The greatest risk to a bus network is that the bus itself might become inoperable. When a device needs to transmit, it reserves the token for the next trip around, then attaches its data packet to it. A token ring station waits for permission to speak a token but forwards all traffic it receives to the next member of the ring until it gets one. Token bus is as far as i know the theory that token rings transmission is based on.
The token still circulates around the network and is still controlled in the same manner, however, using a hub or a switch greatly improves reliability because the hub can automatically bypass any ports that are disconnected or have a cabling fault.
