There is nothing stopping this, and it's being worked on (PIE goes into DOCSIS 3.1). http://www.cablelabs.com/wp-content/uploads/2014/06/DOCSIS-AQM_May2014.pdf https://www.nanog.org/sites/default/files/20160922_Klatsky_First_Steps_In_v1.pdf Cable Labs (as far as I understand) is an organisation funded by cable operators and vendors, and they create standards and tests used by the cable industry. I don't know what tests Cable Labs perform, but there is nothing stopping them from validating buffers+AQM in the modems as well, and I do hope they do this going forward. Why not reach out to Greg White who is mentioned in the cablelabs DOCSIS-AQM pdf above and ask? Or even better, invite him to this list if he's not already here. He's on the IETF AQM WG list, I have posts by him in my folder back to 2013. -- Mikael Abrahamsson email: swmike@swm.pp.se
