摘　　要：标准化卫星多媒体传输的实现给予用户极大的便利。为了充分考虑实时多媒体流量,资源管理需要最大限度地利用有限的上行容量。为解决容量问题,本文提出了一个完整的卫星多媒体传输QoS架构,该架构是通过仿真平台实现,并通过实时多媒体应用程序进行评估。在QoS体系结构中发出的信号使用户能够通过QoS代理和QoS服务器应用程序实时更改其应用程序的QoS。The implementation of a standardized satellite multimedia transmission provides a user with great convenience.In order to take full account of real-time multimedia traffic,resource management needs to maximize the use of limited upstream capacity.In order to solve this capacity problem,this paper has proposed a full satellite multimedia transmission QoS architecture,which is achieved through the simulation platform,and is evaluated through real-time multimedia applications.The signal in QoS architecture allows users to change their application’s QoS in real time through QoS agent and QoS server applications.
