After the semester finished I finally found some time to publish the 3D STP Simulator that I’ve developed for my Diploma Thesis.

The Python application features a GTK GUI (wxPython) to build and control a custom network topology and a VPython frontend to visualize virtual switches and network cables in a 3D environment.

The program still is a proof of concept. If you intend to try it out, I’d be happy to get feedback and bug reports. Please make sure to use wxPython version 2.8 or higher as there is a problem with the spinbox callback of older implementations.

If you are interested in Ethernet switching algorithms – especially in the industrial field – you can also take a look at the Diploma Thesis (German, PDF, 10 MByte) itself. Again I’d like to hear your feedback.
