a. (5 points) What is the key difference between virtual circuit and circuit switching? (one or two sentences should suffice!) b. (10 points) Consider the network shown in Figure 2, where the numbers beside the links connecting hosts and routers represents the port numbers of the routers. Please write down the virtual circuit translation tables for all the routers after the following connections are established in the order given below. You can assume that the VCI assignment always picks the lowest unused VCI on an outgoing link. (1) Host A connects to host K. a.
