Hybrid Model Management of Information Messages in Multiservice Networks

Problems of multiservice network modeling on the basis of hybrid methods – methods of graph theory and queue system are considered in the article. Model NGN-network is presented in the form of exponential Petri net. For calculation of probabilistic and time characteristics of network on the basis of Petri net analytical expression was received. On the basis of this expression calculation of time allocation density of message transfer that depends on special points’ allocation of distribution function is executed. The model can be used for the study information processes in multiservice telecommunication networks, in development of new protocols, algorithms and control programs of channel resources in NGN-networks. The use of exponential stochastic models of Petri net will give the opportunity of results use received in analytical form (functions, distribution density) for conducting comparative analysis and researches, more complicated information-telecommunication system by mathematical methods.
