If you bound a class, the class can never send more then the configure rate. So that's the ceil. If you add a sub class (not bounded), that class has to respect the rate (in this case also the ceil) of it's parente. > > One of the reasons why I like htb is you don't need > > these confusing options. > > And htb don't rely on the nic hardware to calculate > > the actual rate. > hmm, that's true.
