- The Widely Integrated Distributed Environment (WIDE) project was initiated in
- July 1987 by a group of researchers led by Professor Jun Murai. The project was
- designed to provide a testbed for the development of large-scale distributed
- systems technologies, and was initially constructed by interconnecting several
- campus networks. The WIDE Internet has since provided a basis for Japanese
- computer science researchers to gain practical experience in advanced
- networking. The WIDE project operates as a non-government network with funding
- support from about 25 private companies.
-
- The WIDE project sponsors a consortium to study various computer issues
- including protocols, operating systems, computer security, ISDN technologies,
- home computing, mobile computing, satellite data communications, distributed
- applications and internationalization of computer software. Their research
- results are annually published by the project and the resulted software are
- also distributed.
-
- The WIDE Internet is composed of a variety of links, including voice grade
- leased lines, 64Kbps and 192Kbps digital leased lines, and ISDN. Currently,
- 52 user organizations, including universities and private companies are
- connected to six operation centers through 64Kbps to 192Kbps leased lines. The
- backbone also passing a traffic of other research networks such as JUNET (Japan
- University Network) or JAIN (Japan Academic Inter-university Network) which
- does not have a long haul nation-wide connectivity. The WIDE project has been
- providing connectivity to other networks, such as the University of Tokyo
- International Science Network(TISN), NACSIS Science Information Network(SINET),
- and BITNET-JAPAN. The WIDE Internet supports TCP/IP as the basic protocol.
-
- WIDE operates in conjunction with the Pacific Area Computer Communication
- (PACCOM) project to provide international inks for Japanese researchers using
- 192Kbps under-sea cable via University of Hawaii to NASA Ames, FIX-WEST.
-
- The actual location of WIDE internet backbone nodes (WNOCs) are Sendai,
- Fujisawa, Tokyo, Kyoto, Osaka and Fukuoka, and the backbone is formed by
- connecting these WNOCs via 64Kbps lines (192Kbps between Tokyo and Fujisawa),
- which is backuped by the ISDN technology developed by WIDE project itself.
