Abstract
Modern trends in the development of information technology require new approaches to network traffic management. SDNs allow you to shift control layer outside the equipment and perform routing centrally, avoid overloads, and monitor network performance in real time. In recent papers on software-defined networks, the problem of providing quality of service was not studied in detail. Working with queues, limiting the rate of flows, marking the exceeding of thresholds is available in most modern devices working with the OpenFlow protocol. This paper will consider approaches to ensuring the quality of service in various software-defined environments and different versions of OpenFlow, proposed a structural mathematical model for describing queues and working with them within the OpenFlow protocol, and consider a mechanism for fair limiting the flow rate during overloads.
