Hi Neal,

As far as I can tell the PIE aqm is mandatory in all DOCSIS 3.1 CPEs, do Al you need is a modem certified for 3.1 and probably also an DOCSIS ISP supplying 3.1 services (I assume the AQM will only be engaged in a docsis 3.1 environment), as in DOCSIS the ISP basically has control over the CPE, so you would need their cooperation. Not every DOCSIS ISP will provision any customer modem, but I assume you have enough leverage to make this happen.

Anyway according to the spec sheets:
AVM Fritzbox 6591
Netgear CM1000-1AZNAS
Arris SB8200
Motorola MB8600
should give you what you want.

Best Reards

P.S.: I would love to hear your results, as information about the effects of docsis pie in the wild is quite limited...

Anyone have a pointer to a cable modem model that is available for purchase and implements the DOCSIS 3.1 PIE mechanism?  (So far, my searches for this have only found other people asking this question, rather than the answer. Apologies if I missed something that should be easy to find.)

I'm curious to have one for testing with BBR v2. I'm aware of the Linux PIE implementation, but it would be nice to have the actual cable modem version to play with as well.

Thanks!
