GNPyWrapper

Introduction

The goal of the GNPyWrapper.jl is to increase the programmabilty of the already existing GNPy Package (github page, pip page).

It is mainly written in Julia because this language has some advantages. For example code execution speed.

The work was inspired by the gnpy-transmission-example provided by the developers of GNPy.

The idea of the GNPyWrapper.jl is to only use the core functionalities of the GNPy Package. This is done by:

• Getting rid of:

  • the automatic initialization step of the provided gnpy-transmission-example

  • and thereby getting rid of json data format and merging process

• Providing:

  • network element example descriptions in "native" Julia language

    • which were created from gnpy-transmission-example with json-data

  • from which you can generate gnpy objects and vice versa

  • a automatic process from which you can generate element and path descriptions

  • two examples

    1. "example_01.jl"
    2. "example_02.jl"

Advantages

• interface from Julia to Python for GNPy Package and vice versa

• full control over gnpy elements

• also, better "understanding" of what is going on in the core of GNPy

Disadvantages

right now:

• less automation

Installation and Initialization of GNPyWrapper.jl

1. git clone this repo

2. run julia

3. activate the GNPyWrapper.jl

4. activate/install julia specifc packages

   1. CondaPkg

      using CondaPkg

      ]conda add python

   2. PythonCall

      using PythonCall

5. install GNPy from pip

   ]conda pip_add gnpy==2.8.0

Examples

First example

• Set up:

  • you need to copy cli_example_02.py and paste it in the correct folder of GNPy (gnpy.core.tools) next to cli_example
    • the cli_example_02.py can be found in GNPyWrapper.jl\test\gnpy_transmission_example_script
    • the folder is located in the \GNPyWrapper.jl.CondaPkg\env\Lib\site-packages\gnpy\tools

• From Julia in the GNPyWrapper.jl\test folder run:

  include("example_01.jl")

Second example

• Set up:

  • you need to copy cli_example_02.py and paste it in the correct folder of GNPy (gnpy.core.tools) next to cli_example
    • the cli_example_02.py can be found in GNPyWrapper.jl\test\gnpy_transmission_example_script
    • the folder is located in the \GNPyWrapper.jl.CondaPkg\env\Lib\site-packages\gnpy\tools

• From Julia in GNPyWrapper.jl\test folder run:

  include("example_02.jl")
