Abstract: The present disclosure pertains to systems and methods of handling Address Resolution Protocol (ARP) responses in a software defined network (SDN). In one embodiment, a system may comprise a controller in a control plane to generate an address store comprising information associated with a plurality of devices in communication with the SDN. The controller may also program a plurality of network devices in a data plane based on a plurality of communication flows. The network devices may forward traffic according to the plurality of communication flows received from the controller. The network device may also receive: a request from the first device for information associated with the second device, determine that the first device is authorized to communicate with the second device based on the plurality of communication flows, and generate a response to the request comprising the information associated with the second device based on the address store.

Abstract: A software-defined network controller (SDN controller) defines a first network flow to be selectively implemented by a networking device according to a first network operation profile. The SDN controller defines a second network flow to be selectively implemented by the networking device according to a second network operation profile. A memory device of the networking device may store at least first and second network operation profiles for selective implementation based on network packet characteristic matching and/or a “trigger alarm” event. The first network operation profile is implemented when an incoming network packet matches a pre-defined and/or customizable network packet characteristic match template. The second network operation profile is implemented when a “trigger alarm” event is received. A network operation profile may execute a write action to latch, or otherwise trigger, a physical alarm of a networking device or associated device.

Abstract: A software-defined network controller (SDN controller) defines a first network flow to be selectively implemented by a networking device according to a first network operation profile. The SDN controller defines a second network flow to be selectively implemented by the networking device according to a second network operation profile. The first and second network operation profiles are stored within a memory of the networking device to be selectively implemented based on the status of a profile selection input on the networking device. The profile selection input is a contact input in some embodiments. When the contact input is de-asserted, the networking device implements the first network flow according to the first network operation profile. When the contact input is asserted, the networking device implements the second network flow according to the second network operation profile.

Abstract: A software-defined network controller (SDN controller) defines a first network flow to be selectively implemented by a networking device according to a first network operation profile. The SDN controller defines a second network flow to be selectively implemented by the networking device according to a second network operation profile. The first and second network operation profiles are stored within a memory of the networking device to be selectively implemented during different time periods based on a precision time input via a precision time input port on the networking device. In some embodiments, the networking device may detect a network event and implement a network operation profile for a preset time period based on the precision time input.

A memory device of the networking device may store at least first and second network operation profiles for selective implementation during defined event windows.
