  • ns-3 App Store Launched

    We would like to announce the general availability of the ns-3 App Store. The app store will organize information about the availability of extensions to the main ns-3 releases, starting with the current ns-3.29 release. The main page has more information about getting started with the app store. The app store implementation is largely due to Abhijith Anilkumar’s 2017 Google Summer of Code project, with backend extensions to Bake build system by Ankit Deepak, and with thanks to the Cytoscape project for permitting the reuse of their framework. The app store concept and initial Bake implementation are due to Inria (thanks due to Mathieu Lacage, Daniel Camara, and Walid Dabbous).
