C. Now assume round robin service. Assume that packets $$1,2,3,6,11$$, and 12 are from A. Assuming FIFO service, indicate the time at which packets 2 through 12 each leave class 1 , and packets $$4,5,7,8,9$$, and 10 are from class 2 . Indicate the time at which the queue. For each packet, what is the delay between its arrival and the beginning packets 2 through 12 each leave the queue. For each packet, what is the delay of the slot in which it is transmitted? What is the average of this delay over all 12 between its arrival and its departure? What is the average delay over all 12 packets? packets? D. Now assume weighted fair queueing (WFQ) service. Assume that odd-numbered B. Now assume a priority service, and assume that odd-numbered packets are high packets are from class 1 , and even-numbered packets are from class 2 . Class 1 has a priority, and even-numbered packets are low priority. Indicate the time at which WFQ weight of 2 , while class 2 has a WFQ weight of 1 . Note that it may not be packets 2 through 12 each leave the queue. For each packet, what is the delay possible to achieve an idealized WFQ schedule as described in the text, so indicate between its arrival and the beginning of the slot in which it is transmitted? What is why you have chosen the particular packet to go into service at each time slot. For the average of this delay over all 12 packets? each packet what is the delay between its arrival and its departure? What is the average delay over all 12 packets?
