MPEG VIDEO TRAFFIC ON A METARING NETWORK - COMPLEXITY REDUCTION OF A WORST-CASE MODEL FOR BANDWIDTH ALLOCATION ANALYSIS

This paper deals with the problem of selecting the optimal bandwidth a llocation scheme for MPEG video transport on a MetaRing network. The p roblem is addressed by analyzing a simplified 'worst-case' network mod el faded by an MPEG video traffic model which only captures short rang e correlations. To assess to what extent the video traffic model still provides useful information, a methodology based on the busy-time dis tribution of the buffer is introduced. According to this methodology, the MPEG video traffic model still provides accurate results until the portion of bandwidth allocated to each MPEG video source is greater t han or equal to 50% of the peak rate.
