METHOD FOR AUTOMATIC CONFIGURATION OF OpenFlow SWITCHES AND OpenFlow ROUTERS Russian patent published in 2015 - IPC H04L12/70 

FIELD: radio engineering, communication.

SUBSTANCE: method for automatic configuration of OpenFlow switches and OpenFlow routers comprises modifying network traffic tables of OpenFlow equipment. A network packet is forwarded to the controller of a software-configurable network with an included module for determining the write priority in the network traffic table, wherein the set of quality parameters of the network traffic is determined using parameters which correspond to a class of traffic with which said packet is associated, and the priority of the packet specified by the first three bits of the ToS byte; if the ToS byte is not specified in the network packet, the entry corresponding to the network packet in the network traffic table is assigned the lowest priority; if the ToS byte is specified in the network packet, the packet is associated with one of three traffic classes, and the packet is then assigned a write priority in the network traffic table, calculation of which is carried out based on a weight coefficient and an OpenFlow statistics parameter corresponding to a selected traffic class, and also based on the packet priority specified by the first three bits of the ToS byte; the controller of the software-configurable network, in accordance with the OpenFlow protocol, then generates an instruction to add a new entry into the network traffic table of the OpenFlow switch or OpenFlow router.

EFFECT: faster operation of OpenFlow switches and OpenFlow routers when processing network packets.
