Usage Information If the average queue size is more than the maximum threshold of WRED, the packet is
dropped. If the average queue size is between the minimum and maximum threshold
values, the decision to drop or queue the packet is taken based on the packet drop
probability. The probability that a packet is dropped depends on the minimum
threshold, maximum threshold, and mark probability denominator.
