Off-line bandwidth smoothing with adaptive-segmented traffic

Bandwidth smoothing can effectively increase the utility of the network bandwidth with reducing the bursting of the traffic. Making use of the trend of the changing of the play traffic around the average rate line, an adaptive-segmented smoothing algorithm was proposed in this paper, which can reduce the buffer required of the client. The traffic smoothing result on the analysis function showed the buffer size required by the algorithm is less half than that of the PCRTT. In the following experiment, the MPEG4 movie was used for comparing the performance of the variable smoothing algorithms. The results demonstrate that the PCRTT and the e-PCRTT after using adaptive segment outperform the before with the same number of the segments for the burst movie.
