Overlay telecommunication networks synthesis taking into account data units and using multilayer graph
An important step of telecommunication systems design is selection of parameters of its elements. This issue is known as the issue of parametric synthesis. Existing solution methods are based on simple stream models, which became outdated for the modern multiservice traffic. According to the research, the models of selfsimilar processes describe the traffic properties more precisely. Another effect that must be taken into account is overlay principle of modern telecommunication network construction, when data units, transmitted in networks, are different. The paper gives a method for determining the parameters of self-similar stream for various network levels, taking into account the changes of transmitted data units, and the recommended method for parametric synthesis using multi-layer graph model. The proposed method can be used when designing overlay multiservice telecommunication networks with various types of data units
