A host sends five packets and receives three acknowledgments. The time is shown as hour:minute:seconds.

a. Segment 1 was sent at 0:0:00.

b. Segment 2 was sent at 0:0:05.

c. ACK for segments 1 and 2 received at 0:0:07.

d. Segment 3 was sent at 0:0:20.

e. Segment 4 was sent at 0:0:22.

f. Segment 5 was sent at 0:0:27.

g. ACK for segments 1 and 2 received at 0:0:45.

h. ACK for segment 3 received at 0:0:65.

Calculate the values of RTTM, RTTS, RTTD, and RTO if the original RTO is 6 seconds. Did the sender miss the retransmission of any segment? Show which segments should have been retransmitted and when. Rewrite the events including the retransmission time.
