The Consideration of the Sending Host Timing Drift Problem in Streaming Real-time Communication

Abstract

With the successful of the Internet and the use of broadband in homes, the traffics on the Internet are being shifted from data to multimedia communication. For reducing the buffer requirement on the client side and the service request/response time, streaming technology is normally adopted to handle the transmission of multimedia traffic. This work investigates the timing drift problem of the sending host in streaming communication and applies an adaptive rate control mechanism in cooperation with a client feedback packet to prevent stream buffer overflow or underflow. To reduce the network overhead of the feedback mechanism, a sending host self-timing revision scheme is used.
