FWIW, on the narrow knowing variable rate point, in the UK DSLAMs use (I
think) TR101 to report sync rates to ISPs.
It has always been the case that BRAS is set with this, my ISP does also
use it to do downstream (for me, egress for them) QOS.
Of course they need (expensive?) kit to mark, and DPI/rules to classify
traffic ....
They use Ellacoyas. I don't know if they do the actual shaping or just
the classification and marking.
