   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.
