Abstract
In a communication system with a bandwidth-on-demand processor, which may be power limited and connected to a myriad of terminals via relatively long delay paths, and another processor, which is connected to a few terminals via relatively short delay paths, an approach for effectively coordinating the processors is disclosed. A bandwidth controller receives a message requesting bandwidth from a remote processor and selectively grants the bandwidth request. The bandwidth controller transmits an assignment message that specifies a bandwidth allocation to the remote processor, and concurrently transmits a control message. A switch is configured to forward the assignment message to the remote processor. A controller is coupled to the switch and is configured to receive the control message, wherein the control message provides bandwidth allocation. The above arrangement has particular applicability to a satellite communications system.
