Three Networks Servicing R&E Communities in Taiwan

Three networks in Taiwan provide network services for the R&E communities

TANet, funded by the Minitry of Education, leases bandwidth from commodity vendors. It services higher education and K-12.

TANet2, funded by the National Science Council, is operated by the NCHC

ASNet, gets funding largely from the NSC, is managed by the Academia Sinica

The circuit acquisition is thus sometimes a tripartite effort, done jointly

33

TANet2 and TWAREN TANet2 is a national research network. It has be

en in operation since 1998 to service R&D TWAREN is the next version of TANet2, re-desig

ned with three levels of services –production, research and optical networks. TWAREN (TaiWan Advanced Research & Eduction Network)

The production network of TWAREN has just begun operation. Its research network and optical network are being implemented.

The two networks share the same circuits for international connectivity. Both managed by the NCHC.

Trans-Pacific link to Seattle is at STM-16 Link from Seattle to STARLight was upgraded to STM-4.

An additional 1GbE lightpath from CANARIE serves as TaiwanLight

To date, connections to Asia and Europe are largely made by ASNet. Joint leasing by the three networks will be common in the future

Connections to Asia APAN Tokyo-XP: 155 622 Mbps (Feb, ‘04) Hong Kong: 155 Mbps Singapore: 155 Mbps (activated 2. 20.2004)

AMSIX (Amsterdam, activated in April 2004). The 155 Mbps link to UK will be terminated in Mar

Meshes in with APAN Infrastructure

Taiwan is a well-connected APAN member Meshes well in the APAN infrastructure fabr

ic For other R&E networks in Asia Pacific regi

on, Taiwan is very well-suited as an access point for peering and transit; and its multiple links as backup routes for other links.

Asian-Pacific PoPs Links to HK and Sg make TW, HK and SG e

quivalent PoPs which may serve as access points for other APAN networks
