Description: Problems are analyzed during creation of computer system for environmental monitoring of Ukraine. Problems of access to distributed data of computer system are discussed. It is considered a scenario of remote access to computer network of environmental monitoring; such access can be implemented from unsecure environment through public networks and, therefore, construction tools of the corporate network shall ensure security of network interaction. The topology and features of a computer network of environmental monitoring system are surveyed. It is proved that the computer network of environmental monitoring system is hybrid, which significantly complicates the problem computer system data access monitoring. Inherent feature of hybrid heterogeneous communication networks is in such specific properties of a traffic, as fractality, self-similarity or scale invariance. Simulation of such traffic is a complicated process and classical models, which use Markov processes, do not allow to construct a model, which is adequate to the surveyed process; it significantly reduces possibilities of computer system data access monitoring. The paper proposes a traffic model for hybrid computer network that considers features of the traffic; such model allows data transfer control.


Keywords: monitoring, distributed data, computer system, computer network, control methods
