Monitoring End-to-End Quality of Service in a Video Streaming System

Todaypsilas Internet relies on best-effort delivery in which no guarantees regarding transmission quality are employed. This is problematic in the field of video streaming due to its sensitiveness to transmission quality fluctuations. The ability to measure the experienced level of quality of service (QoS) is valuable in streaming applications. By utilizing the information from QoS measurements, the video traffic can be adapted to meet the constraints on the network transmission which improves the perceived playback quality. The endeavor of the research is to review the concept of QoS, to study different QoS monitoring approaches and to construct a system that monitors the experienced end-to-end QoS of several simultaneous video streaming sessions. The research is based on the constructive method of the related publications and technologies and the results are derived by the constructed end-to-end QoS monitoring system.
