Configuring Back-off and Jitter Timers in DNN Profile

To define values for the back-off and jitter timers in DNN profile, use the following sample configuration:

config 
   profile dnn dnn_profile_name 
      timeout backoff backoff_timer_value 
      timeout jitter jitter_timer_value 
      end 

NOTES:

  • timeout backoff backoff_timer_value : Specify the back-off timer value, in seconds. backoff_timer_value must be an integer in the range of 0-576000.

    The back-off timer is the maximum allowed duration used during IP exhaustion and N4 path failure cases.

  • timeout jitter jitter_timer_value : Specify a jitter value to introduce randomness in the back-off timer value. jitter_timer_value must be an integer in the range of 0-1000.

    The jitter allows spreading the different backoff timers to the UE devices so that they all wait at different times before the next reconnection attempt.

    This configuration helps to prevent a session storm after the back-off timer expiry.

The following is an example configuration used during N4 path failure scenarios.

config 
   profile dnn test 
      timeout backoff 200 jitter 50 
      end
