Information on Token-passing
Token-passing is a media access technique in which a small set of bits called the token is passed between network devices. Each device receives the token and passes it on to a neighbour. On receipt of the token, a device is allowed to transmit data onto the network. The Token must then be released to allow other devices the opportunity to transmit. Token-passing therefore forces a form of time-division multiplexing on the network and is a more orderly access technique than carrier-sense multiple access/collision detection (CSMA/CD). Token passing can be implemented on bus local area networks (LANs), but is most commonly implemented on ring topologies.
