An application-driven approach to networked multimedia systems

Several architectural choices possible in logical multiplexing, accommodating QoS dynamics, and functional divisions between senders and receivers are discussed. The authors' application requirements favor integration rather than channelization, supporting quality of service (QoS) dynamics with a renegotiation mechanism, and pushing complexity towards receivers. The choices are tested via implementation of a telerobotics/teleoperation application. This application is particularly challenging due to its demand for multiple concurrent media streams with varied QoS requirements.
