The approach to modeling virtual local area networks in the corporate information systems

Saenko I.B., Starkov A.M.

The relevance and objective necessity of applying the technology of virtual local area networks (VLAN), which allows us to increase the security and throughput of a corporate information system using existing switching equipment, are substantiated. The methods for creating virtual local computer networks in corporate information systems has been developed, which makes it possible to find the optimal variant of VLAN organization that meets the requirements.

The requirements and criteria for the corporate information system, its technical basis – the local computer network, as well as the telecommunication technology – the virtual local computer network are investigated. Based on modern requirements, a variant of a well-off and non-redundant system of parameters characterizing the quality of information services provided in a corporate information system has been proposed. It is assumed that this system must include parameters that take into account bandwidth, the quality of information services provided, as well as the security policy of the corporate information system. Analyzed simulation tools for creating local computer networks, as well as approaches to solving optimization problems using evolutionary (genetic) algorithms, since the task of finding the optimal variant for constructing virtual local computer networks is NP-complete and refers to problems that are unsolvable by formal methods in a reasonable time.
The subject of the research is the role and place of virtual local computer networks in corporate information systems and the potential of their application.
The aim of the work is developing the methods for creating the virtual local computer networks in corporate information systems.
Practical significance: the essential practical aspect of the proposed approach is the fact that the existing empirical recommendations on the organization of virtual local computer networks do not allow us to make full implementation of the LAN operating indicators during the transformation of the corporate structure. In this case, the chosen variant of the organization of virtual computer networks should provide indicators of the quality of corporate information system operating not lower than the required ones.
