Consider the figure below in which a TCP sender and receiver communicate over a connection in which the sender->receiver segments may be lost. The TCP sender sends an initial window of 5 segments. Suppose the initial value of the sender->receiver sequence number is 362 and the first 5 segments each contain 638 bytes. The delay between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t=8. As shown in the figure below, 3 of the 5 segment(s) are lost between the segment and receiver.

QUESTION 2 OF 2
Give the ACK numbers the receiver sends in response to each of the segments. If a segment
never arrives use 'x' to denote it, and format your answer as: a,b,c,...
t = 8
t = 9
