Assume we want to change the Stop-and-Wait protocol and add the NAK (negative ACK) packet to the system. When a corrupted packet arrives at the receiver, the receiver discards the packet, but sends a NAK with a nakNo defining the seqNo of the corrupted packet. In this way, the sender can resend the corrupted packet without waiting for the time-out. Explain what changes need to be made in the FSM of Figure 23.21 and show an example of the operation of the new protocol with a time-line diagram.
