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

2. 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. 3 Logical Topology of TANet Giga MAN NCU (RNC) NCHU (RNC) CCU (RNC) NCKU (RNC) NSYSU (RNC) Taipei GigaPoP (MOECC/ASCC TP City/County Schools) NCHC NTHU NCCU (RNC) NHNC (RNC) KH County Schools KH City Schools NTU (RNC) NDHU (RNC) Layer2 Backbone (40 Gbps or higher) NDNC (RNC) Layer2 Net 3G 1G 3G 4G 1G 5G 1G Layer2 Net NCTU (RNC) 3G

4. 4 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

5. 5 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

6. 6 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

10. 10 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

11. 11 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

12. 12 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

13. 13 IPv6 – Digital Content for User Themes History, Politics, Humanities, Archeology, Ethnology, Diplomacy, Zoology, Botany, Species, Genomics, Linguistics, Geology, Geography, Visual Arts, Performing Arts, etc. Data Type Rubbings, Files, Official Documents, Antiques, Rare Books, Full Text, Specimens, Corpus, Maps, Photos, Painting and Calligraphy, Video Tapes, Score, Dress, Reports, Investigation, etc. Organization Academia Historica, National Library, National History Museum, National Museum of Natural Sciences, National Taiwan University, Taipei National University of The Arts, National Palace Museum, Academia Sinica, etc.

14. 14 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

15. 15 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?
