Terrestrial mobile networks still haven’t implemented fq and aqm technologies.

Link?

At 250+ms most our protocols start sending more packets, compounding this problem.

Admittedly an outage of this size is probably not something that can be handled with pure fq+aqm, as it would basically look more like a syn flood attack!

I don’t think data caps are needed. fairness is needed.

I would prefer a solution that just billed for usage over a minimum.
