Abstract :
The leaky bucket (LB) access control scheme has been widely proposed as the usage parameter control (UPC) mechanism at the user-network interface (UNI) for B-ISDN. An important goal for any UPC scheme is that it be able to accommodate a wide range of services. In this paper, we investigate the performance of the LB as an access control mechanism for transmission of variable bit rate (VBR) MPEG video. In particular, we focus on the following issues: 1) the requirements for lossless video transmission, 2) the trade-offs between token pool size and token regeneration rate, 3) the effect of traffic smoothing and 4) the performance of different encoded video sequences. Finally, we present a new technique for VBR video transmission using multiple LB´s and we discuss the advantages of this techniques when cell losses occur
