Rate Limiting Configuration Sets

Rate Limiting Configuration Sets provide the mechanism to enter data needed by Egress Throttle Groups (on the SOAM GUI) and Egress Throttle Lists (on the NOAM GUI) to perform egress throttling by egress message rate. For details about the NOAM functionality, see Rate Limiting Configuration Sets on the NOAM.

You can perform these tasks on an Active System OAM (SOAM).

An Egress Throttling Group is always associated with a Rate Limiting Configuration Set, which provides the following data for performing Egress Message Rate Throttling:

• Maximum Message Rate
• Onset and Abatement Thresholds:
  • Percentages of the maximums
  • Used with Message Priority to determine which requests to throttle
• Convergence time, which allows you to control the sensitivity of request traffic bursts on an ETG.
• Abatement time

Rate Limiting can be enabled on the SOAM Main Menu: Diameter > Maintenance > Egress Throttle Groups page.

For NOAM functionality, you must change the Egress Throttling Control Scope of the Egress Control Group to ETL and enable Egress Message Rate Throttle on the Egress Throttle Group before Egress Message Rate Throttling can be started on Egress Throttle Lists.

The Rate Limiting Configuration Set fields are described in Rate Limiting Configuration Sets elements.

On the Rate Limiting Configuration Sets page, you can perform the following actions:

• Filter the list of Rate Limiting Configuration Sets to display only the desired Rate Limiting Configuration Sets.
• Sort the list by column contents in ascending or descending order by clicking the column heading. The default order is by Rate Limiting Configuration Set Name in ascending ASCII order.
• Click Insert.

  On the Rate Limiting Configuration Sets [Insert] page, you can add a new Rate Limiting Configuration Set. See Adding a Rate Limiting Configuration Set.

  If the maximum number of Rate Limiting Configuration Sets already exists in the system, an error message displays.

• Select a Rate Limiting Configuration Set Name in the list and click Edit.

  On the Rate Limiting Configuration Sets [Edit] page, you can edit the selected Rate Limiting Configuration Set. See Editing a Rate Limiting Configuration Set.

  If no row is selected, or if more than one row is selected, Edit is disabled.

• Select a Rate Limiting Configuration Set Name in the list and click Delete to remove the selected Rate Limiting Configuration Set.

  The Default Rate Limiting Configuration Set can be edited, but cannot be deleted. See Deleting a Rate Limiting Configuration Set.
