Question 1: (1 Mark) Consider the circuit-switched network shown in the figure below, with circuit switches A, B, C, and D. Suppose there are 15 circuits between A and B,19 circuits between B and C,20 circuits between C and D, and 14 circuits between D and A. Note: Please write all the steps of the answer, Direct answers will get partial credits. What is the maximum number of connections that can be ongoing in the network at any one time? Suppose that every connection requires 2 consecutive hops, and calls are connected clockwise. For example, a connection can go from A to C, from B to D, from C to A, and from D to B. With these constraints, what is the is the maximum number of connections that can be ongoing in the network at any one time? Note: Please write all the steps of the answer, Direct answers will get partial credits
