  1. APAN-TaiwanStatus Report Yu-lin Chang, ylchang@ascc.net APAN-TW NOC @ APAN 2003 Academia Sinica Computing Centre, Taiwan

  2. Three Major R&E Networks • TANet • The first and largest high speed IP network in Taiwan • Every schools, colleges, universities, and research institutes are connect to TANet • Highly coverage of connections to domestic ISPs. • Limited bandwidth of Internet connection to U.S. • Held and Operated by MOECC (Computer Center of Ministry of Education) • Now, TANet is already moved to the new Gigabit Ethernet MAN structure (“TANet Giga MAN”, based on the experience of Taipei GigaPoP)

  3. Three Major R&E Networks (cont.) • TANet-2 • Provide reserved bandwidth between major universities and research institutes • Connect to U.S.A. for Internet-2 traffics • Initiated by ASCC 1997, operated by NCHC • Physical circuits will merged back to TANet in Q2, 2003 • NCHC will build the next generation backbone for R&E users called “TWAREN” • Note: ASCC = Academia Sinica Computing Centre NCHC = National Center of High-performance Computing

  4. Three Major R&E Networks (cont.) • ASNet (APAN-TW) • Operated by Academia Sinica Computing Centre • Initiate International T3 Project to connect Taiwan R&E Network to the U.S.A. • Build up the “Taipei GigaPoP” infrastructure to promote and provide IP over dark fiber service for research and educational network since 1997 • Provide “Research Network Connectivity” since 1997. To provide high bandwidth and managed connection service between Taiwan and Japan; Hong Kong; StarLight; Europe • “Biomedical and Scientific High Speed Network” to provide /4 or  interconnection between some universities for specific research projects

  5. Carrier Class Spec in ASCC • Environment • 24x7 Operators standby • Air Conditioning, UPS, Power Generators • Fire detection and suppressing system • High Speed, Low Latency Connections • Fast Ethernet, Gigabit Ethernet, 10GE • OC-3, OC-12, OC-48, OC-192 • Multiple Fiber-Ring Providers • Taipei GigaPoP, CHT, TFN, EBT, KBT, Sparq

  6. APAN-TW Connectivity (Dec,2002)

  7. Biomedical & Scientific High Speed Network

  8. Major services • Circuit Status Monitoring • MRTG based semi-real time throughput monitoring • Daily, weekly, and monthly traffic volume statistics reports • Self-developed IDS based on flow analysis technique • Large Scale Video Conference Service • H.320 and H.323 conference system • Conference scheduling and controlling • 24 or more conferences can be holed at the same time • Autonomic scheduler is under developing by ASCC software team • Free of charge for R&E user groups • ADSL subscription service • Cooperated with CHT and TFN to cover the entire Taiwan inland • Provide ADSL subscription to fellows and connectors’ fellows • IPv6 is a new service that we strongly promote

  9. IPv6 – Deployment • Address space delegation • 6Bone pTLA: 3FFE:4001::/32 • APNIC sTLA : 2001:0C08::/32 • IPv6 connections • Over 15 native connected networks • Over 20 tunnel mode networks • 320Mbps for pure IPv6 networks • 120Mbps domestic bandwidth • 100Mbps to APAN-TokyoXP • 100Mbps to NSPIXP-6

  10. IPv6 – Operations • Looking glass • Helps to check the prefix advertisement • Tunnel broker • Helps to setup IPv6 over IPv4 tunnel • 6to4 relay • Provide automatically mechanism to relaying packets without artificial helping • AS-path tree viewer • Helps to recognize the network topology

  11. IPv6 – Digital Content for User

  12. International Project Supporting • CDF Run II Production Farm (TW, U.S., Slovak) • Collider Detector at Fermilab (CDF) • APAN-TW NOC supports USD 700K/year • http://alloc.apan.net/status/cdfr2.html • IRCache; National Cache Network (TW, U.S.) • APAN-TW NOC supports USD 100K/year • http://alloc.apan.net/status/ircache.html • ISEE Project (TW, U.S.) • Internet-based Simulations on Earthquake Engineering • APAN-TW NOC supports USD 200K/year • http://alloc.apan.net/status/isee.html

  13. Challenge of Operation • Fiber-Rings • ROW for public conduit • Unexpected fiber-cuts • Inter-connections of multiple Fiber-Rings • Facilities • Version control of operation systems • Feature-sets selection • Should we use the beta code or non-wildly deployed OS to provide new feature?
