KORENKorea Advanced Research Network

• KOREN/APII/APAN-KR NOC
• Operated/Engineered by NGI Division, KT TNL
• jhlee_at_noc.koren21.net
• Fukuoka, Aug. 31, 2001

MICs 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

MICs 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)

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

Network Features

• Full ATM intrastructure except for GE link to
  KAIST
• All members have a 155Mbps link
• 3 internatl 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 CBWFQs
• Can guarantee backbone bandwidth for a project or
  important traffic

13
IPv6

• 2001220/35 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/internatl parties
• http//www.kr.apan.net/

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 youre 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 - MICs points

• Please come and join us
• KOREN is open to all research community
• We know the importance of this network and
  projects
• Well 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
