Main IPv6 Driving Force – the Government
• MIC/NIA
– E-government communications network
– IPv6 deployment promotion council
• MGAHA
– E-government integrated network
• MND
– IPv6 deployment planned to be complete
by 2015

MIC/NIA’s IPv6 Strategies
• In the past
– Supporting only IPv6 technologies and
applications projects thru NIA
– Depending upon only telco’s for IPv6
deployment over their commercial networks
• Now (since 2005)
– Interested in real IPv6 applications,
contents, and users
– Formed IPv6 Deployment Promotion
Council this year
KT Future Technology
Laboratory
MIC/NIA’s KOREAv6 Project
• Goal
– increasing the recognition of IPv6,
expanding the IPv6 network and activating
the IPv6 service
• Many subprojects
– VoIP, WiBro, Home network, hdtv, medical,
etc
• http://koreav6.vsix.net
– Not much English introduction
KT Future Technology

MIC/NIA’s IPv6 Plan This Year
• System improvement
– IPv6 address allocation, DNS registration, etc
• Router development
– Flow-based router with mobility enabled
• Securing IPv6 users : over 200K this year
– Provide IPv6-based services of public institutions based on
its e-government communications network
– Building large-scale IPv6 wireless network
• 10M IPv6 users by 2010
• These goals are more or less related my group’s joint
projects with NIA
KT Future Technology
Laboratory
How about Telco’s
• Telco’s pushed for years by MIC to deploy
IPv6 over their commercial networks thru IPv6
strategy council driven by MIC
• No Telco’s are now ready to deploy IPv6 as
they see IPv6 as business, not as
infrastructure upgrade
• They’re still research-oriented even though
they have IPv6 deployment plans
– KT, SKT, etc
KT Future Technology
Laboratory
How about KT
• Joint project with MIC/NIA – KOREN
– one of its goals being IPv6 deployment since 1999
• Premium network separate from Kornet
– IPv6 over MPLS at PE of Premium network first and then full
IPv6 functions enabled over the premium network
– Part of access network/Kornet is not ready yet for IPv6 and
will take some time to be ready for IPv6
• International IPv6 testbed among PPM by international
team
• Small IPv6 testbed this year by Kornet/Premium team
• And my group – it used to be NGI division in the past
– Several IPv6 joint projects with NIA for wider IPv6
deployment and sustainable IPv6 services

My group’s IPv6 projects
• KTv6Net
– KT’s own IPv6 testbed in addition to KOREN
• KOREN
– IPv6 deployment, experiment, and operation/engineering
• IPv6-based WiBro trial services
– IPv4/IPv6 mobility, IPv6 web portal, 2 IPv6 Wi-Fi/WiBro networks
over 2 universities, tunnel servers
• IP-USN based meterological/oceanic observation system
– IP-USN(6LowPAN), Wireless Mesh Network
• IPv6-based administration system for city
– Kangneung City, several IPv6-based solutions(broadcasting, VoIP,
surveillance, etc)
• More projects planned for this year
– IPv6-based WMN infrastructure/applications with IP-USN over
cities aiming at u-City

KTv6Net
• The 1st KT’s own IPv6 testbed deployed
according to KOREN’s topology
• Will be used for many goals
– General IPv6, IPv6 IX, etc experiments
– IPv6 tunnel servers: hexago and openvpn
– Planning to launch trial tunneled IPv6 services
• Planning to connect IPv6 testbeds of
commercial IPS’s
– NTT, NTT West, etc

Summary/Conclusion – my 2 cents
• Government/IPv6 community pushing for
wider/complete IPv6 deployment
• But telco’s resisting real IPv6 deployment at
the moment
• Right answer: we as IPv6
engineers/researchers had better widen IPv6
deployment by ourselves to persuade telco’s
by using real IPv6 appications
• Thanks!
