CSCuh75537 - Congestion Control Threshold and TCA Alerts
Feature Changes
SaMOG Congestion Control and Threshold Crossing Alerts (TCA) Support
With this release, SaMOG enhances on the StarOS framework to provide congestion control policies and threshold
crossing alerts to ensure smooth performance of the SaMOG service and prevent congestion. This feature enables you to
set policies and thresholds, and specify how the system should react in the event of a heavy load condition. The StarOS
congestion control framework monitors the system performance and invokes configured policies in the event of a
degraded performance to handle it.

Licensing utilization
Maximum sessions per service utilization
Demux message queue utilization
Demux message queue wait time
Port Rx specific utilization
Port Tx specific utilization
Averate transmit port Tx utilization
Process CPU utilization
System CPU utilization
System memory utilization
The behavior of system under high load or overload conditions can be specified using Congestion control.
The TCA feature monitors a variety of internal resources and user traffic events. The threshold values for the monitored
resources and events can be configured, and the system generates an alarm when the threshold is exceeded.
