Estimate Jitter in the G/M/1 System Based on Hypreexponential Distributions
Analysis of the parameters of the functioning of IP-networks in the processing of multimedia streams is a very important task. There are many approaches to assessing the quality of service parameters in the G/G/1 system. But such an analysis is often based on assumptions that do not allow determining the parameters with the necessary accuracy. The paper considers an approach to assess the average value of jitter of multimedia trafc recorded on a real network. The analysis of jitter of multimedia trafc in the G/M/1 system is given. Jitter estimation is based on the G/G/1 system approximation by the system, which has a hyperexponentially distributed arrival and servicing time. To determine the hyperexponential distribution parameters, well-known approaches based on the assessment of the initial moments of the frst and second order have been used.
