RED Drop Probability Function

The following illustration shows the drop probability function with associated parameters.

Max. DP 1-3 is the drop probability when the average queue filling level is 100%. Frames marked with Drop Precedence Level 0

are never dropped. Min. Threshold is the average queue filling level where the queues randomly start dropping frames. The

drop probability for frames marked with Drop Precedence Level n increases linearly from zero (at Min. Threshold average queue

filling level) to Max. DP n (at 100% average queue filling level).
