Consider again the figure for P21.
a. Assume a priority service, with packets 1,4, 5, 6, and 11 being highpriority packets. The remaining packets are low priority. Indicate the slots in which packets 2 through 12 each leave the queue.
b. Now suppose that round robin service is used, with packets 1,4, 5, 6, and 11 belonging to one class of traffic, and the remaining packets belonging to the second class of traffic. Indicate the slots in which packets 2 through 12 each leave the queue.
c. Now suppose that WFQ service is used , with packets 1,4,5,6, and 11 belonging to one class of traffic, and the remaining packets belonging to the second class of traffic. Class I has a WFQ weight of I, while class 2 has a WFQ weight of 2 (note that these weights are different than in the previous question) . Indicate the slots in which packets 2 through 12 each leave the queue. See also the caveat in the question above regarding WFQ service.
