8. To increase the speed and reliability of the five-stage Clos network C8,2,3 using C2,3 we form three multiplexed parallel planes, each of which contains this network. (a) Sketch the overview of the network. (b) Show a Lee's model. (c) Assuming the probability that any link in the networks including multiplexing links is busy is p = 0.2, find the total blocking probability for the network. 8.
