P4. Consider the circuit-switched network in Figure 1.13. Recall that there are 4 circuits on each link. Label the four switches A, B, C, and D, going in the clockwise direction. What is the maximum number of simultaneous connections that can be in progress at any one time in this network? Suppose that all connections are between switches A and C. What is the maximum number of simultaneous connections that can be in progress? Suppose we want to make four connections between switches A and C, and another four connections between switches B and D. Can we route these calls through the four links to accommodate all eight -connections?
