  2. What’s the Tsukuba WAN ? Tsukuba WAN is the network for research collaboration and cooperation among industry, university and government. It links with many institutes in Tsukuba area by ultrahigh- speed access ring network. As a result, they are able to use almost recourse of research institutes in Tsukuba, such as supercomputer, large-scale database, and computer simulations software. Construction of Network began in 2000, and operation started at May 2002. The Tsukuba WAN symposium was held at May 2, 2002 as Opening ceremony. At the symposium, some program occurred such as the presentation on the results of research, which was using Tsukuba WAN, and discussion about the concept. http://tsukuba-wan.mexttci.go.jp/

  3. Outline Tsukuba Science City map （Optical ring length 50km） The ultrahigh-speed 10G (total bandwidth is 570Gbps) access ring network for research collabolation, by the connection with supercomputer of research institutes and universities in Tsukuba. Adoption of advanced network technology, such as Wavelength Division Multiplexing by OADM (Optical Add-Drop Multiplexer) Research, development and field verification about technology such as interface between supercomputer and network, and security of each large scale simulations High Energy Accelerator Research Organization NTT Access Network Service Systems Laboratories National Institute for Land and Infrastructure Management National Research Institute for Earth Science and Disaster Prevention University of Tsukuba Tsukuba Center for Institutes Tsukuba Gigabit Laboratory National Institute for Materials Science 光伝送路 Gbit-SW Router SuperComputer National Institute of Advanced Industrial Science and Technology National Institute for Environmental Studies MAFFIN
