Annotation: The significant grows of cloud computing technology requires the development of new methods for virtualized resources managing. The analysis of OpenStack network module is proposed in the paper. The main components of Neutron and OpenStack interaction with third-party elements are also observed. The main attention pays to OpenStack -SDN integration. The interaction between plug-ins of Neutron and SDN controller are considered. To obtain more information about OpenStack –SDN solution the parameters for different types of SDN controller were analyzed. Performance and reliability of SDN controllers are evaluate in the paper: the experimental model of SDNOpenStack integration was created. Such characteristics of SDN-OpenStack solution as delay, max amount of UDP and TCP data flows obtained in the experiment.
