How does a Token-Passing Protocol works?
The token-passing protocol relies on a control signal known as the token. A token is a 24-bit packet that circulates throughout the network from NIC to NIC in an orderly fashion. If a workstation needs to transmit a message, first it must seize the token. At that point, the workstation has complete control over the communications channel. The existence of only one token eliminates the possibility of signal collisions. This means that only single station can speak at a time.
