This document provides a quick introduction to MidoNet, a networking virtualization software plugin for OpenStack Neutron. It first briefly discusses software-defined networking (SDN) and how it separates network control and forwarding planes. It then explains how OpenStack Neutron provides networking as a service. MidoNet uses a distributed controller architecture without single points of failure to provide scalable virtual networking for OpenStack deployments using commodity hardware and switches.
