dual-homed

networking 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.
