A VoIP measurement infra-structure

Abstract [en]

Time, day, location and instantaneous network conditions largely dictate the quality of Voice over IP calls. In this paper we describe a VoIP measurement infrastructure to measure the delay, loss and jitter of simulated phone calls on the Intern et. We measure the quality by transmitting a simulated voice call between chosen sites and carefully recording the subsequent packet arrivals at the receiver. We have gathered more than 25,000 sample VoIP sessions from nine global sites. This is our second and more detailed attempt at measuring VoIP quality. This second phase has also focused on the effects of packet size, network asymmetry and silence suppression on measuring jitter, delay and loss. We have made the sessions and tools available for future investigations. Generally the quality of VoIP is excellent within the US and Europe and has improved since our last measurements. Finally this paper concludes with what we have learnt from two efforts of measuring VoIP quality on Wide Area Networks.
