 \subsection{Bandwidth Variation}
 
-This criteria judges the adaptability of the congestion control system in changing network conditions. To test this, the bandwidth of one of the local portal's connections is varied during an iperf3 throughput test. Thus far, bar graphs have been sufficient to show the results of each test. In this case, as the performance should now be time sensitive, I will be presenting a line graph. The error bars on the x-axis represent the range of continuous time results included in each discrete plotted point, while the y-axis error bars again represent the inter-quartile range of the gathered data. The target rates will be plotted as a fixed line for each of the speeds, as opposed to time-series. The error bar for these series will be omitted, as they occlude much of the graph, and are visible in Figure (ref needed).

+This criteria judges the adaptability of the congestion control system in changing network conditions. To test this, the bandwidth of one of the local portal's connections is varied during an iperf3 throughput test. Thus far, bar graphs have been sufficient to show the results of each test. In this case, as the performance should now be time sensitive, I will be presenting a line graph. Due to the nature of the time in these tests, producing consistent enough results to produce error bars was not feasible. The data is also smoothed across the x-axis with a 5-point moving average, to avoid intense fluctuations caused by the interface rate limiting.
 
 The criteria will be met if the following are true: the throughput begins at the rate of a time constant connection; the throughput stabilises at the altered rate after alteration; the throughput returns to the original rate after the rate is reset.

-Two graphs are presented here. Figure \ref{fig:bandwidth-variation-down} presents a situation where the speed of a connection decreases, before returning to its original rate. This test begins with two 2MBps connections, changing to 1MBps + 2MBps at $t=10$, and returning to two 2MBps connections at $t=20$. Figure \ref{fig:bandwidth-variation-up} presents a situation where the speed of a connection increases, before returning to its original rate. This test begins with two 2MBps connections, changing to 3MBps + 2MBps at $t=10$, and returning to two 2MBps connections at $t=20$.
+The results are given in Figure \ref{fig:capacity-changes}. The decreasing series drops from 2+2MB/s connections, with a maximum throughput of 32Mbps, to 1+2MB/s connections, with a maximum throughput of 24Mbps. The increasing series increases from 1+1MB/s connections, with a maximum throughput of 15Mbps, to 1+2MB/s connections, with a maximum throughput of 24Mbps. The events occur at approximately the same time. The graph displays each series beginning at their constant amount, before converging at approximately 24Mbps in the center of the graph. Once the connection change is reversed, each series returns to its original throughput. This satisfies the success criteria for connection capacity changes.
