Abstract:
A method for exchanging data in a communications system that includes a controller coupled to a switch, the method comprising:receiving a message requesting bandwidth from a processor; selectively granting the bandwidth request by a bandwidth controller; transmitting an assignment message that specifies a bandwidth allocation based upon the granting step to the processor; and initiating transmission of a control message to the controller to provide bandwidth allocation information concurrently with the transmitting step; wherein the communications system includes a satellite that includes the controller and the switch, the message requesting bandwidth in the receiving step being transmitted over a communication network that is separate from the satellite communications system; and wherein the switch includes a plurality of queues, each of the queues having a threshold value and storing data corresponding to a plurality of downlink cells based upon the threshold value, the controller including a plurality of counters corresponding to the plurality of queues.
