4. National Center for High-performance Computing4 The TWAREN Initiative  TWAREN is part of a comprehensive, six- year national plan formulated by the government to stimulate creativity and foster talents.  Pairing with a twin project, KING (Knowledge Innovation National Grid), the two serve as the enablers in facilitating scientific discoveries and knowledge creations, in global collaborations and resource sharing.  Both projects at our Center began January, 2003

5. National Center for High-performance Computing5 Ground Breaking  TWAREN signifies a very big advance for Taiwan’s research network since TANet2.  It breaks many new grounds for R&E networks in Taiwan:  The telecom deregulation, three years hence, has effectively lowered cost  Competition makes fiber provisioning possible, albeit partial ownership  Our twin project, KING, also generously funded, will be the primary driver for scientific applications

6. National Center for High-performance Computing6 Core Nodes in Science Parks  Three of the four core nodes are strategically placed in Taiwan’s science parks to serve industrial R&D besides academic research  Each node is assigned a primary function  The NCHC HQ in the Hsinchu Science- based Industrial Park, will be a resource center for computing  Our southern branch, to be completed in 2004, will house the Network Operation Center  An additional office, to be built in central Taiwan, serves as the Knowledge Center

8. National Center for High-performance Computing8 A Hybrid Network  TWAREN is a new hybrid network with 10G POS and DWDM technologies at its core  Dual circuits form the backbone. Two local carriers, Chunghwa Telecom and Eastern Broadband Telecom, each provides a 10 G POS network linking the four core nodes.  There are eleven GigaPoPs, each links to the core node at 10 GbE  Total bandwidth for the backbone is 80 G. Combined with fibers, the total bandwidth for the GigaPoPs is 205 G
