  1. CHEP2000 conference • at Padova on 9 February 2000 • Yukio.Karita@kek.jp • Networking in Asia

  2. International Connectivity as of June 1997

  3. Host Count as of July 1999Source: Internet Software Consortium (http://www.isc.org/) TOTAL 56,218,330 JP 2,072,529 AU 907,637 TW 424,209 KR 260,146 NZ 182,021 SG 103,862 HK 98,183 CN 62,935 MY 53,447 TH 27,690 IN 17,979 ID 15,766 PH 9,942 PK 3,027 LK 983 : :

  4. Outline I’d like to focus on the networking for the intra-regional connectivity within Asia(-Pacific) region available for the HENP collaboration, but before going into it I’ll talk on the inter-regional connectivity first. • Inter-regional connectivity • general A&R • HENP dedicated • Intra-regional connectivity • HENP dedicated • APAN • Summary

  5. Inter-regional connectivity between Asia(-Pacific) region and the other regions

  6. Three ways to get the connectivity to outside the region • Hub model • A region has a hub through which each national A&R network gets the outside connectivity. The hub has big line(s) to the other regions. • Parallel model • Each national A&R network in a region has its own line(s) to the other regions. • Hybrid model • Some national A&R networks have their own lines, while the others depend on a hub.

  7. Asia is in Hybrid model. • Similar to Europe, where many countries have their own lines to US, many countries in Asia(-Pacific) have also their own lines to US.

  8. General A&R lines to US • JP-US NACSIS ~300Mbps IMnet-HPIIS ~100Mbps • AU-US AARnet ~60Mbps • KR-US KREN ~45Mbps KREOnet ~6Mbps • TW-US TAnet ~45Mbps • SG-US SingaREN ~14Mbps • HK-US ~12Mbps • CN-US CSTnet ~10Mbps CERnet ~3Mbps • TH-US CAT ~8Mbps NECTEC ~2Mbps

  9. NACSIS US/EU line as of today Abilene ESnet Router CERN Router LBNL CERN STAR TAP ESnet Router 30Mbps Chicago 10Mbps 4Mbps TEN155’s MBS HEPnet-J Router 300Mbps 30Mbps 15Mbps San Jose NewYork London KEK NACSIS 270Mbps Tokyo Kyoto 10Mbps Teleglobe.Net TEN155’s IP Service Default Internet Frankfurt : ATM switch

  10. Inter-regional bandwidths dedicated to HENP ATM-PVC’s configured in the NACSIS US/EU line • ~10Mbps for KEK’s peering with ESnet at STARTAP • ~10Mbps for KEK’s peering with ESnet at San Jose • -waiting for an LBNL-SanJose circuit (a T3 circuit) • ~5Mbps for KEK’s peering with CERN • -CERN-London is configured in TEN-155’s MBS • (~5Mbps for KEK’s peering with DESY) These are guaranteed bandwidths configured in the general A&R networks.

  11. inter-regional ATM PVC’s dedicated to HENP existing today CERN ~5Mbps KEK ESnet ~10Mbps

  12. NACSIS’s upgrade • NACSIS’s lines are upgraded once per year. • Domestic lines: every April • The biggest backbone will be 405Mbps in April 2000. • International lines: every October • NACSIS’s future prospect • Aggregated bandwidth to US/EU will be doubled every year: 50Mbps(1997), 150Mbps(1998), 300Mbps(1999), 600Mbps(2000), 1.2Gbps(2001), 2.5Gbps(2002), 5Gbps(2003), 10Gbps(2004), 20Gbps(2005), …

  13. Intra-regional connectivity in Asia(-Pacific) region (international connectivity within the region)

  14. As the inter-regional bandwidths for HENP are becoming rather big, the intra-regional connectivity for HENP is becoming more and more important, especially in Asia.

  15. Intra-regional lines dedicated to HENP • KEK-IHEP (Beijing, China) • KEK-BINP (Novosibirsk, Russia) • KEK-AcademiaSinica (Taipei, Taiwan)

  16. KEK-IHEP link history • till July 1994, KEK-IHEP traffic was routed via SLAC-IHEP satellite circuit. • in July 1994, KEK-IHEP 64Kbps line was created. • began as a satellite circuit temporarily and replaced by a fiber circuit in April 1995 • SLAC-IHEP link was taken over by this line • upgraded to 128Kbps in October 1998. • another upgrade is being studied. • routing • default route for all the outside connection from IHEP

  17. KEK-BINP link history • till March 1998, KEK-BINP traffic was routed via DESY-BINP satellite circuit • in March 1998, KEK-BINP 128Kbps line, a fiber circuit (partly microwave), was created. • in September 1999, Moscow area (ITEP, MSU, …) was connected with KEK via BINP. • upgrade of the line is being studied. • routing • BINP-ESnet, MSU/ITEP-KEK/HEPnet-J

  18. KEK-AcademiaSinica link history • till January 1999, KEK-Taiwan traffic was routed via US. • in January 1999, KEK-AcademiaSinica 128Kbps line was created. • upgrade of the line to a FrameRelay circuit (1.5Mbps port, 512Kbps CIR) is being prepared. • routing • TAnet-AcademiaSinica-KEK-SINET-IMnet

  19. APAN • Asia Pacific Advanced Network Consortium • http://www.apan.net • started in June 1997 • KEK will be directly connected with IMnet/APAN on 1 March 2000.

  21. APII Asia Pacific Information Infrastructure, a project initiated by APEC • http://www.crl.go.jp/t/team1/APII • AI3 Asian Internet Interconnection Initiative • http://www.ai3.wide.ad.jp

  22. Countries in Asia(-Pacific) requiring connectivity for the HENP collaboration • JP, KR, CN, TW, PH, SG, IN, ID, VN, TH, RU, MY, AU • HENP lines • KEK to CN, RU, TW • APAN lines • APAN_Tokyo to KR, PH, TH, SG, AU (now) to VN, MY, ID (coming)

  23. APAN looks very useful for getting the intra-regional connectivity for HENP. • APAN is not automatically open to all the A&R community. It is per project base. Each project wishing to use the APAN needs to be approved by its committee in advance. • A project application was submitted with the project name “ACFA network” in January 2000. • It is being approved by the APAN committee.

  24. IP multicast with satellite • Satellite and data broadcasting might be interesting especially in Asia. • Using IP multicasting with usual TV antennas and TV tuners for receiving data can be very interesting. It can be cheap and can be used everywhere in Asia. • Data transfer rate is ~30Mbps with usual TV antennas, and can be ~1Gbps with expensive earth stations.

  25. ACFA-NWG • Members from China, Korea, India, Thailand, and Japan

  26. Summary • Compared with the inter-regional connectivity for HENP which is becoming bigger and bigger, the intra-regional connectivity in Asia(-Pacific) still remains poor. • We are trying to improve it • by utilizing APAN and • by upgrading the HENP dedicated lines.
