You can however, solve this assignment in a VM. | + | Do not try to do this in **wsl**. Its kernel implements network namespaces very poorly and you will have disastrous results.

| Try varying the bandwidths and delays of the **h1-r1** and **h2-r1** links. Best if you keep them symmetric. Record the same metrics that you've used in your previous experiment. | Try varying the bandwidths and delays of the **h1-r1** and **h2-r1** links. Best if you keep them symmetric.

| - | Create two figures, one for the bandwidth-varying experiment, and one for the delay-varying experiment. Create multiple plots for these experiments within the same figure and explain what impact these variations had. Just to clarify, for the "throughput as a function of time" figure, plot each experiment where you vary the delay with **±k * 25ms** (with k = 0, 1, 2, 3, ...) and label them accordingly. Aim for something like [[https://stackoverflow.com/questions/22276066/how-to-plot-multiple-functions-on-the-same-figure|this]]. | + | Create two figures, one for the bandwidth-varying experiment, and one for the delay-varying experiment.

| + | If you decide to write the report in LaTeX, try [[https://github.com/tectonic-typesetting/tectonic|tectonic]]. It's much leaner than **pdflatex** and will automatically install the packages included in your source files. **tectonic** packages should be available on most distributions.
