Are there any good switches that have modern AQMs in them like fq_codel? Also, If a home router has a built-in switch, is the buffering controlled by the AQM, or do the switches have their own internal buffering that takes precedence? The scenario I am thinking of is two ports trying to feed data out of a single port on a switch.
