2. Topology of the Internet in Japan  Disaster in Tokyo will affect regional residents even when there is no damage in that region  Throughput must be worse in many cases because of routing detours  Tokyo gains more and more Facilities, Engineers and Capital Tokyo has gained enough already RIBB Topology of JP Conclusion Regional Activity JGN AV streaming Data Center DISTIX About RIBB

3. Regional Activities in Japan  Many noteworthy activities in the Regions Toyama, Tohoku, Yamanashi, Tokai, Okayama and Hiroshima  Not enough collaboration among them even they know each other RIBB Topology of JP Conclusion Regional Activity JGN AV streaming Data Center DISTIX About RIBB

4.  For research and development towards the next generation  build on ATM tech.  Max 2.4 Gbps link  Free use no commercial traffic JGN (Japan Gigabit Network) You finished the background

5. RIBB: Regional Internet Backbone  Since May 1999  Interconnection of Regional Activities Researchers and Developers Projects Regional Networks  Network is Constructed on JGN RIBB Topology of JP Conclusion Regional Activity JGN AV streaming Data Center DISTIX About RIBB
