Each totaltraffic graph in the method section shows the server or the client with the above RTT and Window Size as incoming and outgoing traffic. The horizontal axis represents the time in seconds and the vertical axis represents the measured traffic in bytes. The graphs presents the increase of traffic once the experiments starts and ends. Case 3. In comparing the window size and RTT staying the same, the traffic decrease once the window size increase. In comparing RTT and the window size staying the same, the traffic increase once RTT increase. Case 4. I will now focus on the throughput between the 4KB and 250ms case and the 32KB and 50ms. I will test these throughput by adding a variance delay to reorder the packets. I added 75ms of a variance delay to both throughputs. The following is the totaltraffic graph of both.

However, you can also change the throughput by reordering the packets by adding a variance delay. As stated earlier, there is a large difference in average throughput between the 4KB and 250ms case and the 32KB and 50ms case. So, now it is time to answer the question “Why is there a large difference in average throughput between the 4KB and 250ms case and the 32KB and 50ms?” The hypothesis stated was larger window size caused a difference among the two. If you take a look at the TCP Throughput equation express earlier, you can tell no matter what the RTT value is, if you have a large window size, it would cause a large difference. If you also take a look at Figure 10 and Figure 12, you can see that there is a lot more traffic with the 32KB and 50ms case. So, in the end, my hypothesis was
