Have you looked at existing network simulators?

On two different ends of the spectrum are:

  Switchyard, a small network simulator intended for pedagogy
  https://github.com/jsommers/switchyard

  NS-3, the researcher's toolkit
  https://www.nsnam.org/
  https://www.nsnam.org/wiki/Python_bindings

Good luck,
