The method of choosing a wireless access network in a heterogeneous environment based on the theory of fuzzy sets has been improved. This method allows for a centralized, well-founded decision to carry out a horizontal-vertical handover procedure based on a group of QoS-dependent criteria that depend directly on the properties of the radio interface of the network system. The method also allows adaptation decision-making rules, depending on different telecommunication conditions and network policies. A simulation model of the heterogeneous network has been developed. The model allows to automate investigation of the proposed method of selecting an access node based on the theory of fuzzy sets. The model enables configuration of a large number of simulation parameters using auxiliary mathematical models, in particular for describing and predicting user traffic processes.

“…As a result, the creation of TUN/TAP (Tunnel/ Test Access Point virtual network adapters slow down the program, and since the DPI system must function at least with the rate of the input flow, then the rate plays an important role. However, for software development, using WinDivert, you need to undergo a certification procedure and a digital signature for drivers [68][69][70]. Certification is performed to minimize the risk of operating system crash, since WinDivert works at a kernel level where any developer error can lead to an OS (Operating System) failure.…”

In this paper, to solve the problem of detecting network anomalies, a method of forming a set of informative features formalizing the normal and anomalous behavior of the system on the basis of evaluating the Hurst (H) parameter of the network traffic has been proposed. Criteria to detect and prevent various types of network anomalies using the Three Sigma Rule and Hurst parameter have been defined. A rescaled range (RS) method to evaluate the Hurst parameter has been chosen. The practical value of the proposed method is conditioned by a set of the following factors: low time spent on calculations, short time required for monitoring, the possibility of self-training, as well as the possibility of observing a wide range of traffic types. For new DPI (Deep Packet Inspection) system implementation, algorithms for analyzing and captured traffic with protocol detection and determining statistical load parameters have been developed. In addition, algorithms that are responsible for flow regulation to ensure the QoS (Quality of Services) based on the conducted static analysis of flows and the proposed method of detection of anomalies using the parameter Hurst have been developed. We compared the proposed software DPI system with the existing SolarWinds Deep Packet Inspection for the possibility of network traffic anomaly detection and prevention. The created software components of the proposed DPI system increase the efficiency of using standard intrusion detection and prevention systems by identifying and taking into account new non-standard factors and dependencies. The use of the developed system in the IoT communication infrastructure will increase the level of information security and significantly reduce the risks of its loss.

“…The advantage of the developed traffic generator is that, unlike the known ones, it allows you to control the generated flow without the need for synchronize the input and output interfaces and to determine the packets delay of flow. It allows you to evaluate the parameters of service of hardware and software telecommunications facilities of any purpose [53][54][55][56][57][58][59].…”

The development was carried out using the Qt5.2 integrated development environment, which uses the programming language C++. The main advantage of this environment is that the code written in it can be compiled to different platforms (for example, Windows, Linux, Mac OS). A software router based on a modular architecture has been developed. It uses the socket technology, which allows forming a program-oriented packet network with any topology, including full-coupled topology. A network traffic generator to test the developed software router has been designed. We proposed a scheme to measure the packet processing time of a router using a specialized packet-capture network interface cards (NIC 1 and NIC 2) and a novel traffic generator installed on PC. Based on an experimental test bed we confirmed that our software router provides a cost-efficient alternative to the expensive, special hardware router CISCO 2801.
