Abstract :
In recent years, IP videoconferencing applications are promoting. Since video over IP is sensitive to delay and jitter, network providers are now deploying quality of services (QoS) to support real-time application requirement over their network. Our goal in this paper is to disseminate a performance monitoring architecture for IP videoconference, which is able to both detect end-to-end QoS degradation and locate where it occurs in the network path. We use this architecture to study how QoS affects videoconferencing performance and to analyze what QoS configuration parameter is most suitable to guarantee the delivery quality of IP videoconference.
