In the early nineties, the US Government actively promoted the establishment of the National Information Infrastructure (NII) to enhance the competitiveness of the US industries in global markets. The US spent 4.6 billion dollars in the period 1992-1996 to implement the High Performance Computing and Communications Initiatives(HPCC) to promote the development of the next generation technologies and applications in telecommunications. In 1997, the Next Generation Internet (NGI) program was unveiled with a budget of 85 million dollars in fiscal year 1998. The high-speed NGI network was to connect more than 100 sites nationwide, thus to establish a widely accessible test-bed. As a result of these initiatives, a noticeable competitiveness of the US industries had been achieved.

slide3

The Japanese Government took initiatives to catch up the US and other frontrunner countries. Recognizing the importance of developing advanced research facilities with very high-speed network systems in promoting research and development of high-speed networking and high-performance application technologies, the Japanese Government allocated a 57.3 billion yen (477.5 million dollars: US$1 = \120) budget in the fiscal year 1998 to the Ministry of Posts and Telecommunications. Financed by the Ministry with this budget, the TAO, Telecommunications Advancement Organization of Japan, designed and developed the JGN, Japan Gigabit Network, as a nationwide research and development facility.

slide4

The Japan Gigabit Network is comprised of five laboratories and a high-speed backbone network of optical fiber with a maximum transmission rate of 2.4 Gbps. The backbone is connected via ten ATM (Asynchronous Transfer Mode) switches to fifty-four connecting nodes located in major cities throughout Japan. It provides universities, industries, and local and national government agencies with test-beds open to both public and private bodies for collaborative research and development of advanced networking technologies and applications. A public announcement is made every four months to invite applications for the use of the laboratory facilities, while applications for the use of the backbone network can be filed throughout the year.

Community Room

This room is suited for short-term use by small groups of local communities, schools, venture businesses, or local industries for seminar classes or training courses. It is also used as a visitors assembly hall where an introductory briefing is given about the facility prior to the guided tour. Twenty laptop personal computers and a 50-inch plasma display are provided to provide participants an opportunity to use PCs and see the impressive view on a large display. A teleconference system is installed in this room and is regularly used in practice by our staff connecting the Kitakyushu and the Keihanna Gigabit Laboratories via the ATM backbone of the Japan Gigabit Network. Also placed in this room are four commercially available 64 kbps-class videophones. Visitors can witness the high quality of moving pictures made possible by the advanced technology. The Tsukuba Gigabit Seminar is held in this room. The teleconference system is used for the seminar to invite participation in it from the Keihannna and Kitakyushu Gigabit Laboratories in the bi-directional mode. The seminar is also distributed simultaneously on the Internet.

slide13

Digital Content Production Facility

All the equipment and software necessary for the development of high performance interactive digital content are available, including ten digital video cameras. A video studio equipped with a lighting system and a computer and display console can be used for camera and editorial work using image data library. Acoustic synthesizing equipment is available for the creation of acoustic materials of digital voice and music and for research and development of technology for synchronizing them with motion video. Six desktop personal computers with 2D and 3D graphics animation software for the creation of computer graphics are available. Video editing equipment is to be used for editing the video content with the aid of available visual materials. Sound editing equipment is used for synchronizing the acoustic materials with video content

slide17

Long Distance Optical Transmission Test Facility

Fifteen cable wheels, each carrying a 10-km long fiber optics cable with 24 optical fibers inside, are stored on the roof of the headquarters building, exposed to the open sky. These are used to simulate a long-distance backbone cable in commercial use. A line of optical fiber as long as 3,600 km could be realized if all the fibers were connected in series. In current practice, however, the longest optical fiber used for testing is 600 km. Tests may include the evaluation of various line characteristics such as dependency on the wavelength, the integrity of links connecting network interface equipment, and the feasibility of application software services. In addition to the cable wheels, the facility consists of wavelength division multiplexing equipment and end terminal equipment for optical transmission at 10 Gbps.

slide20

Home-Networking Development and Test Facility

Various items of equipment are available for research and development as well as for the evaluation of home-networking technologies to accommodate integrated customer services for access to high-speed networks. Topics of research and development may include installation of end system interfaces for high performance standards such as IEEE1394, design and evaluation of wired home-network, particularly with optical fibers, and of wireless broadband systems. Also included is the system evaluation for electronic acquisition of authorized certificates by the end user at the home-network terminal. One example is a certificate of residence from a municipal office. Here, personal security and recognition is an important subject of research. A pneumatically suspended optical table and an electromagnetic anechonic chamber insulated from electromagnetic interference are available.

slide24

High Speed Image Transmission Test Facility

Research and development of image processing and transmission technologies for HDTV is being conducted. High-speed video transmission tests are being conducted between the Keihanna and Tsukuba Gigabit Laboratories through the Japan Gigabit Network backbone. The purpose of the current research is to create a seamless virtual space in which conference attendees at multiple sites are put together for teleconferencing. Techniques to achieve better face-to-face communication in a teleconference are being developed such as a method of maintaining the same eye-level contact.

slide27

Distributed Computer Resources Networking Facility

Two systems of high-speed computers (one vector and one scalar) are installed in this room; each has its own advantages and/or disadvantages. The facility looks more like a usual computer center we can see everywhere. The difference is that they are implemented in a network system. Protocols and techniques are sought to make the best use of the advantages of those distributed heterogeneous computer resources over the network. A large-scale simulation of molecular orbits in computational chemistry is currently being undertaken as a research project.

slide30

ATM Network Systems Test Facility

An ATM (Asynchronous Transfer Mode) switching network is available. An ATM-ring system consisting of multiple local networks and their satellites is connected to the backbone network via an ATM switch. It may be used for the development of the technology for ATM network transmission and connection to the backbone network via ATM switches. It may also be used for the evaluation of error rate, jitter, and latency of transmission. Terminal ports are available for serial interface for analog four-wire circuits, digital 1.5 Mbps and 6 Mbps cables, and for the interface for ATM 155 Mbps switches.

slide33

High Quality Image Processing and Evaluation Facility

Systems of servers and end equipment are available for the development and evaluation of high quality images. A 110 inch-type large screen and HDTV projectors are installed in a monitoring room. A research project for an advanced HDTV system is currently being undertaken and is used for public demonstration. The advanced system achieves a very high quality image with a resolution and brightness that are both four times higher than the conventional HDTV. It allows us to make detailed observations of electronically accessed art works from virtual libraries or museums. Advanced techniques for searching library data and for intellectual property right management, including electronic watermarks, are important topics of research.
