Abstract
A router includes a communications bus, a second bus, and at least two processors. The second bus transfers ready status data from ports connected to the communications bus. The processors are connected to the communications and second busses. One of the processors controls the communications bus at each time. Each processor transfers control of the communications bus to another processor in response to receiving a request for control from the other processor.
