The operating mode telecommunication system of remote control depends both on parameters of an entrance stream of inquiries, and from characteristics of productivity of the system: numbers of channels and speed of each channel. One of the major sizes determining an operating mode of system, the delay of service (it is a holding time of one inquiry). The purpose of work is research self-similar properties of an information stream of the data, an estimation of influence self-similar properties a stream of inquiries about characteristics of telecommunication systems of remote control by experiment, at various operating modes, for the adequate description and modeling of the given class of systems. The carried out researches have shown, that the processes proceeding in telecommunication systems of remote control have a self-similar properties and render essential influence on time characteristics of system. The analysis of experimental statistics of dynamics of work of system of remote control has shown that the information stream of the data possesses long-term dependence (self-similarity). On the basis of the analysis time characteristics it is determined, that at work of system of remote control as experiment (at small values λ) forms of distribution of delays of service p(T/Tmax) are close to exponention. At increase in intensity of inquiries λ when the system of remote control passes in a non-stationary operating mode, distribution p(T/Tmax) gets character of the sedate dependence described by distributions with «heavy tails», for example, distribution Paretto. Results carried out research enable to estimate characteristics of quality of service of telecommunication systems of remote control by experiment in conditions self-similarity character of an information stream of the data.
