Extend the program in the previous exercise to simulate a VLAN switch. Have the program begin by reading configuration information that specifies a set of hosts and a set of virtual LANs to which they should be attached. Create a file of frames that each specify the computer sending the frame (i.e., the port on the switch over which the frame arrives) and a destination address. Show how each frame is forwarded.
