ABSTRACT:
Methods of traffic smoothing for frames of different video sources where each video source transmits frames at fixed intervals and the network is free to decide the relative temporal spacing of video frames from different sources provide significant performance advantages. The time at which a given source begins to transmit its first frame is under the control of the network; however, thereafter, all frames from the source are transmitted at fixed intervals. Two heuristic and one optimization method control the temporal placement of the video frames from different sources in order to reduce the loss rate of the high priority cells and to minimize the smoothness index of the traffic.
