TaiWan Advanced Research and Education Network (TWAREN): Is the only national academic and research backbone in Taiwan tha

t 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 ele

mentary schools in Taiwan. Is operated by Ministry of Education (MOE), Taiwan.

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

1313

Design Considerations IP and optical network being integrated into one One backbone providing services for two virtual netwo

rks and dedicated lightpaths Optical at the core, routing at the edge Packets transmitted over Lightpaths between GigaPO

P and core nodes Multi-point communication among core nodes with M

PLS technology Reuse the equipment to save the cost Automated protection using UPSR/Spanning Tree for
