DYNAMIC BEHAVIOR ANALYSIS OF CELL LOSS CONTROL MECHANISMS IN ATM NETWORKS

A new technique is developed to analyze the cell loss behavior of indi vidual 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 fluctua tion on cell loss probability, a new and more flexible cell loss contr ol 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 servic e requirements than PBS.
