The analysis and calculation of not Poisson models of the traffic in computer networks

In article are considered of not Poisson the models of the traffic described «with heavy tails» by distributions of intervals of time between events in streams. It is shown that such models worsen indicators of productivity of network structures in comparison with of the Poisson streams. Hence, of the Poisson teletraffic models underestimate delays and other important indicators of quality of functioning of networks of telecommunications.
