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.
