  1. HEP Research & Network Service in Taiwan APAN-TW Secretariat Dr. Simon C. Lin APAN-TW NOC Mr. Wenshui Chen 2003-1-20

  2. Outline • HEP group in Taiwan and collaboration joined • Highlights • Network Activities • Requirements • APAN-TW Network Service for HEP projects • Issues

  3. HEP group in Taiwan and collaboration joined • Academia Sinica: Join Fermilab CDF Collaboration in 1993. • National Central University: L3 at CERN (1990) • National Taiwan University: Belle at KEK (1995)

  4. HEP group in Taiwan and collaboration joined (cont.) • All three groups join the LHC at CERN. • LHC is next generation high energy particle collider. • AS: ATLAS(A Toroidal LHC ApparatuS ) • NCU and NTU.: CMS

  5. CDF • CDF: The Collider Detector at Fermilab • More than 500 physicists work on the collaboration • The discovery of the top quark was one of the major results of the CDF collaboration.

  6. CDF (cont.) • Installation of Silicon Detector into the CDF Detector

  7. Highlights • CDF: • Top quake discovery in 1995. Taiwan is one of the 5 countries in CDF. • Evident of CP violation in B sector (1997) (Sin(2beta) measurement) • Belle: • CP Violation in B Physics(2002). • L3: • Higgs Search: Find one Higgs candidate (2000)

  8. Network Activities • The major network activities for an HEP experiment include • Get data set from KEK: FTP, sftp • Run experiment on remote server: Telnet, ssh • Multipoint Video Conference • VRVS • H.323/H.320 conferencing facility, MCU (Multipoint Control Unit)

  9. Requirements • Sufficient bandwidth for Transferring data set with size of 2 ~ 20 GBytes for multiple researchers at the same. • Sufficient bandwidth and efficient management to support stable multipoint video conferencing • Within 2 ~ 3 years, the network should be able to support Tera Byte data file transferring bi-directionally, not including GRID requirement.

  10. Expected Network Performance Unacceptalbe Good

  11. APAN-TW Network Service for HEP projects • International network Connection • Video Conference Facilities • H.320: PictureTel • H.323:Polycom VS4000 • MCU: Polycom MGC500; capable to support 24 concurrent sessions • QoS

  12. ASIA regional Network Development • 1999-5 TW-KEK 256kbps IPLC for HEP projects • 2001-1 TW-KEK IPLC upgrade to 1.54Mbps • 2002-2 TW-APAN IPLC 155Mbps • 2003-2 TW-StarLight STM4 link

  13. APAN-TW Network Infrastructure 2003 • TW-USA: 622Mbps(2002-11) • TANet: 440Mbps for Internet-1 • Another 3 STM1s under negotiation • TANet2: 180Mbps • GE to PNW-gigapop for Abilene • T3 to Chicago for STARTAP • TW-StarLight: STM4(2003-2) • TW-London: STM1 (2003-2) • TW-APAN: STM1(2002-2) • TW-HARNet: STM1(2002-2)

  14. APAN-TW ASIA Research Network Connectivity(Jan,’03)

  15. APAN-TW Network Infrastructure Future Plan • TW-APAN: STM4 • TW-StarLight: STM16 (for GRID application) • TW-SouthEastASIA: STM1

  16. Issues • Packet delivering via the most effective path • Stable Quality of Videoconference: QoS • Data Transferring Correctness • Future Network Plan must be able to support GRID
