Abstract�� The BEST-EFFORT internet can't meet such quality of service (QoS) requirements as bandwidth, latency, and loss of real-time video applications, so the application layer QoS control strategies, congestion control and error control, are widely used. A joint transport framework of real-time video that supports application layer QoS was presented. This framework involves not only network resources and their variations, but also the restrictions of QoS control on the video quality of perception (QoP). The fuzzy map from QoS to QoP is also considered to control the QoS more efficiently. As a result, this framework is promising to improve video application QoS on the BEST-EFFORT internet.
