Application-layer QoS control and testing method for audio/video delivery over space network
空间通信网中音视频传输的应用层QoS控制与测试方法

We analyze the interconnection among WLAN, Internet, and Ku-band satellite communication networks. In order to meet the QoS requirements of the audio/video delivery, we have proposed an application-layer QoS control and testing method by using a frame rate and resolution adaptive modification algorithm. The simulation results show that the proposed method enhances the network utilization rate and has great QoS control capability of modifying the frame rate adaptively.
