random drop is conducted when the amount of tokens for a traffic stream falls below the set threshold for wireless
client traffic.
Background Traffic
Best Effort Traffic
Set a percentage value for WLAN 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.
Select the Enable radio button to enable rate limiting for data transmitted
from access point radios to associated clients. Enabling this option does
not invoke rate limiting for data traffic in the downstream direction. This
feature is disabled by default.
Define an upstream rate limit between 50 - 1,000,000 kbps.This limit
constitutes a threshold for the maximum the number of packets
transmitted or received from clients (from all access categories). Traffic
exceeding the defined rate is dropped and a log message is generated. The
default setting is 1000 kbps.
Set a maximum burst size between 2 - 1024 kbytes. The smaller the burst,
the less likely the upstream 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.
Upstream Random Early Detection Threshold
Set a percentage value for client background traffic in the upstream
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 upstream 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 upstream direction. This
is a percentage of the maximum burst size for normal priority 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 upstream rate is known by the
network administrator (using a time trend analysis). The default threshold
is 50%.
