摘要：The aim of the study is to develop a confident algorithm for assessing the bandwidth of an IP channel affecting image quality during transmission of the video signal and signals for tomography. The research method is based on the Monte Carlo method. The development of an algorithm for assessing the bandwidth based on information identifier (IP packet delay time and delay variation) is discussed in this paper. The experiments have been carried out taking into account the size of the information packet of the video signal and the signals for tomography. The outcomes of this study embrace the developed model of an IP channel, its software implementation, which allows assessing the dynamic bandwidth. The developed model enables to perform comparison of the efficiency of a compressor, a router, and a server with digital signal processing by the criterion of confidence of packet servicing time in the IP channel. Analytical calculations have been carried out for the purpose of quantitative calculation of the obtained confidence to confirm the results of modelling. The results of modelling allow taking into account the main interrelated factors that appear in the form of distortions in the image during the transmission of video signals and signals for tomography. The article discusses the results of the �Analysis of the functioning features of multi-service IP networks� project. The present paper reveals new knowledge about the development of confident algorithms that allow assessing the probability of delivery, packet loss, and IP channel bandwidth with a given probability. In prospective, these studies are necessary and relevant for performing remote surgical operations and decoding tomography images remotely.
