An output interface in a switch is designed using the leaky bucket algorithm to send 8000 bytes/s (tick). If the following frames are received in sequence, show the frames that are sent during each second.
? Frames 1, 2, 3, 4: 4000 bytes each
? Frames 5, 6, 7: 3200 bytes each
? Frames 8, 9: 400 bytes each
? Frames 10, 11, 12: 2000 bytes each
