7.58 Committed Burst Size (kbyte) (CAR Configuration)

Description
The Committed Burst Size (kbyte) (CAR Configuration) parameter specifies the maximum
guaranteed data volume of a flow, which can be transmitted within a certain period.
Impact on the System
After the CAR is enabled and bound with a flow, if the volume of burst data in the flow is less
than the value of Committed Burst Size (kbyte), the burst data can be guaranteed for
transmission. Otherwise, they cannot be guaranteed for transmission.

0-32
Configuration Guidelines
Based on the actual requirements of QoS, you can set a proper value for Committed Burst Size
(kbyte).
Generally, the value of Committed Burst Size (kbyte) is not less than the possible size of
expected burst data flow to be transmitted.
Relationship with Other Parameters
You can set Committed Burst Size (kbyte) of a CAR only after creating the CAR.

7.59 Peak Information Rate (kbit/s) (CAR Configuration)

Description
The Peak Information Rate (kbit/s) (CAR Configuration) parameter specifies the peak
information rate (PIR) of the committed access rate (CAR). It specifies the allowed maximum
rate of a flow.
Impact on the System
After the CAR is enabled and bound with a flow, the flow rate is limited according to the peak
bandwidth of the CAR parameter.
If the traffic volume is greater than the value of Peak Information Rate (kbit/s), the excessive
traffic is discarded.
