摘要 分析了无线局域网、因特网和Ku频段卫星通信网的互联互通及服务质量(QoS)性能参数,采用视频帧率、分辨率自适应算法,提出了一种空间通信网中音视频传输的应用层QoS控制与测试方法.仿真实验结果表明,该方法提高了网络利用率,并具有良好的QoS自适应帧率调整能力. 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.
