  • System and associated method for scheduling transport of variable bit-rate data over a network
    Patent number: 6950399
    Abstract: A method is provided for transmitting data packets over a bi-directional contention and reservation based network. The network includes an operably linked system controller for receiving upstream channel packets and originating downstream channel packets. At least one operably linked remote terminal is included for receiving the downstream channel packets and originating the upstream channel packets. The system controller provides periodically allocated grants to the at least one remote terminal in the downstream channel for scheduling data packet transfers in the upstream channel. The periodically allocated grants have a fixed bandwidth size. The system controller also provides dynamically allocated grants to the at least one remote terminal in the downstream channel upon request of the at least one remote terminal for scheduling data packet transfers in the upstream channel. The dynamically allocated grants are of a requested bandwidth size.
