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.

Supporting the dawn of the Internet Age

Operation of the "WIDE Internet" started as a TCP/IP based experimental platform run by the WIDE Project in 1988, four years before the appearance of WWW. Presently the project has served to enhance broadband environments and is proving itself as a platform for the validation of a large number of experiments. We operate the JP DNS server in 1989 and have since then sustained the JP zone.


Expanding research platforms
The WIDE Internet

The WIDE Internet from its humble beginnings utilizing a single leased 64kbps line, has undergone broadband incorporation on an leased OC3 international line and GbE(Gigabit Ethernet) connections. In addition to that, the network has been linked to research networks around the world and commercial ISPs forming an important platform for joint research.

Challenge toward a next generation Ethernet
10G Ethernet

The WIDE Project has established the framework for wide-area Ethernet long-distance data transfer and has developed operational technologies and are putting to use the results of this research to construct and conduct joint verification experiments for a large-scale, next generation network (10Gbps Ethernet).

Ultra-wide band optical network
technologies T-LEX (Lambda Internet)

The IEEAF (Internet Educational Equal Access Foundation) operating a next-generation research and education network, commenced the operation of a Japan-U.S. 10Gbps Lambda based network in June 2004. The T-LEX (Tokyo-Lambda Exchange) constructed in accordance with the launch of this network serves as a public Lambda Internet exchange point. (Interconnection point)

Connecting IPv6 technologies to ISP
NSPIXP (Network Service Provider Internet eXchange Point)

The NSPIXP started operations in 1994 on a single Ethernet Hub experimenting interconnection technologies with the aim of creating more effective Internet operations in Japan. Subsequently with the increased use of the Internet, the system was migrated to NSPIXP-2 using FDDI and NSPIXP-3 commenced operations connecting multiple points in Osaka with the Gigabit Ethernet. NSPIXP was later migrated from FDDI to the Gigabit Ethernet/Fast Ethernet, and in April 2004 changed its name to DIX-IE (Distributed IX in EDO) and commenced distributed operations. NSPIXP was established to further promote the adoption of IPv6 and now functions as a connection point for Japan's primary Internet service providers.

Operation of DNS in the Asia-Pacific region
DNS (Domain Name System) -M Root DNS Server -

Ever since the dawn of the Internet, the WIDE Project has been operating the JP DNS. As part of our responsibility in contributing to the development of the Internet we have been operating the M Root DNS server since 1997.
