Runnning tests:

---

Single runs

1. Launch a delay shell
   $ mm-delay 50
2. The scripts for running the necessary tests are in Scripts/
   mm-delay 50 $ cd Scripts/
3. Launching the test
   mm-delay 50 $ ./launch.sh <target_URL>
4. Ending all processes (not necessary) mm-delay 50 $ ./clean.sh

Running tests with multiple trials per RTT (for cleaner results)

1. Launch a delay shell
   $ mm-delay 50
2. The scripts for running the necessary tests are in Scripts/
   mm-delay 50 $ cd Scripts/
3. Launching the test
   mm-delay 50 $ ./multi-launch.sh <target_URL> <number of trials per RTT>
   each trial's data will be stored in Gordon/Data/windows<trail_num>.csv
   cleaned data is stored in Gordon/Data/windows.csv
4. Ending all processes (not necessary) mm-delay 50 $ ./clean.sh

Analyzing the data

The final data at the end of either of the above tests are stored in windows.csv. The individual trials for 'multiple-trails-per-RTT' test type are stored as windows1.csv, windows2.csv, ... windowsn.csv for 'n' trials. Plot the results using gnuplot plot.plt --persist for multiple-trials tests.

For single trial tests, you can simply open a gnuplpot shell and plot as plot 'windows.csv' u 3:2 w lines
