In video streaming, quality of service (QoS) guarantee is an im- portant issue. Algorithms used for scheduling play a major role in providing QoS. This paper describes QoS such as loss rate, delay-jitter and throughput in video streaming and their method of evaluation. A simulation environment has been designed combining network simulator, ns2 with video codec to predict the QoS. The scheduling algorithms such as the weighted round robin (WRR) and deficit round robin (DRR) have been applied and the performance metrics are evaluated and compared.
