        6.3  INTERNET 2 AND THE    NEXT-GENERATION INTERNET

        The Internet has spread throughout the world rapidly. However, it has not provided
        high-speed transmission. This makes it very difficult to transmit multimedia infor-
        mation, such as images, motion pictures, and 3D images via the Internet. Demand
        is growing strongly to enhance the Internet.
            In response,  in  1996  two  initiatives  were announced  by the United  States
        to  enhance  the  efficiency  of  the  Internet  substantially:  Internet  2  and  the  Next-
        Generation  Internet, The  Internet  2 project  was  initiated  by the  university  com-
        munity  of  the  United  States.  The  Next-Generation Internet  was  initiated by  the
        Clinton Administration.


        6.3.1 Internet 2
        Internet 2 is an intracampus high-speed  network, called  GigaPOP (gigabit  capac-
        ity point of presence), providing a variety of Internet  services.  GigaPOP is  linked
        to  a high-speed  backbone  network  BNS,  which  plays  a role  as collective entity
        (CE). In general, the transmission capacity of GigaPOP  is about 622 Mbps.


        6.3.2 Next-Generation Internet
        The  Next-Generation Internet  (NGI)  aims  to be  a  speedier  communication  net-
        work,  its  goal  being  to provide  100-1000 times  the  transmission  speed  of  con-
        ventional  Internet  access.  Using  NGI,  real-time  multimedia  services  such  as a
        high-quality videoconference service are available. The number of users who have
        access to NGI has been  increasing  with the quality of services.  For example,  the
        current 64-Kbps Internet  service  has been  enhanced  to 6.4 Mbps or 64 Mbps. At
        64 Mbps,  motion  pictures  can  easily  be transmitted  in real  time.  The  1.5-Mbps
        Internet  service has  been  enhanced  to  150 Mbps or  1.5 Gbps, enabling  the  large
        amount of information produced by a supercomputer to be transmitted in real time.


        6.4 GLOBAL INFORMATION INFRASTRUCTURE

        Following  the Clinton Administration's  1993  announcement of the Nil, the ad-
        vanced countries,  such as Japan,  the United  Kingdom,  Germany, and France,  an-
        nounced their own information superhighway initiatives.  Based on Nil, in  1994 the
        United States proposed a global information infrastructure (Gil) at the  plenipoten-
        tiary meeting of the International Telecommunications  Union (ITU). According  to
        the Gil initiative, anybody in any country can access Gil and free competition  can
        exist, Gil can be enhanced without disturbing  conventional  service operations, and
        universal service can be provided through GIL
            In  1994,  at  the  Third  International  Conference  on  Broad  Islands,  held  in
        Hamburg, Germany, the programs, perspectives,  and activities and  technological
