The problem with low prio (and so higher priority classes) happens when you overlimit the class (sending more data then the rate of the class). If you overlimit it, the latency can be very high. > > For the quantum problem, see the faq pages on www.docum.org > > I read your FAQ before, and I'm sure I still don't understand > it fully.

You need to take r2q so for the lowest rate, rate / r2q > 1500 and for the highest rate, rate / r2q < 60000. This is only for leaf classes (class with no child class). If you don't find a r2q that can do this, you have to choose the best r2q and overrule the quantum for the classes where the rules are not satisfied You can ignore the quantum errors, but it's better to make sure they you don't get them.
