The modern AQM's are based on "Time in Queue". Both pie and codel work brilliantly with pause frames, so long as BQL is also in the driver. fq+aqm (be it codel, pie or cobalt) works even better. See: https://datatracker.ietf.org/doc/html/rfc8290 https://datatracker.ietf.org/doc/html/rfc8290 https://datatracker.ietf.org/group/aqm/documents/ https://datatracker.ietf.org/group/aqm/documents/ https://arxiv.org/abs/1804.07617 https://arxiv.org/abs/1804.07617 Adding AQM and FQ wifi was way, way harder, (apenwarr drove the group at google that did some of it), but there is full support for fq_codel now in the mt76, ath9k, ath10k, iwl, and one new realtek chipset in the linux kernel. https://lwn.net/Articles/705884/ https://lwn.net/Articles/705884/
