You cannot really control uplink bandwidth. The packet has already arrived
before you can interfere. For TCP sessions you can do a certain amount of
trickery to give the impression of a lower speed link by speed limiting
on the other side of the router. ie

[THEM]--------------[Your Router]--*speed limit here*--[Your Host]

If it is UDP or icmp or other traffic that has no internal flow control
you can't do anything about it
