Dear reader, I'm not updating these pages anymore. If you have tc or ip related questions, you can post them on the LARTC mailing list.

What I wanna do

I want to know how accurate CBQ can split the bandwidth in 2 differnt classes. You can do it on 2 different ways: you provide no weight parameter and uses the rates or you can provide a weight parameter. You also have the possibility to use an extra qdisc connected to a bounded class.



If you want to split the traffic in different classes so the classes can borrow traffic from each other, create a bounded class with the total bandwidth, attach a qdisc to it and attach the classes who may share the bandwidth to this qdisc.

The qdisc attached to the bounded class will prevent that the other classes can get more bandwith then they may get.


I made this overview from all the splitting-tests. For more explanation, visit the two splitting pages and read the conclusions.
