Apparatus and method for a bandwidth allocation approach in a shared bandwidth communications system

摘要

An approach is provided for delivering high throughput inroute bandwidth to a terminal in a shared bandwidth satellite communications system. A backlog level of each of a number of remote terminals is monitored, wherein the backlog level of each terminal reflects an amount of data traffic awaiting transmission via an inroute channel of the communications system. When it is determined that the backlog level of one terminal meets a first threshold level, the terminal is assigned to an express priority bandwidth allocation stage. The backlog level of the terminal is monitored while assigned to the express priority stage. When it is determined that the backlog level of the terminal has fallen below a second threshold level, the terminal is removed from the express priority stage. Further, a probability is applied to a qualifying terminal, where the probability controls whether the terminal is assigned to the express priority bandwidth stage.
