PERFORMANCE EVALUATION OF AN ATM CONNECTION WITH SEVERAL CELL FLOW COMPONENTS

This letter studies the Peak Cell Rate (PCR) policing of ATM connectio ns that consist of multiple cell flow components. It is shown that the conventional methods proposed for policing the aggregate flow do nor use the network's resources efficiently. This Letter proposes a simple and efficient UPC (Usage Parameter Control) mechanism based on a tand em leaky bucket for multi-component ATM connections. The results show that network resource requirements can be minimized, with reasonable h ardware complexity.
