This is not a solution, just a tip to guide your research.
Traffic "shaping" usually applies to output. "Policing"[0] usually applies
to input. Since we often can't shape on the router transmitting data to
us, in such cases we instead have to police on the receiving end and rely
on the sender's TCP flow control to reduce rates to the point where
packets aren't lost. This doesn't work for UDP and ICMP and works poorly
for varying loads.
