|Summary||In this paper, a CBR transport scheme for VBR MPEG-2 video-on-demand traffic in ATM networks is proposed. The basic idea is to smooth the VBR traffic to match a given bandwidth. In order to keep the continuous playback of the video, our scheme requires a suitable amount of buffer space at the receiver side and introduces an initial playback delay. We study these two performance measures as functions of allocated bandwidth. For given buffer size and bandwidth, it is sometimes necessary to control the transmission in order to satisfy the required QoS. Two control methods are examined and the corresponding minimum buffer requirements for the given QoS and bandwidth are investigated.|
