Cоnsider the figure belоw, in which а TCP sender (Hоst A) sends 8 TCP segments аt t = 1, 2, 3, 4, 5, 6, 7, аnd 8. Suppose the initial value of the sequence number is 0, and every segment sent to the receiver contains 10 bytes. The delay between the sender and the receiver is 5 time units, so the first segment arrives at the receiver (Host B) at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12, 13, 16 are shown. The TCP segments (if any) sent by the sender at t = 11, 14, 15, 17, 18, 21 are not shown. The segment sent at t=6 is lost, as are the ACK segments sent at t=7 and t=8. Go-Back-N a. (6 pts) When ACK at t=14 is received, will Host A send out any packets? Yes or No? ________If yes, how many packets will be sent, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________ If No, why not? b. (6 pts) When ACK at t=15 is received, will Host A send out any packets? Yes or No? ________ If yes, how many packets will be sent, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________ If No, why not? c. (6 pts) When ACK at t=17 is received, will Host A send out any packets? Yes or No? ________ If yes, how many packets will be sent, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________ If No, why not?
