In this paper, we develop a queueing model for analyzing the statistical performance for B-ISDN using virtual path techniques. By comparison to simulation results, it is demonstrated that this model can predict the system performance well. The cell loss probability, and the statistics of burst cell loss due to network congestion are obtained. The results can be summarized as follows. First, extending queueing buffer can reduce the cell loss rate, but under heavy traffic load conditions, the improvement is insignificant. Second, coding combined with suitable queueing buffer sizes can significantly improve the performance suffering from the short term congestion and transmission errors. These results provides some of the information needed for the designs of error protection, flow control, and priority control.
