  • Multi-level ager rings for tracking session life cycle
    Patent number: 9871869
    Abstract: A device may determine a session life cycle associated with a communication session. The session life cycle may indicate a time period associated with expiration of the communication session. The device may compare the session life cycle and a threshold value, and may determine that the session life cycle satisfies the threshold value based on comparing the session life cycle and the threshold value. The device may initialize multiple ager rings based on determining that the session life cycle satisfies the threshold value. The multiple ager rings may be used to monitor the expiration of the communication session. The device may monitor the expiration of the communication session using the multiple ager rings.
    Type: Grant
