Develop a simulation program to simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and-forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address, and frame destination address. The frames arrive at the switch in the order of which they appear in the input file. Destination address "X" indicate a broadcast frame. The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, Here is an example: "in.txt" contains 5 incoming frames: F1 P2 B--A F2 P6 D--C F3 P5 E--B F4 P7 F--D F5 P6 D--X "out.txt" should list the departing frames on each port: P1: F1 F2 F5 P2: F2 F3 F5 P3: F1 F2 F5 P4: F1 F2 F5 P5: F1 F2 F5 P6: F1 F4 F5 P7: F1 F2 F5 P8: F1 F2 F5
