TANet2 and TWAREN• TANet2 is a national research network, in oper
ation 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.

Grid ApplicationsOur 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
14TWAREN
• Flexible lightpath provisioning will be deployed for both TANet2 & TWAREN
• Will permit Taiwan’s 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.
