Abstract:
In a token bus system a node with the token can transmit on the bus a packet that contains two destination addresses. One address specifies the node that should receive the data component (payload) of the transmitted packet. The other address specifies the node that should receive the token. The network protocol specifies that a node with the token must immediately transmit a packet containing just the token or a packet with token and data if it has data to send. When no data is being passed from one node to another on the network, the token may be passed from one node to the next in order. Each node will pass the token to the next highest node number. If a node has the token has some data for sending it transmits a packet with the token for the next node and data for any of the nodes. The bus system requires every node to receive all packets and process them to determine whether the token or the data (or both) is destined for that node.
