MIC’s Project - KOREN
To help develop information superhighway 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
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
 Unit
+ 277/KT = 807/Total
is 100 million won.
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.
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
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
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 projectrelated 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 internat’l APII links - US/JP/SG
 New networking technologies
 IPv4
with MPLS/QoS/native multicast
 Native IPv6
IPv4
 BGP-Peering
is the priority
 A limited address space, 8 C-classes
 AUP
 Policy-based routing
 Transparent caching enabled
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
Differentiated Services
JP-KR link : 2 CBWFQ’s
 Can guarantee backbone bandwidth
for a project or important traffic
 DS-enabled
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
Research - APAN-KR WGs
Measurement, Digital Video
 QoS, MPLS
 Storage and Cache
 IPv6
 Active/voluntary collaboration among
domestic/internat’l parties

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

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