What are the correct terms of the following description of ECN high and low thresholds?

If the queue cache is higher than the high threshold, all packets are discarded

When the queue cache is above the high threshold, all ECN tokens are performed

The queue cache is above the low threshold but below the high threshold, and the closer it is to the high threshold, the higher the probability of tagging

When the queue cache falls below a low threshold, no ECN tagging is performed
