A host uses TCP to send a file of size

$100$

$$kbytes$.$

All segments during this transmission have size

$1000$

$$bytes

$($

not including the TCP and

IP headers

$)$

$.$

$$It would take

$100$

$$segments to send the entire file if there were no losses.

Due to congestion, the

$2$

nd

$,$

$50$

th and

$98$

th segments sent by the sender are lost. No

other packets are lost. Note that due to retransmission, for example, the

$50$

th segment

is not the

$50$

th segment of the file.

Plot the congestion window

$$as a function of time for TCP Tahoe.
