  2. OUTLINE • About TWAREN • Design and Planning • The TWAREN Architecture • Dual-Circuit Provisioning by Two Local Vendors • TANet2 and International Connectivity • Collaborations

  3. TWAREN TaiWan Advanced Researchand Education Network

  4. 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. 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. 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

  7. Computing Center Knowledge Center Taipei Tainan Hsinchu Taichung Network Operation Center Core node equipment Functions Assigned

  8. 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

  10. 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

  11. 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.

  21. Three Network Systems • Producation Network – provides the usual academic connectivity and utilities • Research Network – provides advanced technologies (IPv6, MPLS, Multicast…) and experimental networks, to be backed up by production network • Optical Network – provides Layer1 communications among peers
