Detailed explanation-1: -Which queuing method provides user-defined traffic classes where each traffic class has a FIFO queue? Class-based weighted fair queuing (CBWFQ) provides support for user-defined traffic classes. Each traffic class then uses a first-in, first-out (FIFO) queue to forward data.
Detailed explanation-2: -Weighted Fair Queuing (WFQ) is an automated scheduling method that provides fair bandwidth allocation to all network traffic. WFQ applies priority, or weights, to identified traffic, classifies it into conversations or flows, and then determines how much bandwidth each flow is allowed relative to other flows.
Detailed explanation-3: -Congestion management. These tools use packet classification and marking to determine which queue to place the packets in. Congestion management tools include priority queuing, first-in, first-out and low-latency queuing.
