Preface
The OpenStack Networking service (codename neutron) is the software-defined networking component of Red Hat OpenStack Platform 15.
Software-defined networking (SDN)
Network administrators can use software-defined networking (SDN) to manage network services through abstraction of lower-level functionality. While server workloads have been migrated into virtual environments, they are still just servers that look for a network connection to send and receive data. SDN meets this need by moving networking equipment (such as routers and switches) into the same virtualized space. If you are already familiar with basic networking concepts, then it is easy to consider that these physical networking concepts have now been virtualized, just like the servers that they connect.
