That's the only thing available to me on the platforms I have. If you
would like this improved, please reach out to the Cisco ASR9k BU and tell
them to implement ECN and PIE (or something even better). They won't do it
because I say so, it seems. WRED is all they give me.
This is a whole different discussion but if you want to have a per-user context
at the BNG level + TM + FQ I'm not sure that kind of beast will ever exist.
Unless you have a very small user fan-out the hardware clocks could loop over
several thousands of contexts.
You should expect those kind of features to be in the CMTS or OLT.

Sorry, I only transport the packets, I don't create them.
I'm sure you create a lot of packets. Don't be humble.

If i have lots of queue I might instead get customer complaints about high
latency for their interactive applications.
