Abstract: According to certain embodiments, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise sending data from a hub to a spoke and receiving feedback from the spoke at the hub. The feedback is based on at least one of bandwidth utilization or occurrence of a congestion state detected by the spoke. The operations further comprise adjusting a shaper rate of an adaptive Quality of Service (QoS) shaper based at least in part on the feedback received from the spoke.
