Nowadays the traditional architecture of computer networks (CN) requires big resources for support of transmission of growing data flows for large number of devices taking into account quality of service (QoS). It allows to solve a wide range of tasks on the organization of data exchange, providing development of information society. Complexity in service of CN is combined often with incomplete compatibility of network decisions that it involves dependence on hardware manufacturers. The mismatch of client's needs and solutions proposed in the market led to appearance of new concepts of creation and organization of data networks - software-defined networks (SDN) on the basis of OpenFlow (OF) protocol. SDN technology on the basis of OF protocol suggests to refuse such tendency of development of CN, having executed transition from separate network elements and network, to platforms in general. Control of network flows happens to the help of applications, which they are possible to optimize flows to find the shortest path, as it is done by the modern distributed routing protocols, and also to optimize network for the maximum use of communications. The purpose of work is development of conceptual approach of dynamic load balancing of data flows in SDN with QoS of different network applications.
