  1. AP Network Report Aries Hung, Min Tsai ASGC WLCG T2 Asia Workshop TIRF, Dec 2, 2006

  2. Site network validation

  3. T0-T1-T2 network connectivity

  4. Australia • Australia-UNIMELB-LCG2： • RTT: 137 ms – 340 via US • July 2006, establish peering with AARNet at Singapore. • Alter routing path • from ASNet-TW ASNet-US  AARNet  Australia-UNIMELB-LCG2 • to ASNet-TW  ASNet-SG  AARNet  Australia-UNIMELB-LCG2

  5. China • BEIJING-LCG2 • RTT: 55 ms • BEIJING-CNIC-LCG2-IA64 • RTT: 55 ms

  6. India

  7. India • IN-DAE-VECC-01: • 320 ms • Routing path: • ASNet-TW  ASNet-HK  Flag  RIL-IDC  ERNet-IN  INDAE-VECC-01 • INDAE-VECC-01  ERNet-IN  Geant2  Internet2  TWAREN  ASNet-TW • INDIACMS-TIFR: • 280 ms • Routing path: • ASNet-TW  ASNet-HK  Flag  RIL-IDC  ERNet-IN  INDAE-VECC-01 • INDAE-VECC-01  ERNet-IN  Geant2  Internet2  TWAREN  ASNet-TW • Issues • Could ERNet-IN prefer AS route from RIL-IDC and Flag?

  8. Japan • JP-KEK-CRC-01: • RTT: 62 ms • JP-KEK-CRC-02: • RTT: 64 ms • TOKYO-LCG2: • RTT: 61 ms Workday Holiday

  9. Korea Workday Holiday • LCG_KNU: • RTT: 84 ms • Sep. 2006, alter route path of SE endpoint network segment (go through HK), RTT: 58 ms now. • Could 155.230.0.0/16 go through HK?

  10. Pakistan

  11. Pakistan • NCP-LCG2: • 240 ms • Nov. 2006, alter route path • from ASNet-TW  ASNet-US  AT&T  UUNet  ITIKarachi  NTCPKNet  NCP-LCG2 • to ASNet-TW  ASNet-HK  ANC  SingTel  NTCPKNet  NCP-LCG2 • PAKGRID-LCG2: • 348~387 ms • many icmp checksum error (firewall restriction?) • Could NTCPKNet advertise route info to SingTel?

  12. Singapore • GOG-Singapore: • RTT: 49 ms • July 2006, alter routing path • from ASNet-TW  ASNet-HK  ANC-HK  ANC-SG  GOG-SingAREN • to ASNet-TW  ASNet-SG  SingAREN  ANC  GOG-SingAREN

  13. Taiwan

  14. Taiwan-IPAS-LCG2: < 1 ms TW-FTT: < 1 ms TW-NIU-EECS-01: 9 ms Taiwan-NCUCC-LCG2: 17 ms TW-NCUHEP: 11 ms TW-NTCU-HPC-01: 5 ms TW-THU-HPC: 5 ms Taiwan domestic Daytime

  15. Network monitoring • Monitoring tools • Smokeping -- latency measurement tool • Nagios -- host, service and network monitoring program • MRTG • WeatherMap • Evaluation • PerfSonar: http://www.perfsonar.net/ • IEPM: http://www-iepm.slac.stanford.edu/

  16. Other issues • Info collection • Contact info of site network manager • Contact info of circuit provider (optional) • Network map, include bandwidth (WAN & LAN) • Firewall rules • Open ICMP access to ASGC (140.109.98.0/24 and 202.169.168.0/22) • If possible, enable iPerf daemon on one server for testing

  17. ASGC future plan • T0-T1 connectivity: • Upgrade to 10Gb (2007 Q2) • T1-T2 connectivity: • TW-JP: Upgrade to 2.5+Gb • TW-HK: Upgrade to 2.5+Gb • TW-SG: Upgrade to 622+Mb

  18. Taiwan Juniper M160, Juniper M320 Located in Academia Sinica HongKong Juniper M20 Located in Mega-iAdvantage Building (in Chai-wan area) Japan Juniper M20 Located in KDDI Building (same as APAN building, in Otemachi-Ku area) Singapore Juniper M7 Located in SingAREN GIX Building America Juniper T320, located in Palo Alto PAIX Building Juniper M40e, located in StarLight Netherlands Juniper M20 Located in SARA ASNet POPs
