High Performance Parallel Interface
     
         (HIPPI, previously HPPI) A
        {connection-oriented}, point-to-point networking {standard}
        using {circuit-switching} technology at a speed of 800 Mbits/s
        or 1.6 Gbits/s (simplex or full-duplex).  HIPPI is often used
        for short distances (up to 10km depending on cable type) to
        connect a {supercomputer} to {routers}, {frame buffers},
        {mass-storage} peripherals and other computers.
     
        HIPPI was developed at {Los Alamos National Laboratory} and is
        now {ANSI} standard X3T9/88-127.  Standards for
        interconnecting with {ATM}, {SONet}, and {fibre channel} are
        in development.
