  3. Introduction to TWAREN & TANET • TaiWan Advanced Research and Education Network (TWAREN): • Is the only national academic and research backbone in Taiwan that provides layer one optical lightpaths and layer three routing and peerings. • Provides production and research network connection among universities, research centers in Taiwan and international Internet2 partners. • Replaces TANet2 as an MOU partner of Internet2 and part of APAN-TW. • Has the international circuits with state-of-the-art optical technologies called TAIWANLight. • Is operated by National Center for High-Performance Computing (NCHC) in Taiwan. • Taiwan Academic NETwork (TANET) • Is the academic network connecting colleges, high schools and elementary schools in Taiwan. • Is operated by Ministry of Education (MOE), Taiwan.

  12. Drivers for New Architecture • Lease of circuits due in October 2006 • Network consolidation for cost saving • Need for next generation network testbed • Better network performance • Network utilization and operations efficiency • No single point-of-failure, highly fault tolerant • Network scalability • More demands of integrating optical lightpaths with IP services

  13. Design Considerations • IP and optical network being integrated into one • One backbone providing services for two virtual networks and dedicated lightpaths • Optical at the core, routing at the edge • Packets transmitted over Lightpaths between GigaPOP and core nodes • Multi-point communication among core nodes with MPLS technology • Reuse the equipment to save the cost • Automated protection using UPSR/Spanning Tree for link failure • Lambda-based network

  21. Summary In order to provide better network and operations efficiency, as well as next generation network testbed, NCHC in Taiwan is currently in the midst of network re-design to consolidate the Taiwan’s R&E network backbones with the following capabilities: • Adaptation to different network policies • Use current equipment for cost minimization • Services of virtual networks and dedicated lightpaths • Full protection for any single point of failure • Lightpath allocation for automated protection • Conforming TMN architecture and functionalities • Hybrid Optical Packet Infrastructure (HOPI) • Support for emerging network technologies • Lambda-based network as next generation network testbed
