Measuring Internet telephony quality: where are we today?

Users of Internet telephony applications demand good quality audio playback. This quality is largely dependent on the instantaneous network conditions. In this paper we describe a scheme for measuring network connections as well as a motivation for including a new metric when assessing quality. The tests included a wide range of geographically distributed sites and our results can give useful feedback to users, operators and developers of Voice over IP applications. The results indicate that Internet telephony is feasible on today´s Internet but we should envisage some problems if the Internet continues to grow at the rate so far
