Analysis software needed to ensure control over data packets in the software-configured networks

The paper presents the concept of Software-Defined-Networking, and the history of programmable networks and associated review of the latest standards. One of them, the OpenFlow protocol, played an important role in promoting the concept of SDN, significantly influenced research and industry. Consider in more detail the basic principles of OpenFlow. To debug the software, it is necessary to ensure the control of packets in the network, although formally verification can be used to determine the correct flow. This is necessary in order to generate detailed network images and also to inspect function parameters under certain network conditions. From the standpoint of security, OpenFlow's potential for new security schemes has not been well understood. When analyzing packets in a Packet message on a network controller, it follows that they can be used to identify and detect the penetration of the connection before the stream is configured. While new attack vectors were investigated for network security, the centralized network controller and control channel remain partially unprotected.
