Task 11: Configuring quality of service
Attribute Meaning
Uplink Burst
Allocation
Specify the maximum amount of data to allow each SM to
transmit before being recharged at the Sustained Uplink
Data Rate with credits to transmit more. See Maximum
Information Rate (MIR) Parameters on page 154

Settings on page 156

Max Burst Downlink
Data Rate
These parameters allow operators to specify the data rate at
which a SM is allowed to transmit (until burst allocation limit is
reached) before being recharged at the Sustained Downlink
Data Rate with credits to transit more. When set to 0 (default),
the burst rate is unlimited.
Sustained Downlink
Data Rate
Specify the rate at which the AP is replenished with credits
(tokens) for transmission to each of the SMs in its sector.
This default imposes no restriction on the uplink. See

Downlink Burst
Allocation
Specify the maximum amount of data to allow the AP to transmit
to any registered SM before the AP is replenished with
transmission credits at the Sustained Downlink Data Rate.

Broadcast Downlink
CIR
Broadcast Downlink CIR (Committed Information Rate, a
minimum) supports system designs where downlink broadcast is
desired to have higher priority than other traffic. For many
other system designs, especially typical internet access
networks, leave the Broadcast Downlink CIR at the default.
Broadcast Downlink CIR is closely related to the Broadcast
Repeat Count parameter, which is settable in the Radio tab of
the Configuration page in the AP: when the Broadcast Repeat
Count is changed, the total of available bandwidth is also
changed, since packets are being sent one, two, or three times,
according to the setting in the Broadcast Repeat Count
parameter.
Priority Precedence Allows operator to decide if 802.1p or DiffServ priority bits must
be used first when making priority decisions.
