Simulation results show that FLB algorithm is better than LB in some aspects of lowering cell loss probability, improving delay and delay jitters, and utilizing efficiency of resource.

The paper proposes an improvement of Leaky Bucket Technique. The basic idea is to decrease the cell losing ratio by adding an input buffer.

Through the computer simulation, a quantitative analysis is given about the influence that the modified model brings to the cell losing ratio, the cell average delay and the average delay variance.
