There are many user-facing changes in this release. We've changed the way how examples and default data are shipped:

  • examples/transmission_main_example.py is replaced by gnpy-transmission-example
  • examples/path_requests_run.py is replaced by gnpy-path-request
  • Default example data, such as the equipment library, the CORONET sample topology, etc, are now shipped as a part of the Python library. You can request their location by running gnpy-example-data.
  • There's a new tool for converting XLS data into JSON: gnpy-convert-xls.

The installation process got much easier, it should be enough to just run pip install gnpy once you've installed your Python 3.6 (or newer).

For those who use GNPy as a Python library, there were many changes as we have moved different parts of code to better places. We no longer put everything into the gnpy.core.* Python module hierarchy, now there is:

  • gnpy.core which implements signal propagation,
  • gnpy.topology tracks requests for spectrum,
  • gnpy.tools provides miscellaneous tools for, e.g., dealing with JSON I/O, XLS parsing, as well as the example frontends.

GNPy now also tracks chromatic dispersion (CD) and polarization mode dispersion (PMD) of a signal as it propagates through fiber and all active nodes.

Under the hood, we've adjusted our development process a bit. We are using Gerrit (via GerritHub.io) for code review, and Zuul (via VexxHost) for Continuous Integration (CI).
