What is piggybacked ACK

The protocol will be incorrect. Suppose that 3-bit sequence numbers we are using. Consider following situation:

A just send frame 7.

B gets frame and sends a piggybacked ACK.

A gets ACK and sends frames 0-6, all of that get lost.

B times out and again transmits its current frame, with ACK 7.

Look at the situation at A when frame with r.ack = 7 arrive. The key variables are AckExpected = 0, r.ack = 7, and Next Frame to Send = 7. The modified among will return true, causing A to think lost frames were being acknowledged.
