Abstract

This paper deals with the problem of selecting the optimal bandwidth allocation scheme for MPEG video transport on a MetaRing network. The problem is addressed by analyzing a simplified 'worst-case' network model faded by an MPEG video traffic model which only captures short range correlations. To assess to what extent the video traffic model still provides useful information, a methodology based on the busy-time distribution 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 than or equal to 50% of the peak rate.
