Sabe-se que as características da taxa de perda de células (CLR) do tráfego multiplexado dependem do arranjo dos tempos de início da imagem I de fontes de vídeo MPEG de taxa de bits variável (VBR) individuais. Neste artigo, propomos um modelo de tráfego simples, porém preciso, para o vídeo VBR MPEG multiplexado para calcular o CLR em um multiplexador ATM quando o arranjo dos tempos de início da imagem I de fontes individuais é fornecido. No modelo proposto, para representar o arranjo dos tempos de início da imagem I, cada tipo de imagem (imagem I, P ou B) da fonte individual é modelado pelo histograma da taxa de chegada e pelo tráfego de vídeo multiplexado. é modelado pela convolução dos histogramas de taxas de chegada das imagens que compõem o tráfego multiplexado. Utilizando o modelo de tráfego proposto, propomos um método analítico para calcular o CLR do vídeo VBR MPEG multiplexado em um multiplexador ATM. Os resultados da simulação mostram que o método proposto pode calcular o CLR de forma mais precisa e eficiente do que outros métodos existentes.

Abstract: It has been known that the cell loss ratio (CLR) characteristics of the multiplexed traffic depend on the arrangement of I-picture starting times of individual variable bit rate (VBR) MPEG video sources. In this paper, we propose a simple yet accurate traffic model for the multiplexed VBR MPEG video to calculate the CLR at an ATM multiplexer when the arrangement of the I-picture starting times of individual sources is given. In the proposed model, in order to represent the arrangement of the I-picture starting times, each picture type (I-, P-, or B-picture) of individual source is modeled by the arrival rate histogram, and the multiplexed video traffic is modeled by the convolution of the arrival rate histograms of the pictures that comprise the multiplexed traffic. Using the proposed traffic model, we propose an analytical method to calculate the CLR of the multiplexed VBR MPEG video at an ATM multiplexer. Simulation results show that the proposed method can calculate the CLR more precisely and efficiently than other existing methods.
