Abstract. A poly-model description of the problem of control over information processes in a distributed information and computer network with a reconfigurable (configurable) structure, has been developed. The information processes under investigation include the processes of data receiving, transmitting, processing, and storing. In addition, it is assumed that due to the limited bandwidth of the data transmission channels, as well as the computing resources of the network, data losses in the specified network are possible. The proposed poly-model description includes static and dynamic models of control of information processes in information and computer network. Methods of mathematical programming (for a static model) and the method of local sections (for a dynamic model) are used to calculate indicators of the quality of control over the information processes. Information on software implementation of the developed model-algorithmic support for solving problems of calculating, analyzing, and optimizing the quality indicators of the information processes is presented.
Keywords: information processes, information and computer network with reconfigurable structure, model-algorithmic support, quality indicators of information process management
