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 ...

Hierarchical fair queueing: A credit-based approach for hierarchical ...

Web28 de ago. de 1996 · Hierarchical Packet Fair Queueing (H-PFQ) algorithms have the potential to simultaneously support guaranteed real-time service, rate-adaptive best-effort, and controlled link-sharing service. In this paper, we design practical H-PFQ algorithms by using one-level Packet Fair Queueing (PFQ) servers as basic building blocks, and … 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. in clinic lateral flow test near me https://peruchcidadania.com
