Modeling the effects of burst packet loss and recency on subjective voice quality

Abstract

This paper describes VQmon, a non-intrusive monitoring technique for Voice over IP networks that is computationally efficient and suitable for integrating or embedding into VoIP gateways or IP Phones. This uses an extended version of the ITU G.107 E-Model incorporating the effects of time varying packet loss and “recency”. A 4 state Markov model is used to represent the time distribution of packet loss during a VoIP call. QoS, Voice over Packet, E model, subjective quality A.
