The early discard strategy will calculate the drop probability based on the BLUE
algorithm, which uses packet loss and link utilization history to manage congestion.
BLUE maintains a single probability, which it uses to mark (or drop) packets when
they are queued. If the queue is continually dropping packets due to buffer overflow,
BLUE increments the marking probability, thus increasing the rate at which it sends
back congestion notification. Conversely, if the queue becomes empty or if the link is
idle, BLUE decreases its marking probability.
Description
The reserved subqueue size in kilo bytes (KB).
This has the same function as the respackets
parameter but uses size in kilo bytes instead of
packets.
Description
The hold time in microseconds for early discard
strategy.
Description
The maximum packet marking probability in parts per
mille for early discard strategy.
