Question

Suppose users share a 3 Mbps link through circuit switching. Also suppose each user requires 150 kbps when transmitting, but each user transmits only 10 percent of the time.

a) How many users can be supported?

b) Find the probability that a given user is transmitting.

c) Suppose there are 120 users. Find the probability that at any given time, exactly n users are transmitting simultaneously.

d) Find the probability that this circuit-switching link cannot transmit data from the users (probability of failure)
