Executive Summary

Voice over IP (VoIP) is now available on many IP networks carriers in the world with lower cost compared to Public Switched Telephone Network (PSTN). However, current IP networks only offers best-effort services and were designed to support non-real-time applications. VoIP demands strict Quality of Services (QoS) levels and real-time voice packet delivery. The QoS level of VoIP applications depends on many parameters; in particular, One-Way-Delay (OWD), jitter and packet loss have an important impact.
