[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
