Abstract

A virtual provider edge server may include different modules that implement a hybrid provider edge. A flow detection module may sample received traffic through a server and adaptively detect flows to be offloaded. An offloading module may be an SDN controller that controls the flow tables of a switch that data traffic is offloaded to.

First claim

What is claimed:

1. An apparatus comprising:
a processor; and
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
receiving data from a switch during a period;
sampling the data during the period;
determining a plurality of characteristics associated with the sampled data;
based on a first characteristic of the plurality of characteristics reaching a threshold, determining criteria to indicate data to offload through the switch; and
based on the determining the criteria to indicate data to offload through the switch, adjusting a data path of the indicated data to bypass the apparatus for subsequent data received at the switch and matching the criteria.

2. The apparatus of claim 1 , wherein the first characteristic comprises a number of times data with a first internet protocol address has been sampled during the period.

3. The apparatus of claim 1 , wherein the criteria comprises an internet protocol address range.

4. The apparatus of claim 1 , wherein the first characteristic comprises a number of times data with a first port number has been sampled during the period.

5. The apparatus of claim 1 , wherein the criteria comprises a time duration to adjust the data path.

6. The apparatus of claim 1 , the operations further comprising periodically sending a request for a statistic associated with a data flow through the switch.

7. The apparatus of claim 1 , the operations further comprising periodically sending a request for a statistic, wherein the statistic comprises a rate of data with a first internet protocol address over a second period.

8. A method comprising:
receiving, by a virtual machine, data from a switch during a period;
sampling the data during the period;
determining a plurality of characteristics associated with the sampled data;
based on a first characteristic of the plurality of characteristics reaching a threshold, determining criteria to indicate data to offload through the switch; and
based on the determining the criteria to indicate data to offload through the switch, adjusting a data path of the indicated data to bypass the virtual machine for subsequent data received at the switch and matching the criteria.

9. The method of claim 8 , wherein the first characteristic comprises a number of times data with a first internet protocol address has been sampled during the period.

10. The method of claim 8 , wherein the criteria comprises an internet protocol address range.

11. The method of claim 8 , wherein the first characteristic comprises a number of times data with a first port number has been sampled during the period.

12. The method of claim 8 , wherein the criteria comprises a time duration to adjust the data path.

13. The method of claim 8 , further comprising periodically sending a request for a statistic associated with a data flow through the switch.

14. The method of claim 8 , further comprising periodically sending a request for a statistic, wherein the statistic comprises a rate of data with a first internet protocol address over a second period.

15. A computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
receiving, by a virtual machine, data from a switch during a period;
sampling the data during the period;
determining a plurality of characteristics associated with the sampled data;
based on a first characteristic of the plurality of characteristics reaching a threshold, determining criteria to indicate data to offload through the switch; and
based on the determining the criteria to indicate data to offload through the switch, adjusting a data path of the indicated data to bypass the virtual machine for subsequent data received at the switch and matching the criteria.

16. The computer readable storage medium of claim 15 , wherein the first characteristic comprises a number of times data with a first internet protocol address has been sampled during the period.

17. The computer readable storage medium of claim 15 , wherein the criteria comprises an internet protocol address range.

18. The computer readable storage medium of claim 15 , wherein the first characteristic comprises a number of times data with a first port number has been sampled during the period.

19. The computer readable storage medium of claim 15 , wherein the criteria comprises a time duration to adjust the data path.

20. The computer readable storage medium of claim 15 , the operations further comprising periodically sending a request for a statistic, wherein the statistic comprises a rate of data with a first internet protocol address over a second period.
