[Bloat] Really getting 1G out of ISP?

[Wheelock, Ian]

Just to pull this back into context – it may well be that one ISP happens to muck around like that – however, rented/leased CMs still make up the majority of DOCSIS devices, so it is very likely that DOCSIS AQM is enabled and operating on the majority of connected DOCSIS 3.1 devices.

Users that own their CMs are still paying for the internet access with the specific ISP, so would likely expect equivalent performance.



Entirely true, but for the ISP the matter of whether the subscriber is using a rented or self-owned modem is not entirely petty - it is the difference of a line item on the monthly bill.  I'm sure you can see how the perverse incentives arise with that.
