dual-homed
     
         A kind of connection to a {FDDI} network where a
        {host} is simultaneously connected to two separate devices in
        the same FDDI ring.  One of the connections becomes active
        while the other one is automatically blocked.  If the first
        connection fails, the backup link takes over with no
        perceptible delay.
     
        A dual-homed device can tolerate a fault in one of its "homes"
        whereas a {dual-attached} device can tolerate a fault in one
        of the rings.
