Double-Buffer Traffic Shaper Modelling for Multimedia Applications in Slow Speed Network

Lack of end-to-end quality-of-service support, unbounded packet-data delay, poorly adapted transport protocol and slow-speed network are factors militating against the deployment of realtime video streaming across the Internet at slow-speed. This paper presents a Double-Buffer Traffic Shaper (DBTS) for rate adaption of real-time video transmission in a slow-speed network using Transmission Control Protocol (TCP) for data transportation. The scheme was tested in Matlab and it was found to reduce variable bit rate (VBR) traffic burstiness to its barest minimum and variability to almost nil.
