token ring
A computer {local area network} arbitration scheme in which
conflicts in the transmission of messages are avoided by the
granting of "tokens" which give permission to send. A station
keeps the token while transmitting a message, if it has a
message to transmit, and then passes it on to the next
station.
Often, "Token Ring" is used to refer to the {IEEE 802.5} token
ring {standard}, which is the most common type of token ring.
