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. WebTo illustrate a scheduling tree, consider Hierarchical Packet Fair Queueing (HPFQ) [13]. HPFQ ﬁrst divides link capacity between classes, then recursively between sub classes in each class, all the way down to the leaf nodes. Figure 2a provides an example; the number on each child indicates its weight relative to its siblings. HPFQ cannot
