TIME-SENSITIVE PROGRAM-DETERMINED NETWORK Russian patent published in 2020 - IPC H04L12/721 

FIELD: network technology.

SUBSTANCE: such result is achieved by the fact that the SDN controller can determine that the data packet originating from the transmitting device and directed to the receiving device is associated with one of characteristics corresponding to sensitivity to time, characteristics, corresponding to time reference, and a characteristic corresponding to the maximum efficiency principle. Controller can then determine a network path for transporting a data packet from a transmitting device to a receiving end-to-end reception receiver, in order to satisfy said characteristic. Through delay considers the delay time through each level through which the data packet passes after its creation at the application level of the transmitting device. Data packet is then transmitted from the transmitting device through the network path to the receiving device.

EFFECT: technical result consists in enabling calculation of most efficient paths based on sensitivity to time and network load.
