[5] KOREAv6 Project

What is KOREAv6 Project?

To facilitate the commercialization and deployment of IPv6 services & equipments

Testing stability and interoperability of IPv6 equipments & solutions in IPv6 network

IPv6 Field Test

Providing IPv6 services for real users at home, campus, and a variety of areas

IPv6 Pilot Service

Achieving phased IPv6 Commercialization from 2005 through successful KOREAv6 Project

33/38

KOREAv6 Project

• Purposes
• Define barriers to deployment of IPv6 services in such areas in

home, office, campus, etc.

• Improve awareness of IPv6 service to the public
• Key contents
• Construct the national-wide IPv6 trial network
• Provide 10 trial services such as Eco System Monitoring, VoDv6,

VoIPv6, Internet gateway service, etc.

• Test the stability and interoperability of 39 equipments such as

routers, switches, VPN and so on

• Outcomes
• Retain operation skill of IPv4/IPv6 network with dual stack, NAT-PT
• Create a market of two-way services such as VoIPv6, Camerav6 etc.
• Enhance the functions of IPv6 equipments (KOREAv6 Logo has

been given to 35 IPv6 equipments)

34/38

KOREAv6 Project

• Phase I (2004) Done
• Construct the nation-wide IPv6 trial network
• Provide VoDv6, VoIPv6, IPv6 internet gateway service and
• Test 39 IPv6 equipment such as routers, switches, VPN etc.
• Phase II (2005) Now
• Applying IPv6 technologies to the 8 services of IT839 such as

WiBro, VoIP, and Home network

• Expanding IPv6 network to the public sector
• Transition of existing IPv4 portal sites and applications into IPv6

based ones

• Phase III (2006) Plan
• Providing large-scale All-IPv6 services to users as far as the 8

services of IT 839

• Supporting the commercialization of IPv6 WiBro contents and

applications

• Facilitating the massive use of IPv6 internet services in the public

sector
