EFFECTS OF DUAL LEAKY BUCKET PARAMETERS ON CELL LOSS RATIO - WORST-CASE ANALYSIS

Leaky Bucket based traffic parameters are widely used for traffic decl aration and enforcing in an ATM network. In this paper, we investigate the characteristics of the system that every traffic source is police d by a dual leaky bucket before entering the network. In addition to m ean cell rate, peak cell rate of traffic is also taken into considerat ion. We find the worst output pattern from the dual leaky bucket and d erive the performance bound of maximum cell loss ratio encountered in the multiplexer. It is obtained as every source transmits cells accord ing to the criteria for extreme synchronous transmission in a coincide nt token-generating condition.
