Increasing the fault tolerance and availability of software defined networks using network equipment control based on multiobjective optimization by service quality parameters

Control methods for software defined networks and techniques for evaluating their operation using the multiobjective optimization apparatus are considered. The methods are based on monitoring the Quality of Service (QoS) parameters and ensuring network load balancing, higher response speed, and the availability and fault tolerance of OpenFlow-compatible network equipment and software defined network as a whole.
