My mistake. Each class will get bandwidth proportional to the rate untill all the rates are satisfied or there is no bandwidth left. Remaining bandwidth is given to the class with the lowest priority and proportional to the quantum parameter. One of the rules if you create a htb setup, is to make the sum of the rates of the child classes <= rate of the parent class. So the rate can always be satisfied. You don't have to follow this rule, htb will work fine, but it will no be obviously to know what's going on.
