про Consider a 4x2 switching element. Time is slotted. The independent arrival probability of a packet in a slot at each of the four inputs at the left is p. If there is one input packet in a slot it goes to either output. If there are two or more arrivals to the inputs, two packets go to the outputs (one on each output) and any remaining packets are dropped or erased. (a) Write an expression for 3 or 4 arriving packets in a slot. P (b) Write an expression for the average thruput* of packets at the output. 4x2 s.e, [c] Is the thruput at the input and the output the same? If not, which is greater and why? *Thruput at output =1Prob(1 arrival)+2Prob (2 arrivals)+2Prob(3 or 4 arrivals) outputs про Consider a 4x2 switching element. Time is slotted.
