Evaluation of token bucket parameters for VBR MPEG video

초록

Guarantees of quality-of-service (QoS) in the real-time transmission of video is a challenging task for the success of many video applications. To guarantee the QoS, it is necessary to provide traffic sources with the capability of calculating the traffic characteristics to be declared to the network on the basis of a limited set of parameters statistically characterizing the traffic and the required level of QoS. In this paper, we develop an algorithm for the evaluation of the traffic parameters which characterize the video stream when a QoS requirement is given. To this end an analytical traffic model for the VBR MPEG video is introduced. Simulation results show that the proposed method can evaluate the traffic parameters precisely and efficiently. © Springer-Verlag Berlin Heidelberg 2004.
