Practical Estimation of VoIP QoS Based on Correlated Analysis of Transport Protocol Impairments and Perceptual Speech Quality
The request for QoS in VoIP networks can be considered as two-fold: to ensure satisfactory performance at (relevant) protocol levels (IP, TCP/UDP, RTP), as well as at perceptual speech quality level, observed in between end points of the system. In this paper, correlation of the two levels of testing is proposed as the criterion for the overall QoS of a packet based ransmission of speech. Specifically, in a test environment, in addition to signaling protocols decoding and expert analysis. RTP packet jitter and loss have been measured and statistically analyzed. Then these results have been correlated with the results of the objective perceptual speech quality testing, providing the overall practical QoS criterion.
