Methodology for analyzing the construction of structural redundancy of an information and telecommunications network under the influence of the enemy
Introduction: the problems of building an information and telecommunications network are considered from the position of fragmentary development based on the methodology of implementing structural and topological principles of ensuring survivability in the construction of an information and telecommunications network. Information and telecommunication networks belong to the class of large systems. They cannot be created in a short time and assume fragmentary (evolutionary) development. Therefore, some of its elements can be exploited, others can be designed, and others can be investigated. For this reason, the methodology should include not only synthesis methods, algorithmic and parametric optimization methods (system design), but also engineering design methods (implementation of synthesis results). Purpose: a methodology is proposed for the implementation of structural and topological principles of ensuring survivability in the construction of an information and telecommunications network, including a methodology for con structing a structurally redundant information and telecommunications network, implementing the integration - triad principle of its construction, an algorithm for constructing a reference variant of the network structure and an algorithm for its correlation, taking into account the use of means and methods of counteraction by the enemy. The questions of the structural and mathematical definition of the methodology for constructing a structurally redundant information and telecommunications network that implements the integration - triad principle of its construction, the algorithm for constructing a reference version of the network structure and the algorithm for its correlation, considering the use of means and methods of counteraction by the enemy, are presented. Methods: the proposed methodology can also be used to analyze networks under the influence of the enemy, when it is necessary to modernize the information and telecommunications network with network transformation. Results: the results indicate the adequacy and effectiveness of the methodology for solving the problem of building a network in its design, as well as for analyzing networks under the influence of the enemy, when it is necessary to modernize the information and telecommunications network with the transformation of the network As a result of calculating the ordinal function of the graph reflecting the hierarchical structure of communication nodes of the information and telecommunications network, their hierarchical distribution determining the reference structure of the system is obtained. Within the framework of this structure, its rational variant is being sought. Thus, to assess the adequacy and effectiveness of the proposed network, it is necessary to compare alternative options for building a network. The information and telecommunication network obtained as a result of the application of the proposed construction methodology corresponds in its characteristics to the set goals, i.e. corresponds to a network that is the result of many years of experience and repeated improvements aimed at the most effective mutualexchange of information in accordance with the conditions of the enemy's influence. Discussion: the resulting network is better, since it is more stable when exposed to the enemy, and the existing network satisfies the conditions that exist in this particular period of time, and when exposed to the enemy worsens its performance.
