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.
