OT somewhat and on my beta noir, sorry!

I am curious as to what if any, higher end products rfc8290 has
appeared in already? It's got to be quite a lot over the past year,
particularly on qualcomm and mediatek's wifi chips. I know of preseem
and libreQos in middleboxes... a couple I can't talk about unless I
find public info on it...

https://en.wikipedia.org/wiki/FQ-CoDel

Comcast rolled out DOCSIS-pie this year also. Really compelling
real-world study across a million boxes here:

https://arxiv.org/abs/2107.13968

Very pretty graphs starting pp14.

Anyway it's looking like pie and fq_codel are winners (unlike RED).

but I'd totally settle for that BCP recommending some form of aqm be
available in your document at the two points so far. A deeply
philosophical discussion of what constitutes a host could however
ensue.
