Defining random early detection
The command
random-detect
TCP transfers that last longer than simple web requests, there is a risk that TCP flow-control might be ineffi-
cient. A burst-tolerance index between 1 and 10 may optionally be specified (exponential filter weight). The
form of this command reverts the queue to default "tail-drop" behavior.
Mode: Source
node (src)[ name ]#random-detect { burst-tolerance }

Discarding Excess Load

The command controls traffic arriving in a queue for class name. The value of the first argument aver-
police
age-kilobits defines the average permitted rate in kbps, the value of the second argument kilobits-ahead defines
the tolerated burst size in kbps ahead of schedule. Excess packets are dropped.

Defines random early detection (RED) for
queues of for the selected traffic-class or policy
name . The range for the optional value burst-
tolerance is from 1 to 10.
Defines how traffic arriving in a queue for the selected
class or policy name has to be controlled. The value aver-
age-kilobits for average rate permitted is in the range
from 0 to 10000 kbps. The value kilobits-ahead for burst
size tolerated ahead of schedule is in the range from 0 to
10000.
