Abstract

Voice over IP is a hot topic for the networking technologies. Delay and delay jitter are the important measures of QoS particularly for the voice traffic in the network environment with bursty background traffic. This paper studies the performance behavior of delay and delay jitter at the IP packet level by using the transient queuing solution. The analysis focuses on the voice over IP traffic going through a IP router with the bursty background traffic over network. We study the individual effects of various traffic parameters on the jitter behavior of packet voice stream multiplexing background traffic with different bursty characteristics in the IP router. The numerical results for the investigation of the effects of delay and delay jitter to a speech sample are presented
