectives –Deployment of Gigabit native IPv6 production service –Promotion and Facilitation of IPv6 network and applications Scopes –IPv6 Management Group Provide stable IPv6 services Coordinates IPv6 Network operation activities Provides a platform to test various IPv6 technologies and its applications among members –IPv6 Application Development Group Identify requirements for applications which could evidently benefit from IPv6 Facilitate research and development of new applications Strive to bridge the gap between IT experts and domain scientists Encourage and conduct collaboration or joint projects among participates

11 III. Recent Activities on IPv6

12 Multihoming test on 6GN (1/2) ‏ Overview –The test of verification of the site multihomed 6GN connected by KOREN and KREONET2 using the ET- SHIM6™ Occurs some failures included in primary link or ISP Check recovery progress for these failures using streaming service Introduction to ET-SHIM6™ test –A implementation of SHIM6 protocol, which is a solution in IETF for supporting site multihoming. –A Linux based application Base documents –draft-ietf-shim6-proto-05.txt and draft-ietf-shim6-failure- detection-05

13 Multihoming test on 6GN (2/2) ‏ Main Goals for Test –The verification and utilization of 6GN –The understanding of site multihoming environment on 6GN –The study of the new Internet architecture for separating Identifier and locator by using the SHIM6 protocol –The initiation work for expansion of multihoming and mobility protocol Milestone – Recruit members for ET-SHIM6 Test & Distribute executable ET-SHIM6 code (Complete) ‏ –2007.7Construct the test environments(Complete) ‏ –2007.8Local test(Complete) ‏ – Remote test – Feed back or extended studies – Final Reports for the ET-SHIM6 test
