ABSTRACT:
A token passing media access protocol provides distributed time scheduling. The token provides an indication of each time at which a network device is to perform a cyclic or time critical operation. The token also provides an indication of system time to enable all devices on the network bus to be synchronized. The format of data transmissions on the network bus employs a shortened device address when referencing the device as a source. The source address corresponds to a unique portion of the device address.
