It allows the execution of real network functions, packaged as Docker containers, in emulated network topologies running locally on the developer's machine. The emulation platform also offers OpenStack-like APIs for each emulated PoP so that it can integrate with MANO solutions, like OSM. The core of the emulation platform is based on [Containernet](https://containernet.github.io). + +The emulation platform `vim-emu` is developed as part of OSM's DevOps MDG. + +--- +## Acknowledgments + +This software was originally developed by the [SONATA project](http://www.sonata-nfv.eu) and the [5GTANGO project](https://5gtango.eu/), funded by the European Commission under grant number 671517 and 761493 through the Horizon 2020 and 5G-PPP programs. + +## Cite this work + +If you use the emulation platform for your research and/or other publications, please cite the following paper to reference our work: + +* M.

The easiest way is the automated installation using the OSM installer. The bare-metal installation requires a freshly installed **Ubuntu 18.04 LTS** and is done by an Ansible playbook. Another option is to use a nested Docker environment to run the emulator inside a Docker container. + +### Automated OSM installation + +This installation option applies if you want to use vim-emu in combination with OSM. + +```sh +./install_osm.sh --vimemu +``` + +This command will install OSM as well as the emulator (as a Docker container) on a local machine. It is recommended to use a machine with Ubuntu 18.04 LTS. More details about this installation option can be found in the [OSM wiki](https://osm.etsi.org/wikipub/index.php/VIM_emulator). + +### Standalone installation + +#### Option 1: Bare-metal installation + +```sh +sudo apt-get install ansible git aptitude +``` + +##### Step 1.
