7
Peering with other RE Networks

• 2001
• Peering with HPCNet/KREONet2 at 5 nodes
• Peering with KIX/NCA
• 2002
• Peering with KREN and PUBnet
• The whole RE community can use KOREN for
  research
• KOREN as backbone, others as PoP connected to
  KOREN

8
Peering with other RE Networks

• 2002
• A trial for a true regional RE network in
  Kwangju metropolitan city
• Community dark fiber
• Regional IX
• Regional sponsorship for collaboration higher and
  secondary education institutions

9
Peering with other RE Networks in AP Region

• 2001
• APII - APAN Tokyo XP 8Mbps
• APII - SingAREN 2Mbps
• APII - STAR TAP 45Mbps
• TEIN/Renater2 2Mbps
• 2002
• QGPOP 2 1GbE
• SingAREN ?
• TEIN/Renater2 20Mbps or more
• China ?

10
Peering with other RE Networks in AP Region

• 2002
• MIC plans to propose an Asia-wide RE network,
  APREN, which will build upon APII test beds
• TEIN is open to collaboration from other Asian
  countries

11
Peering with other RE Networks in AP Region

• 2002
• Korea-Kyushu Gigabit Network Project
• KJCN between Pusan and Fukuoka/Kitakyushu
• 2 1GbE links between KOREN Pusan node and
  Kyushu Gigapop(QGPOP)
• Hope this can be extended into China from Seoul
• An initiative by APAN-KR in KR and
  QGPOP/ISIT/APAN-JP in JP
• First and great model for Asia

12
Cross-Pacific Connectivity

• 2001
• STAR TAP 45Mbps
• 2002
• STAR TAP 45Mbps
• Via Kyushu-Korea Gigabit Network
• KOREN - QGPOP - Tokyo XP - StarLight

13
International Science Collaboration
