Distributed Network Service Provider Internet eXchange Point 2 (NSPIXP-2), the largest Internet exchange point in Japan, launches operations at six locations in Tokyo Name changed to dix-ie (Distributed IX in EDO) as the distributed NSPIXP-2 is implemented

On March 28, 2003, the WIDE Project (General Chairperson, Jun Murai, Director, SFC Research Center, and Professor, Faculty of Environmental Information, Keio University) launched operations of the distributed dix-ie, the largest Internet exchange point in Japan, at six locations in Tokyo. With the launch, the name NSPIXP-2 was changed to dix-ie (Distributed IX in EDO).

dix-ie, the largest Internet exchange point in Japan, is the IXP (Internet eXchange Point) for an experiment in interconnectivity technology that has been conducted by the WIDE Project under the name NSPIXP-2 since 1995. At present, over 60 Internet service providers (ISPs) are interconnected in the KDDI Corporation?s Otemachi Building, located in Otemachi, Tokyo. Since June 2001, the WIDE Project has conducted research and development on the adoption of IPv6 and distributed connection points for the implementation of multiple connections in Tokyo, launching operations on March 28, 2003. With the launch, the name NSPIXP-2 was changed to dix-ie (Distributed IX in EDO).

From the KDDI Corporation Otemachi Building (Chiyoda Ward), dix-ie uses optical fiber to connect five companies in five different locations: MCI WorldCom Japan Ltd. (connection point: Chuo Ward); Mitsubishi Electric Information Network Corporation (Shinagawa Ward); NTT Communications Corporation (Chiyoda Ward); POWEREDCOM Inc. (Koto Ward); and AboveNet Japan Inc. / Global Solution K.K. (Chuo Ward). Gigabit Ethernet and 10-gigabit Ethernet technologies are adopted to achieve broadband connection speeds of 4Gbps to 10Gbps.

With the launch of expanded, distributed IXs, content service providers in each location will promote broadband under an improved content distribution environment for ISPs connected to dix-ie. Furthermore, ISPs and content service providers can freely select the locations where services are provided.

The WIDE Project has been conducting research and development into and verification experiments on broadband and stable operation technology for interconnected points on the Internet, as well as experiments on interconnected points with IPv6, the next-generation Internet protocol. The WIDE Project considers the operation of dix-ie a key research theme for the development of the next-generation Internet, and is striving to move ahead on research and development in cooperation with ISPs, content service providers, and data centers.
