Specifies the congestion level at which the adaptive congestion control algorithm activates. The adaptive algorithm iteratively adjusts the call acceptance rate up or down to maximize call throughput while maintaining target performance metrics throughout the overload event. The algorithm is self-tuning to automatically adjust to the SBC nominal capacity (and to non-call-rate related events consuming unpredictable amounts of CPU) and is independent of call scenario mix, signaling types, and user retry behavior. There is a single default configuration for all system configurations. Emergency calls may optionally be given preference over non-priority calls.

On SBC main screen, go to All > System > Congestion > Adaptive.

Description

MCLevelSets the system machine congestion level at which the system adaptive algorithm activates:
  • mc1 – Adaptive congestion control is activated at system congestion level mc1.
  • mc2 – Adaptive congestion control is activated at system congestion level mc2.
  • mc3 – Adaptive congestion control is activated at system congestion level mc3.
