Functional Description
WRED proceeds in this order when a packet arrives:
- Calculation of the average queue size.
- The arriving packet is queued only if the average queue size is below the minimum queue threshold.
- Depending on the packet drop probability the packet is either dropped or queued if the average queue size is between the minimum and maximum queue threshold.
- The packet is automatically dropped if the average queue size is greater than the maximum threshold.

Famous quotes containing the words functional and/or description:
“Stay-at-home mothers, . . . their self-esteem constantly assaulted, . . . are ever more fervently concerned that their offspring turn out better so they won’t have to stoop to say “I told you so.” Working mothers, . . . their self-esteem corroded by guilt, . . . are praying their kids turn out functional so they can stop being defensive and apologetic and instead assert “See? I did do it all.””
—Melinda M. Marshall (20th century)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
