Abstract: In some examples, a network controller includes a flow repository and a consistency verification engine. The flow repository may store a dataflow configuration previously specified by an application. The consistency verification engine may access the dataflow configuration from the flow repository, retrieve flow table entries from a flow table of a network device, identify an inconsistency between the dataflow configuration previously specified by the application and the flow table entries of the network device, and respond to the identified inconsistency.

Abstract: A device is authenticated for communication over a network based on a sensor data signature and a traffic pattern signature. The sensor data signature and the traffic pattern signature identify the device. A determination is made whether the sensor data signature corresponds to one of a plurality of recognized sensor data signatures. A determination is also made whether the traffic pattern signature of the device corresponds to one of a plurality of recognized traffic pattern signatures. The device is authenticated for communication over the network responsive to determining that the sensor data signature corresponds to one of the plurality of recognized sensor data signatures and the traffic pattern signature corresponds to one of the plurality of recognized traffic pattern signatures.

Abstract: In some examples, a Software-Defined Network (SDN) controller includes a processing resource a memory resource including machine readable instructions to: (1) run a first SDN application to monitor usage of a control channel between the SDN controller and a device in the control domain of the SDN controller, (2) run a second SDN application that uses the control channel to communicate with the device, (3) and throttle the use of the control channel by the second SDN application when it is determined, by monitoring usage of the control channel with the first SDN application, that control channel usage satisfies a usage criteria.
