WebThere are algorithms that violate this property, such as hierarchical schedulers. I’ll illustrate this through hierarchical packet-fair queueing. Here, the idea is to divide capacity between two classes, Left and Right, in some ratio. Then, we recursively divide capacity between flows within each class, such as a, b and c, d.
