Abstract

A new technique is developed to analyze the cell loss behavior of individual connections in finite intervals for ATM networks. The technique is applied to Partial Buffer Sharing (PBS) in deriving the cell loss rate and queue length distributions in finite intervals on a per cell class basis. To maximize network utilization and to reduce the fluctuation on cell loss probability, a new and more flexible cell loss control mechanism called Threshold-based Loss Balancing (TLB) is proposed. Unlike PBS, which protects the high priority cells only, TLB regulates the violation probability on each class of cells for each connection. Comparisons of TLB and PBS on selected operating conditions show that TLB can accommodate more connections given the same quality of service requirements than PBS.
