TCP sequence and ACK numbers. Consider the figure below, where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8. Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKS sent by the receiver at t = 6, 7, 8, 10, 11, 12 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown. The segment sent at t=4 is lost, as is the ACK segment sent at t=7. TCP sender t=1 t=2 t=3 t=4 t=5+ t=6+ t=11 t=12 t=13 t=14 t=15 t=16 t=17 t=18 1 / 1 1 1 data segment data segment data segment data segment data segment data segment data segment data segment ACK ACK ACK ACK ACK ACK I I VY II I I 1 V \/\/ \/ 1 TCP receiver t=6 t=7 t=8 t=9 t=10 t=11 t=12 t=13 What is the sequence number of the segment sent at t=2?
