token-ring network

token-ring network
   A LAN with a ring structure that uses token passing to regulate traffic on the network and avoid collisions.
   On a token-ring network, the controlling network interface card generates a token that controls the right to transmit. This token is continuously passed from one node to the next around the network. When a node has information to transmit, it captures the token, sets its status to busy, and adds the message and the destination address. All other nodes continuously read the token to determine if they are the recipient of a message. If they are, they collect the token, extract the message, and return the token to the sender. The sender then removes the message and sets the token status to free, indicating that it can be used by the next node in sequence.
