Consider the circuit-switched network in the Figure below. 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?
