What’s ns-3?

ns-3 is a network simulator for internet systems. It became popular beyond education and research through Google’s Summer of Code 2019.

ns-3 is build in Python and C++. Here are the main simulator phases which you have to specify:

  1. Define the network topology.
  2. Develop your models (e.g. UDP, TCP).
  3. Configure the nodes and links.
  4. Simulate network events.
  5. Analyze performance of the simulation.
  6. Visualize the results using plotting libraries.
