Set a maximum burst size from 2 - 1024 kbytes. The smaller the burst, the less likely the
downstream packet transmission will result in congestion for wireless client traffic. By
trending the typical number of ARP, broadcast, multicast and unknown unicast packets
over a period of time, the average rate for each access category can be obtained. Once a
baseline is obtained, administrators should then add a minimum of a 10% margin to allow
for traffic bursts at the site. The default burst size is 64 kbytes.
Downstream Random Early Detection Threshold
Set a percentage for client background traffic in the downstream direction. This is a
percentage of the maximum burst size for low priority traffic. Background traffic exceeding
the defined threshold is dropped and a log message is generated. Background traffic
consumes the least bandwidth of any access category, so this value can be set to a lower
value once a general downstream rate is known by the network administrator (using a
time trend analysis). The default threshold is 50%.
Set a percentage for client best effort traffic in the downstream direction. This is a
percentage of the maximum burst size for normal traffic. Best effort traffic exceeding the
defined threshold is dropped and a log message is generated. Best effort traffic consumes
little bandwidth, so this value can be set to a lower value once a general downstream rate
is known by the network administrator (using a time trend analysis). The default threshold
is 50%.
Set a percentage for client video traffic in the downstream direction. This is a percentage
of the maximum burst size for video traffic. Video traffic exceeding the defined threshold
is dropped and a log message is generated. Video traffic consumes significant bandwidth,
so this value can be set to a higher value once a general downstream rate is known by the
network administrator (using a time trend analysis). The default threshold is 25%.
Set a percentage for client voice traffic in the downstream direction. This is a percentage
of the maximum burst size for voice traffic. Voice traffic exceeding the defined threshold
is dropped and a log message is generated. Voice applications consume significant
bandwidth, so this value can be set to a higher value once a general upstream rate is
known by the network administrator (using a time trend analysis). The default threshold is
0%. 0% means no early random drops will occur.
