Abstract
Some embodiments provide a set of one or more network controllers that communicates with a wide range of devices, ranging from switches to appliances such as firewalls, load balancers, etc. The set of network controllers communicates with such devices to connect them to its managed virtual networks. The set of network controllers can define each virtual network through software switches and/or software appliances. To extend the control beyond software network elements, some embodiments implement a database server on each dedicated hardware. The set of network controllers accesses the database server to send management data. The hardware then translates the management data to connect to a managed virtual network.
