Neste artigo, propomos um método analítico para dimensionar descritores de tráfego no UPC baseado em leaky bucket para tráfego de vídeo VBR MPEG em redes ATM. Derivamos analiticamente as probabilidades de violação de células no UPC usando um modelo de tráfego de vídeo baseado em cena proposto e, em seguida, mostramos que era possível selecionar conjuntos de descritores de tráfego que produzissem a probabilidade de violação necessária. Em dois exemplos de traços de vídeo, os resultados numéricos mostraram que nosso método proposto de dimensionamento do descritor de tráfego se aproximou bem dos resultados de controle de tráfego baseados em simulação dos traços de vídeo reais. Nos casos em que foi utilizado um método de alocação efetiva de largura de banda baseado no modelo ON/OFF para o controle de admissão de chamadas nas redes, comparamos a largura de banda efetiva alocada para cada conjunto de descritores de tráfego que produziu zero perdas de UPC.

Abstract: In this paper, we propose an analytic method for dimensioning traffic descriptors at the leaky bucket-based UPC for VBR MPEG video traffic on ATM networks. We analytically derived cell violation probabilities at the UPC by using a proposed scene-based video traffic model, and then we showed that it was possible to select sets of traffic descriptors that produce the required violation probability. In two example video traces, the numerical results showed that our proposed traffic descriptor dimensioning method well approximated the simulation-based traffic control results of the real video traces. In cases where an effective bandwidth allocation method based on the ON/OFF model was used for the call admission control in the networks, we compared the allocated effective bandwidth to each set of traffic descriptors that produced zero UPC losses.
