Host A sends 6 packets to Host B using TCP protocl with each packet10 bytes long, and starts with sequence number 90. We assume the third packet is lost and there is no delayed ACK, but all the six packets arrive at Host B finally. How many ACKs does Host B sends back to Host A (5 points)? What is the acknowledgement number for each ACK packet from Host B to Host A (15 points)? (Result: 5 points, Proof: 10 points) (Proof is needed)
