Traffic Shaping

Erich Schubert blogs about traffic shaping, and shows how you can do some basic traffic shaping using a rather long example. I'm sure that example works, but mine is slightly less complex:

This is actually a literal example in the Linux Advanced Router and Traffic Control-HOWTO, and it works for me. Linux has a reasonably good default prioritizing and queueing already, and using the tbf filter doesn't replace them, whereas the detailed sfq example that Erich gave does. I'm doing this on my router (on the outgoing interface), not my laptop, which is also a rather important bit.

Of course, it working for me doesn't necessarily mean that it'll work for you too. But you might just want to try it...
