DUAL-ATTACHED


Meaning of DUAL-ATTACHED in English

The form of FDDI interface where a device is connected to both FDDI token-passing rings, so that uninterrupted operation continues in the event of a failure of either of the rings. All connections to the main FDDI rings are dual-attached. Typically, a small number of critical infrastructure devices such as router s and concentrator s are dual-attached, whereas host computers are normally single-attached or dual-homed to a router or concentrator.

For example, a ring could be formed between a single router and two concentrators (all dual-attached) then all other components that need to be fault-tolerant (typically file servers) can be dual-homed to both concentrators.
