Analysis of MPEG-1 transmission through B-ISDN ATM networks

Abstract

To understand the performance of MPEG-1 videos when transmitted through B-ISDN ATM networks, this paper analyzes an equivalent simulated network. Allocation of network bandwidth is based on equivalent capacity with MMBP inputs providing background traffic. Cell losses are examined and found to be near target. Also, an analysis of cell delay indicates that delay distributions can be approximated by gamma distributions and that frame-to-frame cell delay is uncorrelated for the test network. Finally, a method to predict MPEG-1 decode buffer underruns is developed and validated.
