  1. TW LCG Network Status Update Yu-lin Chang Academia Sinica, 2005/04/08

  2. SC test bed @ Taipei

  3. Taipei Status • ASNet* runs one STM16 IPLC from Taipei to Amsterdam • One GE Local loop from Amsterdam to Geneva (via NetherLight LightPath Service), second GE is waiting to turn on (I already signed the xconnect order form) • will double the IPLC on July 1st (contract will be signed on May 27th) • ASCC LCG facilities now have multiple GE uplinks to ASNet’s core router; will be replaced by one or two 10GE during this summer vacation • ASNet connects (10GE*2 + STM64*n) to domestic backbone, a.k.a. TANet/TWAREN joint backbone, to reach T2’s in Taiwan. • Every T2 in Taiwan has it’s own 10GE link to the domestic backbone * ASNet (Academic Services Network, as#9264) is the network division and is also the network name that registered in APNIC.

  4. Asia Pacific Link Status • How many T2s in Asia Pacific region? • Taipei – Tokyo • STM-4 IPLC • 2*GE to APAN-JP (for JP Universities) • Will have GE to SiNet/SuperSiNet (for KEK) • IPLC should be increased before LCG production run. • Taipei – Singapore • STM-1 IPLC to SingAREN (National Grid Office of Singapore)

  5. Asia Pacific Link Status • Taipei – Hong Kong • STM-4 IPLC, will upgrade to STM-16 on Feb 1st, 2006 (contract already been signed on March 30th) • GE link to CERnet, GE link to CSTnet • CERnet : China Education and Research network • CSTnet : China Science and Technology network • Maybe have GE link with KOREN (still work with KOREN engineer)

  6. Technical Issues • LightPath • How urgent is it for the lightpath between T1 and T2 ? • Today, there is no lambda can be brought in AP region (there is only SDH circuits) because of the design of cable systems • Can MPLS L2 VPN and/or premium IP services provide same (or almost the same) quality compares to LighPath in the LCG environment ? • Even though, ASNet is still surveying the WDM equipments

  7. Technical / Financial Issues • Taipei to other T1s • Interconnections • Via GEANT2 and Abilene ? Or dedicated links ? • Performance ? • Taipei to AP region T2s • Cost sharing module should be setup ASAP.
