    The paper considers the problem of rendering post production applications in a distributed environment. The aim is to limit the concessions that conventional, in-house methods force graphics operators to make to the quality of the end products to get them on time and within budget. A reference architecture for distributed rendering is proposed that takes advantage of the parallel properties of the... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (380 KB)

    We are concerned about the problem of transmitting constant quality video over the B-ISDN. A gain in channel utilization is achieved when several variable bit rate video sources share a common ATM connection. To achieve such gain, the impact of cell losses on video quality degradation should be considered. Multi-layered video coding has been shown to tolerate more cell losses than non-layered vide...

    Data filtering is a semantic-based technique that can significantly reduce the size of traffic in large-scale distributed interactive simulation (DIS) networks. If not carefully designed, filtering algorithms could lead to errors that may compromise the realism of the training exercise. The authors review the problem of filtering errors and present an approach suitable for preventing filtering err... View full abstract»

    Consider m offices with each operating a duplexed unit. Suppose a centrally located warehouse is to be provisioned with k spares to be used when offices experience failures. Assume that failed units are instantaneously replaced with spare units, provided a spare is available at the warehouse and the failed units are repaired and used to replenish the spare inventory. We consider two approaches for... View full abstract»

    An analytic model is presented for a partially reliable transport protocol based on retransmissions. The model illustrates tradeoffs between two QoS parameters (delay and throughput), and various levels of reliability. The model predicts that the use of a reliable transport service when an application only needs a partially reliable one causes considerable throughput decreases and delay increases ...

    The emphasis in the paper is on the traffic control at an ATM end source. The purpose of locally controlling a source is the improvement of the TCP performances over ATM. The authors argue the need of a policing mechanism less stringent than the generic cell rate algorithm proposed by the ITU. A more flexible method which is suitable for providing performance guarantees in high speed networks is p... View full abstract»
