Linux-based CPE devices have AQM functionality integrated into the Wifi stack. The AQM itself operates at layer 3, but the Linux Wifi stack implementation uses information from layers 2 and 4 to improve scheduling decisions, eg. airtime-fairness and flow-isolation (FQ). This works best on soft-MAC Wifi hardware, such as ath9k/10k and MT76, where this information is most readily available to software. In principle it could also be implemented in the MAC, but I don't know of any vendor that's done that yet. - Jonathan Morton _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
