Hardware-assisted HQoS is an alternative to traditional HQoS which is described in Scheduler QoS policies.
This model improves reaction time and provides more accurate control of downstream bursts for aggregate rate enforcement. It is based on:
hardware aggregate shapers (hw-agg-shaper)
additional hardware scheduling priorities (6 scheduling classes)
fair bandwidth distribution algorithm
software-based algorithm for enforcing HQoS at the vport level
