WebFeature Overview. Class-based weighted fair queueing (CBWFQ) extends the standard WFQ functionality to provide support for user-defined traffic classes. For CBWFQ, you define traffic classes based on match criteria including protocols, access control lists (ACLs), and input interfaces. Packets satisfying the match criteria for a class ... 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
