Congestion Options are configurable on Active NOAM servers.
The Congestion Options can be configured:
- Alarm Thresholds, which are used to:
- Set the percentage of the Policy and Charging ingress message rate capacity at which an alarm is raised with Critical, Major, or Minor severity.
- Set the percentage of the Policy and Charging ingress message rate capacity at which a Critical, Major, or Minor severity alarm is cleared.
The percentages control the onset and abatement of the corresponding Congestion Levels.
Default thresholds are based n the engineered system value for Ingress Policy and Charging Request Message Capacity.
- Message Throttling Rules, which determine the percentage of Session Creation, Update, and Terminate Request messages that are discarded when Congestion Levels 1, 2, and 3 exist.
The fields are described in Congestion Options elements.
