  annote = {In this excerpt, taken from one of Cisco's routing manuals, several common active queuueing techniques are presented. More specifically, the following queueing techniques are discussed: Weighted Fair Queueing (WFQ) and variants of WFQ, i.e. Flow-based WFQ (WFQ), Distributed WFQ (DWFQ), Class-based WFQ (CBWFQ), and Low Latency Queueing, Custom Queueing (CQ), and Priority Queueing(PQ). WFQ classifies traffic into different flows based on some characteristics, i.e. source and destination addresses, protocol. Each flow are given a weight which determines the transmit order of queued packets. There are several advantages to using WFQ, i.e., WFQ alleviates the round-trip delay variability, making TCP congestion control and slow start mechanisms more accurate, WFQ shares the bandwith fairly between the flows, while at the same time give low-volume traffic precendence over high-volume traffic. The "normal" version of WFQ is also called Flow-based WFQ. DWFQ differs from WFQ in that you have several output queues, not just one. In CBWFQ, you define traffic classes based on match criteria including protocols, input interfaces etc. Packets satisfying the match criteria for a class constitute the traffic for that class. A queue is reserved for each class. LLQ brings strict priority queueing to CBWFQ, i.e. making it possible for delay-sensitive data such as voice to be dequeued and sent first. In CQ, you specify a certain number of bytes to forward from a queue each time the queue is serviced. The queues are serviced in a round-robin fashion. Finally, PQ makes it possible to give some types of flows absolute priority over others.},
