QoS Overview
The system attempts to find the best operational rate depending on the defined constraint. The
supported constraints are listed below:
•
•
•
Hardware supports rates to be in the multiple of 8 kbps, the system will attempt to find the best
operational rate depending on the defined constraint. The supported constraints are:
•

specified in the CLI.
Table 13: Administrative Rate Example
Administrative Rate
If user has configured any value greater than 0 and less than 8 then operation rate configured on
hardware would be 8 kbps irrespective of the constraint used.
Note: The burst size configured by the user affects the rate step-size used by the system. The
system uses the step size in a manner that both the burst-size and rate parameter constraints are
met. For example, if the rate specified is less than 4Gbps but the burst size configured is 17Mbits,
then the system uses rate step-size of 16Kbits and burst step-size of 8192bits (refer to
row#2)
Committed Burst Size
The committed burst size parameter specifies the maximum burst size that can be transmitted by
the source at the CIR while still complying with the CIR. If the transmitted burst is lower than the
Page 40
Minimum: Find the next multiple of step-size that is equal to or greater than the specified
rate.
Maximum: Find the next multiple of step-size that is equal to or less than the specified
rate.
Closest: Find the next multiple of step-size that is closest to the specified rate.
Minimum: Find the next multiple of 8 kbps that is equal to or higher than the specified
rate.
Maximum: Find the next multiple of 8 kbps that is equal to or less than the specified rate.
Closest: Find the next multiple of 8 kbps that is closest to the specified rate.
