Voice over IP Wide Area Quality Measurements
Users of Internet telephony applications demand good quality audio playback. This quality is largely dependent on the instantaneous network conditions as well as both the time and day. Equally, if not more important, is the reliability of using the Internet for voice communication. Calls that cannot be completed are unacceptable for all users. In this paper we describe a scheme for measuring ne...
متن کاملSIP over IP VPN: Performance Analysis
With rapid growth in use of multimedia applications, including IP Telephony (also known as Voice over IP), the demand for security and privacy of communications has significantly increased. Given the fact that IP Telephony utilizes public IP infrastructure, deployment of IP VPN is one approach to protect traffic of interest. However, VPN is presumed to have a negative impact on VOIP performance...
متن کاملWide Area Measurements of Voice Over IP Quality Revisited
Time, day, location and instantaneous network conditions largely dictate the quality of Voice over IP calls. In this paper we present results of VoIP quality mainly in terms of packet jitter and loss. This work revisits our objective of measuring VoIP quality in 1999 enabling us to make comparisons with the results we obtained three years ago. It also allows us to improve the measurement infra-...
متن کاملWide Area Measurements of Voice over IP Quality
Time, day, location and instantaneous network conditions largely dictate the quality of Voice over IP calls. In this paper we present the results of over 18000 VoIP measurements, taken from nine sites connected in a full-mesh configuration. We measure the quality of the routes on a hourly basis by transmitting a pre-recorded call between a pair of sites. We repeat the procedure for all nine sit...
