Infocommunication Networks Design with Self-Similar Traffic

The parametric synthesis is one of the planning stages of infocommunication networks. Recent studies of network traffic properties have shown that models of self-similar processes (self-similar traffic) describe traffic in networks more accurately. In this study, based on previously known studies of self-similar traffics, infocommunication network synthesis methods have been proposed. Using the proposed models and calculation expressions allow to solve the problems of parametric synthesis by the known characteristics of the input traffic flows. The solution method involves the distribution of traffic along the routes, determining the parameters of aggregated traffic in the communication channels, determining the bandwidth of the communication channels. The correctness of the results obtained by this method was verified using modeling by comparing them with estimated values, and also measured in segments of real networks. As a result of the simulation the reliability of the proposed method for determining the parameters of aggregated self-similar traffic and the method of parametric synthesis has been proven.
