چکیده (انگلیسی):

The paper represents the research results of studying the switches. The model of a switching link has
been suggested. The switch has been presented in the form of a Queuing System (QS), the study of
dynamic characteristics of switches has been undertaken and the adequacy of the proposed model of a
switching link to actual switches has been valued. The maximum error of the modelling is no more
than 5%, which indicates the sufficient adequacy of the switching link as related to the evaluation of
its probability-time characteristics. The accuracy given is eligible for practical and engineering
research works. The self-similar traffic characteristics causing an overload rise when passing through
the switching links have been studied by means of simulation modelling. The simulation test
conducted of the traffic passing through the switching link showed three characteristics to be
significant: Intensity, Fano parameter and Hurst exponent.
