Question

Three packets of size 3, 2 and 1 for connections A, B and C arrive at an empty queue (time slot 0) with a service rate of 1:

(a) Show the start and finish time for each packet being served by the queue (idealistic generalized processor sharing)

(b) Show the real time interval for each packet being served by the queue (fair queuing to mimic generalized processor sharing)

(c) Show the real time interval for each packet being served by the queue (fair queuing) if three more packets of size 1, 1 and 1 for connections A, B and C arrive at time slot 1

Explanation / Answer

link propagation delay = T1 = 10 km / (2
