MO-VNFCP

A multi-objective heuristic for VNF chain placement.

This repository contains the sources used for the work published in:

S. Lange, A. Grigorjew, T. Zinner, P. Tran-Gia, and M. Jarschel, “A multi-objective heuristic for the optimization of virtual network function chain placement,” in Proceedings of the 29th International Teletraffic Congress (ITC), Genoa, Italy, 2017.

Dependencies and Compatibility

The project was initially compiled and tested with Oracle Java Version 9. Some functions require the JavaFX Runtime, which should be included in Oracle JDK bundles, but may need a separate installation if only a Java Runtime Environment was installed.

The latest version of this project was also tested with OpenJDK 11 and OpenJFX 11.

Execution

You can either load the source code in a Java IDE of your choice and run the respective classes directly, or simply run the jar file contained in the artifacts folder. Its first execution should create a default config file config.js in your current working directory.

If you are using OpenJDK with the open source JavaFX implementation, you may need to add the OpenJFX libraries to your module dependencies. In addition, executing classes other than Main may require the following Java VM arguments:

--module-path <PATH TO YOUR OPENJFX LIBS> --add-modules=javafx.controls --add-exports=javafx.graphics/com.sun.javafx.util=ALL-UNNAMED --add-exports=javafx.base/com.sun.javafx.reflect=ALL-UNNAMED --add-exports=javafx.base/com.sun.javafx.beans=ALL-UNNAMED --add-exports=javafx.graphics/com.sun.glass.utils=ALL-UNNAMED --add-exports=javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED

Executing Main requires a valid path to a config file as first program argument. Using the configuration from res/config.js should run a quick optimization and directly display its results in the graphical user interface.

Adjust the default configuration to your needs, for example:

  • Set the basePath to a valid problem instance, for example contained in java/VNFP/res/problem_instances/internet2.
  • Adjust the runtime for faster testing.
  • Set showGui to true to visualize the end results.
You can’t perform that action at this time.
