token bus - Free On-line Dictionary of Computing (26 May 2007) :

  token bus
  
     <networking> (IEEE 802.4) A networking protocol which mediates
     access to a bus topology network as though it were a token ring
     .  This eliminates the collisions found in carrier sense 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.
