The TWAREN Initiative q. TWAREN is part of a comprehensive, sixyear national plan formulated by the government to stimulate creativity and foster talents. q. 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. q Both projects at our Center began January, 2003 National Center for High-performance Computing 4

Ground Breaking q. TWAREN signifies a very big advance for Taiwan’s research network since TANet 2. q It breaks many new grounds for R&E networks in Taiwan: q. The telecom deregulation, three years hence, has effectively lowered cost q. Competition makes fiber provisioning possible, albeit partial ownership q. Our twin project, KING, also generously funded, will be the primary driver for scientific applications National Center for High-performance Computing 5

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

A Hybrid Network q. TWAREN is a new hybrid network with 10 G POS and DWDM technologies at its core q. 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. q. There are eleven Giga. Po. Ps, each links to the core node at 10 Gb. E q. Total bandwidth for the backbone is 80 G. Combined with fibers, the total bandwidth for the Giga. Po. Ps is 205 G National Center for High-performance Computing 8
