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 Web1 de jul. de 2014 · In most systems, fair-queueing packet schedulers are the algorithms of choice for providing bandwidth and delay guarantees. These guarantees are computed assuming that the scheduler is directly attached to the transmit unit with no interposed buffering, and, for timestamp-based schedulers, that the exact number of bits transmitted …
