Assume you are using the Go-Back-N protocol with a window size of 5 slots, sequence numbers ranging [0,20] and that the sender side application has at least 20 packets worth of data ready to send to the transport layer. Consider now that the sender has sent out a full window of packets, with sequence numbers 0 thru 4 . If the sender receives the following ACKs: ACK0, ACK1, ACK2, ACK2, ACK2, ACK2, ACK2, and then a time out occurs, which packets does the sender retransmit? Packets 0 thru 4 Packets 3 and 4 Packet 3 Packets 3 thru 7
