Given that two hosts A and Buse a selective-repeat protocol with a sliding-window of size 4 packets and a 3-bit sequence number. Suppose that host A has transmitted 6 packets to host B and that the third packet was lost in transit. Answer the following questions about the diagram. At event A, the following actions will take place Host A Host B pkt0 sent 01 2 34 56 pktl sent 0123456789 pkt0 revd, delivered, ACKO sent 0 1 2 3 4 56 pktl revd, delivered, ACKi sent pkt2 sent 0 1 2 3 4 5 6789(s) : 012 3 4 56789 Loss) pkt3 sent, window full 0 1 2 3 4 5 6789 Event A Event B EventC EventF Event D pkt2 TIMEOUT Event E Pkt3 receved,buffered, ACK3 sent O PK3 received, discarded, ACK2 sent O PK3 received, discarded, ACK3 sent receiver window will move to begin at3
