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

Korean IPv6 Network

• Experimental IPv6 Network– 6Bone-KR (since 1998) *www.6bone.ne.kr

• Research & Education IPv6 Network– KOREN IPv6 Network (Since 1999)– KREONET2 IPv6 Network (Since 1999)– TEIN IPv6 Network (Since 2001) 6GN (Gigabit IPv6 Infrastructure) (Since

2004)• IPv6 Internet Exchange

– 6NGIX (IPv6 Next Generation Internet Exchange) (Since 2001)

• Commercial IPv6 Network & Trials– Pre-Commercial IPv6 networks – KOREAv6 Pilot Project Network (Since 2004)

III. Recent Activities on IPv6

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– 2007.6 Recruit members for ET-SHIM6 Test &

Distribute executable ET-SHIM6 code (Complete)– 2007.7 Construct the test environments

(Complete)– 2007.8 Local test (Complete)– 2007.9 Remote test– 2007.10 Feed back or extended studies– 2007.11 Final Reports for the ET-SHIM6 test

III. Future Plan (for ET-SHIM6 deployment)

16

Progress & Future works• Current Progress

– Completed Local test– Ready to Remote test

• Install ET-SHIM6 server for supporting streaming server

• Future works– Analysis of Test Results

• Measurements & Performance

– Report to Shim6 WG in IETF– New Test of ET-SHIM6 Release II

• ET-SHIM6 Release II: Kernel-based module

– Mobility Expansion Work• Modify ET-SHIM6 code to support Mobility
