APAN-TW NOC @ APAN 2003
Academia Sinica Computing Centre, Taiwan
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)
2
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

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

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
10
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
11
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
12
IPv6 – Digital Content for User
Themes
History, Politics, Humanities, Archeology, Ethnology,
Diplomacy, Zoology, Botany, Species, Genomics,
Linguistics, Geology, Geography, Visual Arts,
Performing Arts, etc.

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?
