Suppose that the selective repeat protocol is used. The sequence number space is {0,1,2,3}. Assume that the sender window size is N=3. At the start, the sender sends packets with sequence numbers in 0,1, and 2, respectively. The receiver receives these packets and sends ACK 0, ACK 1, and ACK 2, respectively. However, these three ACK messages are lost.
