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.
