In the article the results of researches of variant of exponential GERT-network (the network the branches of which are characterized the exponential distributing) are presented for the design of probabilistic-temporal descriptions of multiservice communication channel. Analytical expression is found for the estimation of closeness of distributing of probability of time of delivery of report. Built and analysed the graphs of function of distributing and closeness of distribution of probabilities of casual size of time of delivery of report. Dignities and lacks of mathematical model of multiservice communication channel are exposed by a GERT-network.
Keywords: GERT-network, mathematical model, time of delivery of report, multiservice communication channel
