Abstract

The present paper relates to performance and quality of service evaluation for VoIP (Voice over IP) and desktop videoconferencing services in IP networks. Simulation-based performance measurements consist in the generation of performance statistics obtained by measurements realized by simulation on the subscriber interface. They include detailed measurement of call quality, call set-up quality and availability. The tests are accomplished by emission of non-disturbing additional test traffic. The real-time QoS monitoring is based on non-intrusive analysis of real call parameters. The advantage of this method is the exhaustiveness of the analyzed call. The QoS measurements are mainly service availability and call set-up quality.
