WebTo illustrate this idea, consider Hierarchical Packet Fair Queueing (HPFQ) [10]. HPFQ ﬁrst apportions link capacity between classes, then recursively between sub classes be-longing to each class, all the way down to the leaf nodes. Figure3aprovides an example scheduling hierarchy, the numbers on the edges indicating the relative weights of child WebWe design Hierarchical Packet Fair Queueing (H-PFQ) algorithms to approximate H-GPS by using one-level variable-rate PFQ servers as basic building blocks. By computing the system virtual time and per packet virtual start / nish times in unit of bits instead of seconds, most of the PFQ algorithms in the literature can be properly de ned as variable-rate servers.

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.
