Assessment of Local Area Network Effectiveness when Solving the Main and Supporting Tasks

Purpose of research. is to assess the performance of the infrastructure of the Data processing system (DPS) of graphic user interface (GUI), taking into account the functional purpose and operation conditions of its elements. The object of the study is the GUI DPS since it is a typical element of the automated-information system (AIS) infrastructure of an enterprise, based on the centralized two-level structure of LAN in automated working place (AWP) and computer (servers).

Methods. The article presents a model of functioning of a local area network for processing geospatial information, organized using the client-server technology, which takes into account the impact on the overall performance of AWP parameters that perform not the main function, but the supporting one. In modern conditions, the amounts and diversity of data used in planning, organizing and implementing large information projects significantly increased. In addition to data from space monitoring systems, the flow of geodesic, meteorological and geophysical information is growing, which needs to be analyzed and taken into account when preparing and conducting projects. Even today, the necessary types of data in the required amounts cannot be accepted, processed and integrated using the existing technical means of ground infrastructure.

Results. The research performed in the article showed that the functional reliability factor significantly affects the basic functional properties of the considered GUI DPS so it is necessary to take into account functional reliability of the elements when analyzing and choosing the systems of the class under consideration.

Conclusion. The contradictions that have arisen between the increased flows of information and the existing possibilities of their processing and use necessitate application of new tools, in particular, based on the principles of geo-information technology and geospatial information.
