Problem 1: Consider the discussion in Section 1.3 of our textbook about statistical multiplexing in which an example is provided with a 1 Mbps link. Users are generating data at a rate of 100 kbps when busy, but are busy generating data only with probability p = 0.1. Suppose that the 1 Mbps link is replaced by a 1 Gbps link. a. What is N, the maximum number of users that can be supported simultaneously under circuit switching? b. Now consider packet switching and a user population of Musers. Give a formula in terms of p, M, N) for the probability that more than N users are sending data
