Supporting social infrastructure with both hands.

Research Operation

The Internet is a technology that knows no boundaries. Its expansion of scale gives rise to innovative technologies, and changes in optimal methodologies make it necessary to conduct case-by-case implementation experiments. The WIDE Project with its motto of "Research on our left hand, operation on our right hand." is the first in Japan to establish a collaborative research foundation, the "WIDE Internet" on the Internet. While operational, the "WIDE Internet" also functions as a site for experiments. Research results are fed back to operations to build more efficient network environment for society and the business community.

研究Toward the new and unknown age of ubiquity.

Mobile and Auto-ID technologies are expanding the network access base through the practical application of IPv6.
The ultimate aim of the project , namely the realization of a "large scale distributed computing environment", is nearing the age of ubiquity.

The pursuit of the possibilities of in built car computers
iCAR (Internet CAR)

Research is currently being undertaken into information platforms necessary for the development of mobile communication technologies required to provide a link between automobiles and the Internet and into the application of such technologies. Research primarily consists of practical experimentation involving the provision of traffic and weather information by transmitting and accumulating information held by in-built car sensors over the Internet.

The construction of new infrastructures through the use of satellites
AI3 (Asian Internet Interconnection Initiatives Project)

The WIDE Project is providing broadband networks to countries lacking cable network infrastructure such as countries in Southeast Asia through the use of satellite networks. An Internet architecture has been established maximizing the strengths of satellite communications, namely portability, geographic coverage, and dynamic circuit settings, and has been applied to the current Internet infrastructures making possible communications that were impossible using conventional network platforms.

Global sharing of education
SOI (School of Internet)

As of March 2007, there are 22,042 students (over half of them adults) enrolled with SOI. Students have accumulated and benefited from over 2000 hours of Internet related lessons including special lectures provided by university professors and world renowned researchers. Launched in 1997, SOI has continued to grow providing joint lessons by lecturers in Japan and the U.S. in 1998. In 2000, SOI began providing real-time lessons on an experimental basis, and in 2001, launched the SOI Studio Project with the aim of setting up and establishing the framework for a next generation remote learning studio. The SOI-Asia Project, launched in 2001, has been concentrating on broadcasting lessons through the use of satellite links, and as of March 2007, is broadcasting real-time and archived lessons to 26 universities and research institutions in 12 countries.

Creating firm links between cyberspace and real Space

Involved in researching, designing, implementing, and experimenting with systems which process information regarding an object to which a unique identifier (ID) capable of individual recognition has been attached over the Internet. The results are forwarded to the Auto-ID lab for further research and standardization.

Promoting the Deployment of IPv6 with Technology

A variety of research and development is currently underway for the implementation, verification and deployment of IPv6. Concluding in March 2006, the KAME Project succeeded in implementing an advanced IPv6/IPsec for BSD-based operating systems, establishing the foundation for the deployment of IPv6 technology. The USAGI Project has also contributed to the implementation of IPv6 on Linux-based systems, further contributing to the deployment of IPv6. Yet another research project, the TAHI project has also provided high-quality verification procedures for various IPv6 devices, including the implementation of IPv6 on BSD and Linux-based systems, and has become to act as a standard body for the verification of IPv6 technologies. The WIDE (IPv6 Fix) Project is also making progress in identifying and resolving issues concerning the migration to IPv6.

Practical application of IPv6 in mobile communications

We are currently involved in the research and development of mobile communication technologies required for the deployment of IPv6 mobility in today's society. The group is engaged in the research and development of the necessary fundamental technologies for mobile communications such as Mobile IPv6 and NEMO aiming for the development of practical protocols and the establishment of practical operating technologies.
