Abstract

Multiservice telecommunication network is studied under adaptive (dynamic) routing in accordance with LLR method and GOS parameters are analyzed at connection level with effect of blocked call retrials. The mathematical model is built to take into account the influence of repeated attempts to get connection. On the basis of this model the algorithm is proposed to approximately evaluate the intensity of repeated attempts flows and call blocking probability. The accuracy of constructed analytical model is tested by numerical results obtained with the help of discrete event simulation.
