Mininet is a lightweight container orchestration system that is specialized for network emulation. With Mininet and onos.py, you can easily start up an ONOS cluster, and a modeled data network for any topology you might like, in a single VM or server. This is usually the most convenient way to create an ONOS development environment on your laptop, and you can be up and running in a matter of minutes (or seconds if you have already built ONOS and have already installed Mininet!)
