Duas características principais do tráfego de vídeo VBR MPEG são as diferentes estatísticas de acordo com os diferentes tipos de imagem e o padrão de tráfego periódico devido à estrutura GOP. Especialmente, as imagens I no início de cada GOP geram muito mais tráfego do que outras imagens. Portanto, quando diversas fontes de vídeo VBR MPEG são sobrepostas, o desempenho da multiplexação pode variar de acordo com as variações dos tempos de início da imagem I. Neste artigo, mostramos como o arranjo do tempo de início dos vídeos VBR MPEG sobrepostos pode afetar significativamente as características da taxa de perda de células nos multiplexadores, usando o modelo de filas U-NDPP/D/1/B. Também é mostrado que a distribuição Lognormal é mais adequada para modelar o tráfego de vídeo VBR MPEG do que as distribuições Normal e Gama, nos pontos de vista da aplicação de filas.

Abstract: Two main characteristics of VBR MPEG video traffic are the different statistics according to different picture types and the periodic traffic pattern due to GOP structure. Especially, the I-pictures at the beginning of each GOP generate much more traffic than other pictures. Therefore, when several VBR MPEG video sources are superposed, the multiplexing performance can vary according to the variations of their I-picture start times. In this paper, we show how the start time arrangement of the superposed VBR MPEG videos can significantly affect the cell loss ratio characteristics at the multiplexers, by using U-NDPP/D/1/B queueing model. It is also shown that the Lognormal distribution is more suitable for modeling VBR MPEG video traffic than the Normal and Gamma distributions, in the queueing application's view points.
