Find correct ones and explain briefly.

1.While holding the TCP window size the same, the larger the RTT value, the higher the Throughput.

2.While holding the TCP window size the same, the larger the RTT value, the lower the Throughput.

3.While holding the RTT value the same, the larger the TCP window size, the higher the Throughput.

4.While holding the RTT value the same, the larger the TCP window size, the lower the Throughput.

Why? (Justify your selections above using your own words.)

Explanation / Answer

The formula for the throughput is as follows:

Window size * 8 / RTT

so option 2 is correct as if we keep the value of window size as constant then the value of RTT must be lowered to increase the throughput as it is inversaly propotional to RTT
