This illustration repeats the structure of figure 3.31, which depicts an interaction between Host A and Host B. The interaction begins at the topmost portion of Host A's timeline. A blue arrow, labeled "Seq=92, 8 bytes data," extends diagonally downward to the right and intersects with Host B's timeline. An arrow, labeled "ACK=100," extends from Host B's timeline halfway back to Host A's timeline and terminates, indicating a loss. Host A resends the initial transmission, and the area of Host A's timeline between the first transmission and the second is labeled "Timeout." Host B responds to Host A's transmission with an arrow labeled "ACK=100."
