It all depends on what you want to do. Have you read my docs on www.docum.org
?? But you are on the right track.
I have some remarks. 1kbit rate is _very_ low. And 15k burst is not much for
5mbit rate. If you don't specify the burst or cburst paramter, tc will
calculate the most optimal setting for you.

I'm there if I'm at home (nick name staf).
