IPv6 Deployment in Korea: Progress, Challenges, and Future Plans

1. `` `` `` IPv6 Status in Korea 2009. 3.4 IPv6 session, APAN27th meeting Joonhyung Lim (jhlim@nida.or.kr) National Internet Development Agency of Korea

2. Overview I Brief history of IPv6 in Korea II What we did in 2008 III What we are going to do in 2009

3. Introduction of speaker • 9 years in NIDA, including • 4 years as a security specialist for DNS and other internet system • 2 years as a researcher for ‘Telephone Number Mapping (ENUM)’ • I wrote related ‘internet-draft’, and became a author of ‘RFC5346 Operational Requirements for ENUM-Based Softswitch Use’in 2008. • 3 years as a researcher forIPv6 deployment project • My organization (NIDA) has been managing .kr domain name and IP address, and doing several government R&D project under Korea Communications Commission (KCC).

4. A brief history of IPv6 in Korea 2003~ ‘IPv6 Promotion plan I’ was announced ‘IPv6 strategy council (chairman: Minister of MIC)’ was established Phase1 R&D 2006.9 IPv6 requirement was contained as one of provisions in EA law 2004~2007 KOREAv6 Trial Service (25 projects ) 2008.3 By reformation of government, Korea Communications Commission (KCC) was key player for IPv6 promotion Phase2 Implementation 2008 KCC support 16 local governments and research institutions to build IPv6/IPv4 backbone network. 2009~ ISP’s backbone network will have been changing IPv4/IPv6 ready network by 2011

5. Related policy • In 2006, according to ‘The Law about acquisition and operation of Information system’, official notification was announced that every public agency must require IPv6 capable device when it purchase a communication H/W. • ‘2008 Guideline for execution of the budget’ from Ministry of strategy and finance, also includes a following direction. • Hardware that used for developing a information system must support IPv4/IPv6 capability.

6. What we did in 2008 –‘IPv6 deployment in public sector’ • For local governments • NIDA provided routers and firewalls to 8 local governments. • Each local government builds its IPv6/IPv4 network, and provides IPv6 web service as a public service. • Training course was organized, and about 500 people from 160 public organizationsare trained. • For Research institutes (Daedeok INNOPOLIS IPv6 Cluster development) • NIDA provided routers and firewalls to 8 research institutes. • Technical consulting service was provided to each research institute.

7. What we did in 2008 – ‘Ripple effect & New strategy’ • One of Korean major ISP enabled IPv6 on its backbone network for public sector. • Local government asked IPv6 connectivity to ISP officially  ISP made a quick decision to enable IPv6 because there is customer’s demand • Even though IPv6 wasn’t enabled all of area nodes, this work was very meaningful because it shows ISP might move if there is a customer’s demand. ISP ISP No service demand No investment investment Breaking deadlock by considering demand and supply matter No connectivity Demand for Service Provides Connectivity Negative circle Positive circle Private/public organization User User Private/public organization No service use Use service No Investment IPv6 transition on public sector

8. Transition plan • KCC announced “3-year Plan for promotion and management of internet address resources” in Dec. 2008. • According to the plan, Korea government will have implemented IPv6 on ISP’s backbone network by 2011, as well as public sector by 2013 • Major action plan for the next 3 years • ‘IPv6 transition committee’ will be organized with government and major ISPs in this year for cooperating with ISPs and commercial sector. • Government will investigate to add a IPv6 mandatory provision on their guideline about budget composition. If so, every government, local government and related organization will be influenced when they composite ICT budget. • To facilitate IPv6 transition, trial that secures IPv6 routing path on real ISP’s network, will be organized with government and ISPs. • Training and public relation activities are also going on constantly.

9. IPv6 transition committee • Chairman : Standing commissioner of KCC • Private area • Cooperation for increasing readiness of IPv6 at backbone network • Participants • CEO of Major ISPs, IX, vendor, etc • Public area • Establish a IPv6 transition plan for public sector • Participants (draft) • Ministry of public administration and security • Ministry of strategy and finance • National Intelligence Service

10. What we are going to do in 2009 – ISP trial • Objectives • Expanding IPv6 routing path by applying IPv6 to ISP and IX • Establishing a IPv6 network infrastructure that can provide IPv6 service to customer • Verifying technology and identifying a problem for scalable deployment • ‘IPv6 special zone’ that is able to make end-to-end IPv6 connection, will be established for verification of full routing path through dual stack network. • For verifying end-to-end connection, multiple IPv6 special zone will be activated by multiple ISPs. • ISP must enable IPv6 network on its backbone and access network for providing IPv6 connectivity at IPv6 special zone. • Each ISP must have IPv6 peer connection with IX or other ISP.

11. Background –“Why does backbone network needs to be change first?” • For several years, ISP’s backbone network has been slowly changing to IPv4/IPv6 dual stack. • If there are no IPv6 backbone network, IPv6 supported content provider’s network is useless. • To make sure path between client and IPv6 contents, now ISP’s backbone network must be changed to IPv4/Ipv6 dual stack

15. Timeline for IPv6 trial in 2009 • Apr. : ISPs will be selected by evaluating their proposal. • Oct. : IPv6 special zone will have been built in each ISPs coverage. • Nov. : Peering with 6NGIX *It’s subject to change as the project moves forward.
