RED Drop Probability Function
Min is the fill level where the queue randomly start dropping frames marked with Drop
Precedence Level > 0 (yellow frames).
If Max Unit is 'Drop Probability' (the green line), Max controls the drop probability when the fill
level is just below 100%.
If Max Unit is 'Fill Level' (the red line), Max controls the fill level where drop probability reaches
100%. This configuration makes it possible to reserve a portion of the queue exclusively for frames
marked with Drop Precedence Level 0 (green frames). The reserved portion is calculated as (100 -
Max) %.
Frames marked with Drop Precedence Level 0 (green frames) are never dropped.
The drop probability for frames increases linearly from zero (at Min average queue filling level) to
Max Drop Probability or Fill Level.
