APPLICATION OF THE MULTI-CRITERIAL APPROACH FOR THE SYNTHESIS OF MULTISERVICE TELECOMMUNICATION NETWORKS

Abstract

The most effective use of multi-service networks occurs with traditional communication operators, which significantly expands the range of services. For the corporate market, the consolidation of all remote divisions into a single multiservice network can significantly increase the efficiency of information exchange and ensure timely availability of data. With the ability to exchange large amounts of data between offices, you can schedule conference calls and video conferences with remote units. All this speeds up the response to changes in the company and ensures timely and optimized management of all processes. A multiservice network is a general-purpose, multi-purpose environment designed to transmit voice, images, and data using packet-switched technology. It is characterized by the reliability characteristics of the telephone network (compared to the unguaranteed quality of communication on the Internet) and provides a low cost of transmitting a unit of information (close to the cost of data transmission on the Internet). The main task of multi-service networks is to ensure the operation of heterogeneous information and telecommunication systems and applications in a single transmission environment, where a single infrastructure is used to transmit ordinary traffic (data) and other information traffic (broadcast, video, etc.). The design algorithm of multi-service telecommunication networks (MSTN) is a process of developing system and technical solutions during their construction with shortterm, medium-term and long-term development. The optimization of MSTN design is carried out on the basis of the application of the principles of decomposition, systematic and iterative design, as well as methods of sequential optimization and probabilistic convolution when obtaining generalized criteria. The proposed method makes it possible to move from the solution of a largedimensional optimization problem to a sequence of tasks that are interdependent in terms of input and output data. As a result, a stepby-step iterative synthesis of the MSTN structure and the selection of the values of the internal parameters by means of parametric optimization are provided, in which the requirements for the quality of functioning and the cost of the project are met. At the same time, the theory, and methods of structural and parametric synthesis of multi-service telecommunication overlay networks were developed based on the development of new models of multi-level, multilayer networks and methods of structural and parametric synthesis, which take into account the presence of physical and logical connections between layers of overlay networks.
