Abstract:
A communications system controlling the admission of resources to a peripheral bus in the communications system, the communications system comprising:a peripheral bus having a finite bandwidth; a plurality of resources, connected to the peripheral bus, and configured to send and/or receive data over the peripheral bus; and a communications controller connected to the peripheral bus, said communications controller adapted to: monitor the actual data transfer rate on the peripheral bus of each of said plurality of resources having a bandwidth guarantee on the peripheral bus for data communications; obtain a utilization value representative of the extent to which the plurality of resources utilizes the guaranteed bandwidth on the peripheral bus upon receiving a quasi-isochronous request for admission to the peripheral bus from an additional resource; and admit the additional resource to the peripheral bus if the utilization value indicates that the amount of unutilized bandwidth on the peripheral bus is approximately sufficient to satisfy the data transfer rate of the additional resource.
