Abstract:	The Japanese academic backbone network has been providing a variety of multilayer network services to support a wide range of research and education activities for more than 700 universities and research institutions. The new version, called SINET4, was launched in 2011 in order to enhance the service availability and the network bandwidth as well as to expand the service menu. Its enhanced service availability was unexpectedly verified by the disastrous March 11 Great East Japan Earthquake, when the network managed not to stop service operation even after the earthquake. This paper describes the design and implementation of SINET4 in terms of multiple service provision, network resource control and management, and high reliability from physical level to network management level. The impacts of the huge earthquake are also reported. [ABSTRACT FROM AUTHOR]
