If you are looking for an environment light, practical and efficient to simulate networks, this environment is the core.
Best of all is that if all goes well, it 's just save the configuration files (default quagga) and up to its routers.
With this system, you can train your skills with networks in an environment totally safe.
So we go to the "hands - on" and install the system. I made a "compiled" after reading the documentation in the official site -http://www.nrl.navy.mil/itd/ncs/products/core
The instructions will follow shortly after the video, but remember, I did this article in a Linux Kali (Debian), so if you'll do in other distribution there may be some variation. In the Fedora also worked perfectly.

CORE Network Emulator does have a Docker Service that I contributed and wrote an article about. The initial version that is in 4.8 is mostly broken but I have fixed and improved it. A pull request is on GitHub.
The service allows you to tag Docker Images with 'core' and then they appear as an option in the services settings. You must select the Docker image which starts the docker service in the container. You then select the container or containers that you want to run in that node. It scales quite well and I have had over 2000 nodes on my 16Gb machine.
You mentioned OVS as well. This is not yet built in to CORE but can be used manually. I just answered a question on the CORE mailing list on this. It gives a brief overview of switching out a standard CORE switch(bridge) with OVS. Text reproduced below if it is useful:

Note that the Linux RPM and Debian packages do not use the/usr/local prefix, and files are instead installed to /usr/sbin, and /usr/lib. This difference is a result of aligning with the directorystructure of Linux packaging systems and FreeBSD ports packaging.
Another note is that the Python distutils in Fedora Linux will install the COREPython modules to/usr/lib/python2.7/site-packages/core, instead ofusing thedist-packages directory.
The CORE Manual documentation is built separately from thedoc/ sub-directory in the source. It requires Sphinx:

If you are looking for an environment light, practical and efficient to simulate networks, this environment is the core.
Best of all is that if all goes well, it 's just save the configuration files (default quagga) and up to its routers.
With this system, you can train your skills with networks in an environment totally safe.
So we go to the "hands - on" and install the system. I made a "compiled" after reading the documentation in the official site -http://www.nrl.navy.mil/itd/ncs/products/core
The instructions will follow shortly after the video, but remember, I did this article in a Linux Kali (Debian), so if you'll do in other distribution there may be some variation. In the Fedora also worked perfectly.
