▣ Efforts◈ Regular – ETRI(MIC), OPICOM, i2soft and SKTelecom◈ Informal - KWU, SSU, KAIST, SNU, HNU, CWU, etc.
▣ R&D activities◈ IPv4/IPv6 Translator (6TALK – ipv6 TrAnsLator of Krv6)◈ BIA & DSTM Extensions (contributing to IETF NGTrans) ◈ QoS, Multicast(Xcast), Mobility◈ Auto-Configuration Networking (contributing to IETF Zeroconf)
▣ Period ◈ 1st Phase : 2000~2001 ◈ 2nd Phase : 2002 (will be re-scheduled)

ConclusionConclusion
▣ New challenges for Next Generation Internet in Korea◈ More than 20 million users of Internet (50% of population)◈ Emerging Internet areas
IMT-2000Home NetworkEtc.
▣ IPv6 will be core technology for next-generation Internet.
▣ It is not too early to begin planning for IPv6 use in your country.
▣ Korea will contribute to the deployment of IPv6 in the Asia-Pacific region, as well as worldwide.
