The multiplex weight and random fuzzy rules adjustment method in the system architecture are introdued. The conclusions show that the FAMLB is a better dynamic method of UPC than the traditional ones.展开更多

The performance of leady bucket algorithm with bursty traffic input is analyzed. The influences of various parameters on QOS (Quality of Service) are investigated. The analysis shows that although the loss probability decreases through expanding the buffer capacity, the delay and delay jitter increase, whose effect on QOS will not be negligible.展开更多
