Sažetak

This paper presents a research on the influence of packet loss on quality of Internet speech connection. A novel simulation method is proposed to determine time distribution of the loss impairment factor, which is one of the parameters necessary to determine connection quality according to E-model. Several examples illustrate the use of method for the analysis of links with random and burst packet loss and with the loss as one recorded real trace. Use of the presented method can provide better insight and more data about the quality of Internet telephony.
