If you intend to use the ns-3 simulation libraries to explore the behavior of existing models by writing new simulation scripts in C++ or python, the following sections attempt to answer common questions that we see regularly on our mailing-lists. If you have questions that are not answered here, consider looking at our fairly extensive documentation or asking your question on our ns-3-users mailing-list.
