Abstract

A computer implemented method, a computer program product and a data processing system for reducing communication signaling protocol latency is provided. Automatic memory management activities, also known as garbage collection activities, are optimized based on a specified level of latency.

Claims

1. A computer implemented method for reducing communication signaling protocol latency, the computer implemented method comprising:

optimizing automatic memory management activities based on a specified level of latency.

2. The computer implemented method of claim 1, wherein the specified level of latency is a maximum amount of latency.

3. The computer implemented method of claim 1, wherein the specified level of latency is an average of an amount of latency.

4. The computer implemented method of claim 1, wherein the communication signaling protocol is a session initiation protocol.

5. The computer implemented method of claim 1, wherein optimizing automatic memory management activities based on a specified level of latency further comprises:

determining if an automatic memory management background thread is operating within specific parameters; and

responsive to a determination that the automatic memory management background thread is not operating within specific parameters, throttling acceptance of requests.

6. The computer implemented method of claim 5, wherein a request comprises a request to start a new communication session.

7. The computer implemented method of claim 5, wherein a request comprises an indiscriminate request.

8. The computer implemented method of claim 1, wherein optimizing automatic memory management activities based on a specified level of latency further comprises:

determining if an average automatic memory management activity time is above a specified threshold; and

responsive to a determination that the average automatic memory management activity time is above a specified threshold, throttling acceptance of requests.

9. The computer implemented method of claim 1, wherein the step of optimizing automatic memory management activities based on a specified level of latency is based on current statistics.

10. The computer implemented method of claim 1, wherein the step of optimizing automatic memory management activities based on a specified level of latency is based on predicted future automatic memory management needs.

11. The computer implemented method of claim 1, wherein the automatic memory management activity is a garbage collection activity.

12. The computer implemented method of claim 11, wherein optimizing automatic memory management activities based on a specified level of latency further comprises:

determining if an average garbage collection activity time is above a specified threshold; and

responsive to a determination that the average garbage collection activity time is above a specified threshold, throttling acceptance of requests.

13. A computer program product comprising a computer usable medium including computer usable program code for reducing communication signaling protocol latency, the computer program product comprising:

computer usable program code for optimizing automatic memory management activities based on a specified level of latency.

14. The computer program product of claim 13, wherein the specified level of latency is a maximum amount of latency.

15. The computer program product of claim 13, wherein the specified level of latency is an average of an amount of latency.

16. The computer program product of claim 13, wherein the communication signaling protocol is a session initiation protocol.

17. The computer program product of claim 13, wherein the computer usable program code for optimizing automatic memory management activities based on a specified level of latency further comprises:

computer usable program code for determining if an automatic memory management background thread is operating within specific parameters; and

computer usable program code, responsive to a determination that the automatic memory management background thread is not operating within specific parameters, for throttling acceptance of requests.

18. The computer program product of claim 17, wherein a request comprises a request to start a new communication session.

19. The computer program product of claim 13, wherein the computer usable program code for optimizing automatic memory management activities based on a specified level of latency further comprises:

computer usable program code for determining if an average automatic memory management activity time is above a specified threshold; and

computer usable program code, responsive to a determination that the average automatic memory management activity time is above a specified threshold, for throttling acceptance of requests.

20. A data processing system for reducing communication signaling protocol latency, the data processing system comprising:

a storage device, wherein the storage device stores computer usable program code; and

a processor, wherein the processor executes the computer usable program code to optimize automatic memory management activities based on a specified level of latency.
