Congestion based throttling in satellite based networks

摘要

A system and method for reducing waste of a network resource is disclosed. The method including: providing a group of active subscribers; determining an underutilization level of the network resource for an upcoming allocation interval; calculating a throttle and a resource weight for the group of active subscribers to decrease the underutilization level; allocating the network resource based on the throttle and the resource weight; and adjusting, based on a feedback underutilization level, the throttle and the resource weight. In some embodiments, the throttle is based on congestion metrics including measuring available channel capacity, a latency, a queue depth, a count of subscribers in an outroute channel or the like. In some embodiments, the active subscribers may include under subscribers, over subscribers and premium subscribers, wherein each of the over subscribers have exceeded a respective network resource usage allowance for a respective subscription interval.
