  1. KORENKorea Advanced Research Network KOREN/APII/APAN-KR NOC Operated/Engineered by NGI Division, KT TNL jhlee@noc.koren21.net Fukuoka, Aug. 31, 2001

  2. MIC’s Project - KOREN • To help develop information super-highway infrastructure technologies • To help develop applications requiring information superhighway infrastruc. • To help with research and education activities more generously • To make come true information society • Jointly funded by MIC/KT since 1995

  3. Fund by MIC/KT - KOREN • 1995-1997 • 89/MIC + 146/KT = 235/Total • 1998-2000 • 193/MIC + 111/KT = 304/Total • 2001-2005 • 530/MIC + 277/KT = 807/Total • Unit is 100 million won.

  4. MIC’s Plan for Information Superhighway • 3 target networks • KII-G : Public national network • KOREN : Research networks backbone • Commercial IP networks by domestic carriers • Fund • 1995-1997 : 29,779(5,324/MIC) • 1998-2000 : 76,246(6,679/MIC) • 2001-2005 : 219,726(24,653/MIC) • Unit is 100 million won.

  5. Brief History - KOREN • 1st stage 1995 - 1998 • ATM network for testing ATM equip/appl • Very limited IP services • 2nd stage 1999 - 2001 • KT NGI Division took over KOREN NOC • Transformed it into a 5-node IP network • Formed a tight networking with HPCNet • Established jointly with KREONet2/HPCNet a STAR TAP connection • 3rd stage 2002 – 2005

  6. Members - KOREN • 32 special members : current members • Should pay an annual fee • Optical cables to them provided by MIC/KT • Additional general members • Should pay for its access link to our node • but not annual fee • All HPCNet/KREONet members can be considered our members... • More than 250 members

  7. KOREN is - my definition • Advanced research/education network with both higher bandwidth/advanced networking technologies as platform • Network which allows research- and education-related traffic to flow freely among members in addition to project-related traffic, but not commodity traffic • Production network, not a testbed • Collaboration is the first priority

  8. Kwangju Taejon Taegu Pusan Seoul TEN-155 HPCnet HPCnet SingAREN HPCnet HPCnet HPCnet Domestic Public/Commercial Networks Global Research Networks 622 Mbps 155 Mbps Network Overview APAN Tokyo XP KIX APAN-KR Seoul XP STAR TAP Other symbols borrowed from CA*net3

  9. Network Features • Full ATM intrastructure except for GE link to KAIST • All members have a 155Mbps link • 3 internat’l APII links - US/JP/SG • New networking technologies • IPv4 with MPLS/QoS/native multicast • Native IPv6

  10. IPv4 • BGP-Peering is the priority • A limited address space, 8 C-classes • AUP • Policy-based routing • Transparent caching enabled

  11. Multicast • PIM-SM/MBGP/MSDP is the ground • Anycast-RP • No AUP with mulciast traffic, so • Can provide DVMRP Tunnels for Mbone-Korea and others • Pushing multicast onto the desk is the priority

  12. Differentiated Services • DS-enabled JP-KR link : 2 CBWFQ’s • Can guarantee backbone bandwidth for a project or important traffic

  13. IPv6 • 2001:220::/35 for our members • Our network is a native IPv6 network with connections to 6TAP/WIDE/... • No AUP with IPv6 • Pushing IPv6 onto the desk is the priority • All koren Web pages can be accessed using IPv6

  14. Research - APAN-KR WGs • Measurement, Digital Video • QoS, MPLS • Storage and Cache • IPv6 • Active/voluntary collaboration among domestic/internat’l parties • http://www.kr.apan.net/

  15. Become a Member? • Apply for KOREN membership • If desginated as special member • you pay annual fee and a direct access link will be given without charge • Otherwise you’re a general member • you pay for access link, not annual fee • MIC covers half or 35% of your link cost • http://www.koren21.net

  16. NOC Missions • Opeate/sustain KOREN, 24x7x365 • Provide services • Support members • Engineer with new technologies • http://noc.kr.apan.net

  17. Remember These - my points • Production network for application development • Is not a network on which your own work is tested • Is not a network only for network techies • Open collaboration among members is the most important thing

  18. Remember These - MIC’s points • Please come and join us • KOREN is open to all research community • We know the importance of this network and projects • We’ll cover some of your costs to become a member...

  19. Future Plan - KOREN • Starting 2002, KOREN will evolve to an IP network with WDM technology • So the Genkai project is well fit to our plan

  20. The End
