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$$sequence number is $229$ and the first $5$ segments each contain $422$ bytes. The delay$$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.
