Increasing the robustness of computer networks by using hybrid centralized-distributed topology

Abstract

The paper presents the results of the structural synthesis of the hybrid centralized-distributed system of data generation, transferring, storing and restoration. A system of data generation, transferring, storing and restoration is proposed, which includes peripheral nodes made with the possibility of data generation and storing and their subsequent transferring via communication lines to a central node for storage. Each of the peripheral nodes is additionally connected with each other peripheral node by communication lines, and communication lines provide the ability to transfer data, generated in each of the peripheral nodes, for storage on one or several other peripheral nodes and the ability to transfer data to one of the peripheral nodes and to restore data on it in case of the central node loss. A method using the specified system is also proposed. The study objectives are to provide a stability high level of the system and method of generation, transferring, storing and restoration data to data loss, including possibly the holistic body of data, with data loss at the central and one or more peripheral nodes of the system while reducing risk of unauthorised access to data and level of energy consumption. The objectives of the study are achieved by the fact that the pairwise peripheral nodes connect with all other peripheral nodes via communication lines, while the simultaneous connection of all peripheral nodes with the central node via communication lines allows ensuring the integrity of data available in the data generation and storing system in case of complete data loss on the central node and one or more peripheral nodes with a limited number of data copies generated in each of the nodes. Research results can be used in database management systems, server network topology, cryptocurrencies, the financial and banking sectors’ information systems, objects and processes automatic control systems, etc. In addition, the results of the study can be used in the development of the concept of network-centric warfare.
