- Northbound APIs (application program interfaces) for deploying applications on a unified network.
- Functionality in clusters as virtual systems or on physical servers.
- Multiple control nodes can be deployed in a hot/warm cluster configuration.
- Each cluster can support 1000 switches and more than 250,000 new host connections per second.
- Built on an open core (called Floodlight) for use on diverse platforms.
