NetconfController.java, implemented by NetconfControllerImpl.java: tracks all the NETCONF devices, serves as a one stop for connecting and obtaining a device and (un)register listeners on device events.
- NetconfDevice.java implemented by NetconfDeviceImpl.java: represents a NETCONF capable device connected to the ONOS core with his own NetconfSession and his informations saved in an instance of NetconfDeviceInfo
- NetconfSession.java: interface that every type of transport connection to a NETCONF device must implement, represents the single access point for any operation on the device. An example is NetconfSessionImpl: uses an SSH2 Connection and Session to exchange information and perform operations like get/set-config with the physical NETCONF device.
- NetconfDeviceProvider.java: manages any NETCONF device role and all the interactions with the ONOS core.
- NetconfDeviceListener.java implemented by InnerNetconfDeviceListener.java in NetconfDeviceProvider: informs the provider in the ONOS core that a NETCONF device is connected/disconnected.
- NetconfDeviceInfo.java: contains ip,port,protocol,username,password and DeviceId of a NETCONF device; it's used to exchange information about a device without having to pass the device instance itself.
- XMLConfigParser.java: parser for reading and producing XML files to and from the NETCONF device. For now has only configuration reader and edit controllers configuration producer.

An example of NETCONF infrastructure usage is getting and setting controllers on a device. These operations are defined in an ONOS Behaviour, in our case the NetconfControllerConfig.java, that implements ControllerConfig general behaviour. To do the operations on the device you need, in the Behaviour you are creating, the NetconfController, which you can obtainthorugh the DriverHandler. The NetconfController instance now gives you access to all the device or a single device. Once you have the device you are interested in based upon the deviceId you provide you can get the NetconfSession object to comunicate with the device and do operations on the physical device, getting the configuration in case of the get controllers or setting a pre-built new one for the setControllers. XmlConfigParser.java offers a method to extract the wanted information from an XML configuration received from the device and another method to produce the correct XML to set one or more controller on a specific device.
