token bus

networking (IEEE 802.4) A networking protocol which mediates

access to a bus topology network as though it were a tokenring. This eliminates the collisions found in carriersense collision detect protocols. Nodes can be configured

to pass the token in any order, not necessarily related to

their physical ordering on the bus. The token is sent from

one node to its successor in the logical ring by broadcast on

the bus and is ignored by the other nodes.
