Abstract

A system for throttling data traffic on a network to a client includes an application node and a throttle manager. The application node receives requests from the client via the network. The throttle manager is in communication with the application node. The throttle manager is configured to track a parameter that is based on a number of active requests associated with a user identifier associated with the client. The throttle manager is configured to determine whether to restrict responses to the requests responsive to a relationship of the parameter to a threshold.

Claims

1. A method of throttling data traffic to a client comprising:

receiving notification of a client request associated with a user identifier;

incrementing a recorded number of active requests for the user identifier;

determining, responsive to the incremented number of active requests, whether a parameter based on the incremented recorded number of active requests is above a threshold; and

determining whether to restrict data traffic to the client responsive to a relationship of the parameter to the threshold.

2. The method of claim 1, further comprising sending a message to direct that the user identifier be added to a list of user identifiers to be throttled responsive to the parameter being above the threshold.

3. The method of claim 1, further comprising determining whether the user identifier is on a list of user identifiers to be throttled in response to the parameter being below the threshold.

4. The method of claim 3, further comprising sending a message to remove the user identifier from the list in response to the user identifier being on the list.

5. The method of claim 3, further comprising receiving an indication that a response is being sent to the client in response to the user identifier not being on the list.

6. The method of claim 5, further comprising decrementing the recorded number of active requests in response to receipt of the indication.

7. The method of claim 1, wherein the parameter is at least one of a number of active requests and a number of active requests per a given unit of time.

8. The method of claim 8, further comprising decrementing the recorded number of active requests in response to receipt of a message indicating that data traffic to the client has been restricted.

9. A computer program product for throttling data traffic to a client, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion capable of receiving notification of a client request from a user identifier;

a second executable portion capable of incrementing a recorded number of active requests for the user identifier;

a third executable portion capable of determining, responsive to the incremented number of active requests, whether a parameter based on the incremented recorded number of active requests is above a threshold; and

a fourth executable portion capable of determining whether to restrict data traffic to the client responsive to a relationship of the parameter to the threshold.

10. The computer program product of claim 9, further comprising a fifth executable portion capable of sending a message to direct the user identifier to be added to a list of user identifiers to be throttled responsive to the parameter being above the threshold.

11. The computer program product of claim 9, further comprising a fifth executable portion capable of determining whether the user identifier is on a list of user identifiers to be throttled in response to the parameter being below the threshold.

12. The computer program product of claim 11, further comprising a sixth executable portion capable of sending a message to remove the user identifier from the list in response to the user identifier being on the list.

13. The computer program product of claim 11, further comprising a sixth executable portion capable of receiving an indication that a response is being sent to the client in response to the user identifier not being on the list.

14. The computer program product of claim 13, further comprising a seventh executable portion capable of decrementing the recorded number of active requests in response to receipt of the indication.

15. The computer program product of claim 9, wherein the parameter is at least one of a number of active requests and a number of active requests per a given unit of time.

16. A system for throttling data traffic on a network to a client, the system comprising:

an application node receiving requests from the client via the network; and

a throttle manager in communication with the application node, the throttle manager being configured to track a parameter that is based on a number of active requests associated with a user identifier associated with the client,

wherein the throttle manager is configured to determine whether to restrict responses to the requests responsive to a relationship of the parameter to a threshold.

17. The system of claim 16, wherein the throttle manager is configured to direct the application node to add the user identifier to a list of user identifiers to be throttled responsive to the parameter being above the threshold.

18. The system of claim 17, wherein the application node is configured to send an error message to the client in response to the user identifier being on the list.

19. The system of claim 16, wherein the throttle manager is configured to determine whether the user identifier is on a list of user identifiers to be throttled in response to the parameter being below the threshold.

20. The system of claim 19, wherein the throttle manager is configured to send a message to the application node directing the application node to remove the user identifier from the list in response to the user identifier being on the list.

21. The system of claim 19, wherein the application node is configured to send an indication to the throttle manager indicating that a response is being sent to the client in response to the user identifier not being on the list.

22. The system of claim 21, wherein the throttle manager is configured to decrement the recorded number of active requests in response to the indication from the application node.

23. The system of claim 16, wherein the parameter is at least one of a number of active requests and a number of active requests per a given unit of time.

24. A method of throttling data traffic to a client comprising:

receiving a client request associated with a user identifier;

relaying the client request to a throttle manager configured to track a parameter that is based on a number of active requests received from the user identifier;

adding the user identifier to a list of user identifiers to be throttled in response to a first message from the throttle manager;

removing the user identifier from the list in response to a second message from the throttle manager;

providing indication to the throttle manager that a response is sent to the client in response to the user identifier not being on the list; and

restricting data traffic to the client in response to the user identifier being on the list.

25. The method of claim 24, further comprising sending an error message to the client in response to the user identifier being on the list.

26. A computer program product for throttling data traffic to a client, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion capable of receiving a client request associated with a user identifier;

a second executable portion capable of relaying the client request to a throttle manager configured to track a parameter that is based on a number of active requests received from the user identifier;

a third executable portion capable of adding the user identifier to a list of user identifiers to be throttled in response to a first message from the throttle manager;

a fourth executable portion capable of removing the user identifier from the list in response to a second message from the throttle manager;

a fifth executable portion capable of providing indication to the throttle manager that a response is sent to the client in response to the user identifier not being on the list; and
