3 KOREN Overview KOREN : KOREA Advanced REsearch Network
Non-profit research network Funded by Government [MIC] Established in 1995 NIA started its participation in KOREN from 2002 (NIA: National Information Society Agency) Support network service and R&D Project Currently, 79 R&D institutions 9 funded R&D Projects in 2007 NIA will manage KR’s International Networks (2008 ~) KR-JP APII Testbed TEIN2 KOREN means Korea Advanced Research Network. KOREN is non-profit research network funded by MIC. At first KT was in charge of KOREN from 1995. But after KT privatized in 2001, NIA took after the role of the Network. There was a transition period, but now NIA is fully in charge of KOREN. So if you want to contact with KOREN, please ask us at NIA.

But so many users connected to KOREN via KT facilities. So KOREN network is hybrid of KT and NIA facilities now. But, we will migrate the user connection from KT PoPs to NIA PoPs gradually. Eventually all the users will be connected to KOREN via NIA PoPs.

22 Remarks From 2008, NIA will manage both KOREN and APII/TEIN2 in Korea.
As before, KOREN hopes to keep continuing to use TransPAC2 through KR-JP APII link in order to connect with USA. Need to collaborate with US and JP researchers, and identify international research activities in application areas.

23 Thanks !
