In Weighted Fair Queuing (WFQ) model, is the data always dequeued at a rate defined by the weight or is the proportion of bandwidth for each queue defined w.r.t. the weights of queues that are not empty?

Solution

The proportion of bandwidth for each queue is defined with respect to the weights of queues that are not empty. In this way the bandwidth is fully utilized. If only one queue is not empty this queue will use all the bandwidth until another queue gets a packet.
