MANAGEMENT OF ENTERPRISE SOFTWARE DEFINED NETWORKS [№ 13 ' 2015]
The existing solutions for enterprise networks have a number of drawbacks. First, there is a problem deciding where to install the security tools, which are usually placed at the subnet borders. This leads to the fact, that they only handle the traffic transmitted through them. It reduces the level of network security. Second, there is the problem of the efficient network traffic routing while ensuring quality of service at the appropriate level. To solve these problems we propose the usage of the software-defined network technology. On the base of this technology, the prototype's architecture for network security system of enterprise SDN is proposed. It includes the implementation of the algorithms for firewall, authentication, routing and delivering QoS. The proposed authentication algorithm for enterprise SDN supports IEEE802.1x, EAP, RADIUS, LDAP, WPA2-EAP. SDN is used to isolate the data streams of different users with the ability to create any number of isolated virtual networks without restrictions of VLAN, and to implement additional access control by firewall. The experimental results of the prototype research show the efficiency and suitability of the developed algorithms for enterprise SDNs. The results can be used to deploy enterprise SDNs in companies of the Orenburg region.

DEVELOPMENT OF EFFICIENT GENETIC ALGORITHM FOR ROUTING AND DELIVERING QOS USING SOFTWARE-DEFINED NETWORKS [№ 1 ' 2015]
This paper presents results of research aimed to the development of efficient routing methods for corporate software-defined networks and cloud systems. Optimization problem of proactive traffic routing was formalized. It considers flexible constraints on providing QoS parameters for data flows — minimum guaranteed bandwidth and maximum guaranteed delay. Genetic algorithm was proposed for solution of this problem. It is based on software-defined networking, which is used for collecting information on network state and installing routing rules to the switches. Implementation of this algorithm was estimated by software-defined network simulator, and showed good efficiency. In the future we plan to study it in detail using simulator and a real software-defined network.

USING OF CUSTOMS POLICY INSTRUMENT IN AN EFFORT TO AVERT ILLEGAL OUTFLOW OF CAPITAL [№ 4 ' 2010]
The author of this article regards the problem of illegal outflow of capital from the Russian Federation, analyzes the value of capital flight on the base of balance of payments data at the period 2006–2008, and gives the appraisal of illegal outflow of capital from Orenburg region at revealed violations according to the Code of administrative violations. Also the complex of measures of averting of illegal outflow of capital is suggested in this work.
