    An Analysis of SDN-OpenStack Integration
    (KHARKIV NATIONAL UNIVERSITY OF RADIO ELECTRONICS, 2015) Tkachova, O.; Abdulghafoor Raed Yahya; Mohammed Jamal Salim
    This paper is devoted to analysis of integration of SDN solutions to the OpenStack. Architecture of networking OpenStack module or Neutron and plug-ins for communication with SDN is considered. Different types of SDN controllers also considered in the paper. An experimental model of SDN-OpenStack integration was created according to the solution. Such characteristics of SDN-OpenStack solution as delay, max amount of UDP and TCP flows obtained in the experiment

    Analysis of the effectiveness of the load balancing mechanisms in Software-Defined Networking
    (ХНУРЭ, 2016) Tkachova, O. B.; Abdulghafoor Raed Yahya; Hassan Mohamed Muhi-Aldeen
    The paper is devoted to analysis of load balancing mechanisms in Software-Defined Networking. Software-Defined Networking has a lot of benefits, however the use of classical traffic engineering principles for traffic management in Software-Defined Network presents a problem. Analysis of the effectiveness of management mechanisms, and in particular, algorithms for network load balancing that enable to take into account the centralised structure and heterogeneous nature of traffic in software-defined networks is proposed.

    Methods for contradictions detection in OpenFlow protocol specification
    (ХНУРЭ, 2015) Tkachova, O. B.; Abdulghafoor Raed Yahya
    Methods of contradictions detectin in the requirements of the OpenFlow protocol specification are offered: the method of successive comparison of formalism requirements and the method of construction of the reachability tree of protocol states graph. The method of sequential detection and collation of all specification formalisms that containe the statement being verified makes it possible to solve effectively a number of narrowly focused tasks. The method for checking the reachability of the graph of states corresponding to the requirements of the specification, which makes it possible to identify all the multiple contradictions within the specification or its fragment.
