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


Slide5 l.jpg

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


Slide6 l.jpg

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

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

Network Architecture

Design Goals

  • Carrier-class architecture and equipment

  • High-speed backbone, multi-serveice PoPs

  • Dual circuits to guard against failure

  • Scalable and flexible

  • Fiber ownership or control


Slide11 l.jpg

Circuits by Chunghwa Telecom

  • 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.

Circuits by EBT

(Eastern Broadband Telecom)

  • A new telecom company formed after deregualation

  • Fibers deployed along the railroads.

  • In cooperation with Taiwan Railway Company which has extensive rails system.

  • Dual routing and protection also provided by the company’s 10G DWDM network

Imaging neural structures l.jpg
Imaging Neural Structures

  • A collaboration between Cold Spring Harbor Laboratory (US) and Taiwan

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

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