FDDT+: improving fairness for video transmission over IP networks

Traditional buffer management techniques, which are based on reducing packet loss, fail to ensure user expected video quality. In www3.informatic.uni-wuerzburg.de, we proposed an alternative buffer management approach, called FDDT, which focuses on controlling packet loss distribution. Experiments have shown that FDDT significantly improves both video quality and network efficiency. As an extension of FDDT, in this paper, we address fairness with respect to different video streams and introduce a new buffer management scheme called FDDT+. Performance evaluation of the FDDT+ scheme is presented.
