The TWAREN InitiativeTWAREN 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


Ground BreakingTWAREN 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 costCompetition makes fiber provisioning

possible, albeit partial ownershipOur twin project, KING, also generously

funded, will be the primary driver for scientific applications


Core Nodes in Science ParksThree 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 functionThe 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

A Hybrid NetworkTWAREN is a new hybrid network with 10G

POS and DWDM technologies at its coreDual 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

The CHT 10 G DWDM Network offers 10 G optical channels.The company's two main networks on the western shore are built with single mode, 96-fiber capacity. Nortel OPTera Long Haul 1600 were installed on both main networks. It is capable of delivering 40λ of 10 Gbps optical channels.

The Taiwan NSC awarded one million US dollars to Prof. Chiang Ann-Shyn of NCTU for probing the brains of fruit flies

Mutants (memory) are supplied by CSH The NCHC does the image processing and b

uids the database online (led by Dr. Chang-Huain Hsieh)

Analyzed images will be stored at the NCHC, a case in collaborative, distributed storage
