[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
33/27
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)
34/27
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, VoI
P, and Home network Expanding IPv6 network to the public sector Transition of existing IPv4 portal sites and applications into IPv6 based on
es 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
