WebA network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication network.

WebModified schedulers preserve guarantees close to the original ones, and can also handle seamlessly both leaves and internal nodes in a hierarchical setting. We also present Quick Fair Queueing Plus (QFQ+), a fast fair-queueing scheduler that we defined using this scheme, and that is now in mainline Linux. 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.
