DDRS Rate Incr RTX
Threshold
Represents a threshold for the percentage of retransmissions, below which the rate can be
increased. By default, it is set to 25%.
: If the percentage of retransmissions is between “Rate Increment RTX Threshold”
and “Rate Decrement RTX Threshold” then the current operation rate is
maintained.
DDRS Rate Decr RTX
Threshold
Represents a threshold for percentage of retransmissions, above which the rate can be
decreased. By default, it is set to 30%. Please note that if the percentage of
retransmissions is between “Rate Increment RTX Threshold” and “Rate Decrement RTX
Threshold” then the current operation rate is maintained.
DDRS Chain Balance
Threshold
In the case of MIMO, the difference in SNR between two chains must be less than or equal
to this threshold for the chains to be considered as “Balanced”. By default, it is set to 15
dB.
:
·
This parameter is applicable only in Auto stream mode.
·
When Auto stream mode is configured and if chains are not balanced, then
Single Stream rates are considered.
DDRS Rate Back Off
Interval
DDRS algorithm constantly attempts higher data rates, when the current rate is stable. If
not successful, it goes back to older stable rate. Before the next attempt, it waits for a
minimum duration. This duration starts with 10 seconds and increases exponentially up to
Rate Back Off Interval and remains at this value. By default, it is set to 300 seconds.
DDRS Rate Blacklist
Interval
Applicable when data stream mode is set to Auto.
DDRS algorithm dynamically determines the performance of the single and dual stream
data rates independently and blacklists unviable data rates to avoid unnecessary
fluctuations, for a period of DDRS Rate Blacklist Interval. By default, it is set to 600
seconds.
: DDRS Rate Back Off Interval must be less than the DDRS Rate Blacklist Interval.
DDRS Rate Stable
Interval
DDRS algorithm attempts higher data rates only when the current data rate is stable for a
period of DDRS Rate Stable Interval. By default, it is set to 10 seconds.
