Congestion Commands

The

Spacevars
0series4
detects congestion by monitoring a time-decaying average of the CPU utilization. It also monitors the Internal Round-Trip Time (IRTT) during call setup for determining whether the
Spacevars
0product
is in congestion. When congestion (for either reason) is detected and the congestion level reaches MC2, the SBC activates a control algorithm which adaptively throttles calls to eliminate the congestion while still maximizing the call throughput.

On SBC main screen, go to All > System > Congestion. The Congestion window is displayed. The Congestion Commands panel appears at the bottom
