Ok. Then class 1:200 may "borrow" from 1:100 via the path to root class. > > If there's more than one child borrowing from the same class, they're > served according to their priority (argument prio in *tc class add*). > > If there's more than one child having the same priority, then they're > served in DRR order (Deficit Round Robin). So will the available BW at root class be assigned to 200 and 100 proportionally to its rate (different amounts) or they both (100 and 200) grow by the same amount up to its own ceil?
