Hi, for something like that to work, you need a lot of programming and testing in different situations. Sharing traffic shaping across different boxes can become very complicated if you want to do it right, I don't think you can find experts willing to program and test everything, setup test networks etc. for 300$. Good luck, Jeroen. On Mon, 12 Apr 2004 17:49:00 -0400 (EDT) alex@xxxxxxxxxxxx wrote: > Currently, linux tc has very useful concept of a 'index' for a given > policy.
