Do the "experts on chegg actually read the questions--asking the same question for the fifth time: Suppose that the WFQ scheduling policy is applied to a buffer that supports three classes (of priority packets), and suppose the weights are 0.25, 0.5, and 0.75 for the three classes. Further suppose that each class has a large number of packets in the buffer. In what sequence might the three classes be served in order to achieve the WFQ weights.
