Abstract

In particular embodiments, a method includes determining a data flow rate of the active connections at a proxy, comparing the data flow rate to a first pre-determined threshold value, and, when the data flow rate exceeds the first pre-determined threshold value, creating one or more new processing threads associated with the proxy.

Claims

1. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

determine a data flow rate of the active connections at a proxy;

compare the data flow rate to a first pre-determined threshold value; and

when the data flow rate exceeds the first pre-determined threshold value, create one or more new processing threads associated with the proxy.

2. The system of claim 1, the processors being further operable when executing the instructions to:

when the data flow rate is less than or equal to a second pre-determined threshold value, kill one or more existing processing threads associated with the proxy.

3. The system of claim 1, wherein determining a data flow rate of the active connections at the proxy comprises analyzing one or more socket buffers associated with the proxy.

4. The system of claim 3, wherein analyzing one or more socket buffers associated with the proxy comprises determining a number of bytes written to the socket buffers in a pre-determined period of time.

5. The system of claim 1, wherein a number of new processing threads created by the proxy is based at least in part on a load of a machine on which the proxy resides.

6. The system of claim 5, wherein a network gateway resides on the machine.

7. The system of claim 2, wherein the second pre-determined threshold value is equal to the first pre-determined threshold value.

8. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

determine a data flow rate of the active connections at a proxy;

compare the data flow rate to a first pre-determined threshold value; and

when the data flow rate exceeds the first pre-determined threshold value, create one or more new processing threads associated with the proxy.

9. The media of claim 8, the software being further operable when executed to:

when the data flow rate is less than or equal to a second pre-determined threshold value, kill one or more existing processing threads associated with the proxy.

10. The media of claim 8, wherein determining a data flow rate of the active connections at the proxy comprises analyzing one or more socket buffers associated with the proxy.

11. The media of claim 10, wherein analyzing one or more socket buffers associated with the proxy comprises determining a number of bytes written to the socket buffers in a pre-determined period of time.

12. The media of claim 8, wherein a number of new processing threads created by the proxy is based at least in part on a load of a machine on which the proxy resides.

13. The media of claim 12, wherein a network gateway resides on the machine.

14. A method comprising:

determining a data flow rate of the active connections at a proxy;

comparing the data flow rate to a first pre-determined threshold value; and

when the data flow rate exceeds the first pre-determined threshold value, creating one or more new processing threads associated with the proxy.

15. The method of claim 14, further comprising:

when the data flow rate is less than or equal to a second pre-determined threshold value, killing one or more existing processing threads associated with the proxy.

16. The method of claim 14, wherein determining a data flow rate of the active connections at the proxy comprises analyzing one or more socket buffers associated with the proxy.

17. The method of claim 16, wherein analyzing one or more socket buffers associated with the proxy comprises determining a number of bytes written to the socket buffers in a pre-determined period of time.

18. The method of claim 14, wherein a number of new processing threads created by the proxy is based at least in part on a load of a machine on which the proxy resides.

19. The method of claim 18, wherein a network gateway resides on the machine.

20. The method of claim 15, wherein the second pre-determined threshold value is equal to the first pre-determined threshold value.
