Most of the example programs in ns-3 have a topology diagram in the code (as comments) that makes the user visualize the topology for which the program is written. This task is about adding such a topology diagram for ‘examples/tcp/tcp-variants-comparison.cc’.

The student is expected to do the following:

1. Analyze the source code of ‘examples/tcp/tcp-variants-comparison.cc’ (looking at the main function is sufficient).
2. Prepare a rough draft of the topology diagram and verify it with the code.
3. Draw the topology diagram as ASCII art in the comments in the source code.
4. Submit the patch for evaluation.
