IPv6 Deployment Status in KT/Korea
Jan. 23, 2007, IPv6TF, APAN ManilaLee, Jaehwa, jhlee@koren21.netKT Future Technology Laboratory
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 applicat
ions projects thru NIA– Depending upon only telco’s for IPv6 deployme
nt over their commercial networks• Now (since 2005)
– Interested in real IPv6 applications, contents, and users
– Formed IPv6 Deployment Promotion Council this year
MIC/NIA’s KOREAv6 Project
• Goal– increasing the recognition of IPv6, expanding t
he IPv6 network and activating the IPv6 service
• Many subprojects– VoIP, WiBro, Home network, hdtv, medical, etc
• http://koreav6.vsix.net– Not much English introduction
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
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
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 ta
ke some time to be ready for IPv6• International IPv6 testbed among PPM by international te
am• 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
KT – Premium network
• 1st phase by 2010

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 aimi
ng 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
KTv6Net
KOREN
• KOREN– IPv6 deployment, experiment, and
operation– JP-KR link upgraded to 10G– Plan to upgrade to 20-10G this year
KOREN
• Current situation– 6 nodes: SL, DJ, DG, BS, GJ, SW– L2 capacity: 2.5G ~ 40Gbps– Access links: 155Mbps ~1Gbps– members
• Over 50 members composed of universities and research institutions
• International peerings– APII (Asia Pacific Information Infrastructure)
• JP-KR: 10Gbps x 2 개• CN-KR: 155Mbps
– TEIN2 (TransEurasia Information Network)• SG/EU-KR: 622Mbps

IPv6-based WiBro Trial Services
• IPv6 mobility– Several solutions as well as for IPv4– Standard/non-standard solutions
• IPv6 web portal – ipv6.paran.com– KTH IPv6 portal, we secured 50K subscribers last year
• 2 real IPv6 Wi-Fi/WiBro networks– 2 universities: KAIST and DSU connected to KOREN
• tunnel services– Hexago solution– OpenVPN

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!
