summary of my presentation at the previous workshop held at rio in feb 2004
Summary of my presentation at the previous workshop held at Rio in Feb 2004
  • In Japan, SuperSINET connects most of major universities and national laboratories and provides them of 10Gbps IP connection, discipline-dedicated inter-site GigE’s, MPLS-VPN’s, and 10Gbps bandwidth to Abilene, ESnet, and Geant, and is indispensable for HEP and other e-Sciences. However universities (especially private universities) that are not SuperSINET nodes are facing Digital Divide.
  • In Asia, APAN is providing, or is expected to provide, the networks necessary for HEP and other e-Sciences. Its bandwidth in east Asia is, or is becoming, ~Gbps. However the bandwidth in the other areas are very low (<~Mbps), which is producing Digital Divide.

Domestic connectivity for HEP in Japan
    • Had own links before, still have some, but depend on NII mainly
    • SuperSINET
      • I believe SuperSINET is one of the most advanced networks
      • Upgrade is being planned
    • SINET
    • Non-SINET
  • International connectivity for HEP
    • America/Europe
      • Had own link before, but depend on NII now
    • Asia
      • Had own links before, still have one, but depend on APAN mainly
      • Becoming Gbps in east Asia, but still poor in other areas

SuperSINET’s links to America and Europe
  • NII locates and operates a router at New York for SuperSINET’s peering with R&E networks in America and Europe.
  • New York is the only place where SuperSINET can peer with all of Abilene, ESnet, and Geant.
  • SuperSINET’s link to New York has been 10Gbps and has been connected to MAN LAN with 10GE since December 2003.
slide15
America/Europe
    • NII’s 10Gbps link to New York
      • OC192 from Tokyo to a router at New York
      • 10GE connection from the router to MANLAN
      • Abilene and ESnet are already there with 10GE
      • Geant is expected to come there with 10GE
        • Currently, Geant is connected to the router with OC48
    • NII’s 2.5Gbps link to Los Angels
      • OC48 from Tokyo to Los Angels since this April
      • Can provide shorter RTT but smaller bandwidth
      • Peering there includes CalREN which includes SLAC
        • Caused a trouble for the BINP-SLAC traffic

    • The network is essential for the HEP collaboration, and we needed to have it by ourselves.
  • The cost for each half-circuit was/is paid by each end.
    • KEK-IHEP (Beijing, China)
      • Since 1994 Until 2003
    • KEK-BINP (Novosibirsk, Russia)

An on-going HEP experiment at KEK, Japan

slide23
China
    • Japan (APAN-JP) is connected to Gloriad HK node with OC48 since this January.
    • Gloriad HK and Beijing is connected with OC48.
    • Thus, there is 2.5Gbps for China-Japan traffic.
slide24
Taiwan
    • APAN-Taiwan has a router at Tokyo, which is connected to Taiwan at 622Mbps.
    • APAN-JP router peers with APAN-Taiwan router with GigE.
    • KEK is preparing to peer with APAN-Taiwan router directly with GigE.
slide25
Russia
    • KEK’s 512Kbps link to BINP
      • Established for the Russia-Japan HEP traffic.
      • Provides transit for the Russia-ESnet traffic.
        • In order to exclude the foreign traffic, an IP tunnel connecting ESnet and KEK is used.
      • Upgrade to 2Mbps?
    • Gloriad
      • Is expected to be available for Russia-Japan and Russia-ESnet HEP traffic, and to replace the KEK-BINP link.
slide26
Korea
    • G/H (Genkai-Hyeonhae) started to operate in early 2003.
    • SuperSINET peers with KOREN with GigE, independently from APANJP-KOREN peering.
    • So there is 1Gbps between KOREN and SuperSINET.
access to belle s data from internet what happened there
Access to Belle’s data from Internet- What happened there-
  • High-bandwidth access from SuperSINET to Belle Internal LAN is easy.
  • There was no need for high-speed access to Belle data from Internet but SuperSINET, before.
    • Belle group’s poor Firewall from Internet was sufficient enough.
  • High-speed connection from Korea established in 2003 was the first case of the high-speed access from Internet.
  • The environment was reorganized last year. There should be no problem any more for the access at ~Gbps!?
  • The further reorganization will be made in March 2006, when 10Gbps access to the Belle data server will become possible.
