Abstract
In a satellite gateway, data is transmitted over a downstream channel at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. The downstream data is parsed to extract data packets. The data packets are then loaded into packet queues based on an identifier within such packets. The queues represent a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers that may also be based on the current signal quality at a subscriber location. The parsed data traffic is processed based on the profile of the plurality of profiles to produce processed data traffic, and transmitted from the packet queues over a downstream channel.
