Now, we would like to run Voice over IP between two machines. We have to run QoS and tag voice packet's TOS field, otherwise, the voice quality is terrible if we transfer file and make voice call at the same time. I am not familiar with tc in Linux.

Bounded class: class that is not allowed to borrow from ancestor classes, regardless of the limit status of those classes. 2. Isolated class: class that does not allow non-descendant classes to borrow its unused bandwidth and that does not borrow bandwidth from other classes in turn How does HTB implement a 'bounded class'? I seem to see no constructs to be able to do this. The 'ceil' parameter allows us to implement a part of the 'isolated' definition above. By
