Milokum Y. Models and methods of providing of quality of service in the protected computer networks

Dissertation is devoted to improving service in the protected computer networks. The purpose of work consists in development of models and methods of improving service, reliability of functioning of the protected computer networks. The tasks of analysis of models and methods of monitoring of parameters of traffic of computer networks were put and decided. Analysis of existent models of the systems of defense of computer network was completed. Developments of model of informative co-operation of the computers systems were made. The researches of the model of informative conflict in the conditions of ambiguity were developed. The methods of the conflict control for defense of segment of network were created. The system of the anomalies of traffic detection in computers networks is researched. The modified multilevel system of defense of network perimeter of protected network is done. Practical significance of the got results is next: theoretical results and conclusions are led to concrete algorithms and computer programs; the results of theoretical researches of descriptions of network are given in the closed-form analytical expressions. The proper diagrams are comfortable for use in the practical tasks of the analysis of descriptions of the systems of defense of heterogeneous networks of different scale and appliance are built. The model of informative co-operation of the computers systems, model of informative conflict in the conditions of vagueness, method of conflict control for defense with application to the segment of network, the algorithm of the system of the traffic anomalies detection in computers networks have practical asset.
