The SBC calculates the packet loss rate as (number of packets lost
/number of packets expected
) x 100
.
For every incoming call leg:
- The SBC periodically (approximately after every 512 expected packets) calculates the packet loss rate.
- The SBC also periodically (approximately after every 10 seconds) checks if the packet loss rate of the call is above the configured value for the parameter
Packet Loss Threshold
. - If the SBC detects that the loss rate has exceeded the threshold, it reports the difference to higher layer of services within the software stack.
