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.

Abstract: In example implementations, a method is disclosed for a software defined network (SDN) controller assisting an intrusion prevention system (IPS). The method includes receiving an indication that a malicious packet has been detected by an IPS in a communication network. A list of source nodes that have a source Internet protocol (IP) address that matches a source IP address of the malicious packet is determined. A virtual local area network identification (VLAN ID) associated with a source node of the list of source nodes that sent the malicious packet is determined. The SDN controller may instruct an edge switch to block additional packets from the source node of the list of source nodes having the VLAN ID.

Abstract: Migration of profiles between virtual connect domains is described. In an example, a plurality of validations are performed on a profile from a first virtual connect domain virtualizing devices using a first configuration. The profile is updated based on a second virtual connect domain virtualizing devices using a second configuration. The profile is moved for use by a device in the second virtual connect domain.
