The transmission of stored video across an ATM network is considered for interactive applications with bounded reaction times. The performance of the services renegotiated VBR (RVBR) and renegotiated CBR (RCBR) is investigated for this class of applications by trace-driven simulations. The goal is to determine the most efficient service for interactive applications. Here we present three basic results. First, for delay sensitive applications smoothing the video stream in advance is much more efficient than adding smoothing buffers to the network switches. Second, services with renegotiation (RCBR, RVBR) are better suited for interactive applications than the static services CBR and VBR. Third, the RVBR service with a deterministic call admission control scheme is the best choice for interactive applications that require small reaction times. [ABSTRACT FROM AUTHOR] |
