1 TWAREN Optical Networking on TANet2 and TWAREN Ray-Ming Hsu National Center for High-performance Computing Hsinchu Science Park, Taiwan February
2 TWAREN TANet2 and TWAREN TANet2 is a national research network, in operation since 1998 to serve researchers in academia and research centers. TWAREN is the next version of TANet2, re- designed 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.

12 TWAREN StarLight StarTap CA*Net4 Abilene Vancouver Edmonton Calgary Winnipeg Montreal Halifax Toronto Four STM-4 lightpaths for links to STTL and Chicago in varied combinations Flexible provisioning of lightpaths for links to Seattle or Chicago will be realized TANet2 /TWAREN Taipei Possible Logical Connections
13 TWAREN Grid Applications Our Center is heavily involved with grid activities. Ongoing projects include: Eco-Grid National Land Use Monitoring & Analysis Structure Monitoring of Buildings for Earthquake Risk Flood Forecasting & Monitoring SARS Grid 3D Imaging of Neural Structure of Fruit Fries …Other national grid activities under development
14 TWAREN Flexible lightpath provisioning will be deployed for both TANet2 & TWAREN Will permit Taiwans R&E community to engage in transnational collaborations, in e- science and other applications. The lightpath from Seattle to Chicago, designated as Taiwan Light, will join the other networks at TransLight. TaiwanLight stands to participate in the US National Lambda Rail and e-Science Projects.
