Research objective is the solution of a relevant problem of development of optimum strategy of management of processes of distribution of computer epidemics, design of local area networks which as much as possible protect network from viral infection with the structure as extensive damage to ordinary users of computers and local area networks of the enterprises, organizations, banks, objects of power supply is caused by epidemics of various computer viruses.The leading method of a research of a problem is creation of a mathematical model of branched chain process of distribution of computer network viruses with playing of options of succession of events, studying on model of efficiency of actions in fight against spread of viruses, a possibility of modeling of “epidemic” on the selected configuration of network for exact assessment of security of network from viruses.The new device of mathematical modeling and forecasting of branched chain processes is presented in article, the model carries out analytical conversions and numerical calculations, builds geometrical images of the proceeding branched chain epidemics of network viruses in real time. Process modeling of spread of network viruses is implemented in two stages: identification of structure of communications of intermediat of chain reaction (computers) of network – “recognition of the prefractal graph” and spread of “infection” on network in the form of chain branched process – “a covering of the prefractal graph”.The theoretical and practical importance of this work consists in adaptation of the instrumental office of prefractal graphs to a solution of problems of a spatio-temporal course of branched chain processes in virologic applications. Materials of article are of practical value at a research of distribution of global chain epidemic the new model device – the vertex costal weighed prefractal columns.

Keywords: computer viruses, computer network, priming, fractal, prefractal and weighted graphs.

MATHEMATICAL MODEL OF OPTIMIZATION OF THE NETWORK INFRASTRUCTURE OF A DISTRIBUTED ENTERPRISE SYSTEM ON A CLOUD, MISTY AND EDGE TECHNOLOGIES

This article describes the formulation of a mathematical model to optimize the structure of the computer network of a distributed corporate information system based on a multi-level topology. Multi-level topological structure allows you to present the network structure, which includes a detailed description of the relationships between such network objects as active equipment, workstations and servers at different levels of the model, to show as a whole a variety of aspects of data transfer management with support for QoS protocols, technical and software implementation, information space and management. As a result, the design of the computing network of the corporate system can be performed as the development of a single network infrastructure of distributed software and hardware, which includes interconnected and interacting subsystems that solve functional tasks for the management and planning of the enterprise activities within a single approach to achieve the goal of obtaining an optimal architecture and meet the complex system and functional requirements for performance, bandwidth, reliability, etc. The paradigm of cloud, foggy and boundary calculations is used, which allows to build a modern network infrastructure within the framework of the industrial IoT concept. The most typical example of the use of this paradigm can be intelligent power supply networks, distributed monitoring systems for the transportation of gas or oil products, distributed systems of an industrial enterprise. To solve the problem, it is proposed to use an approach based on a modified genetic algorithm. The results of the experiments are presented.

Keywords: multi-level topological structure of distributed corporate system, computer network, cloud computing, fuzzy computing, edge computing, genetic algorithm.
