Modern trends in the development of information technology have led to the fact that entire infrastructure is gradually becoming software-controlled. Modern hyper-converged solutions use software-defined networking and soft switches for a hypervisor networking subsystem. The aim of the work is to study traffic processing in hyperconverged structures with software switching based on traditional approaches and OpenFlow. The features in the implementation of hyperconverged solutions network infrastructure are considered, approaches to the study of software-controlled environments are described. A model of internal structure of converged node traffic processing combining the functions of hypervisor, storage system and switch is proposed. Interface models that reproduce traffic switching in usual way and with higher-level OpenFlow processing are developed. The approaches to the implementation of developed models based on experimental studies of network equipment are described. The results of an experimental study of network node and a synthesized model showing the possibility of implementing the proposed approaches within the specified accuracy are presented.

Key words: modeling, OpenFlow, switch, traffic, QoS.
