Suppose host A has 10 packets with sequence numbers 1 to 10 to be transmitted to host B. Now imagine that the packets numbered 2 and 7 are lost when they were sent the first time. Assume that ACKs are never lost. How many total packets (including retransmissions) are sent with stop-and-wait. Answer the same for go-back-n assuming windows of size 3 (at most 3 outstanding, unacknowledged packets). -justify your answer.
