Abstract

A method comprises predicting, based on corresponding historical workload data, a change in virtual network function demand during a future workload period, wherein the virtual network function is supported by a node. The method further comprises determining a target clock speed of one or more physical CPU cores of one or more processors of one or more servers in the node corresponding to the change in the virtual network function demand and adjusting the CPU CORE of the node to the target clock speed corresponding to the change in the virtual network function demand for the future workload period.

Claims (40)

1. A method, comprising:

predicting, based on historical workload data, a predicted change in virtual network function demand during a future workload period, wherein the virtual network function is supported by a node;

determining a target clock speed of a physical central processing unit (CPU) core in the node corresponding to the predicted change in the virtual network function demand;

adjusting the physical CPU core of the node to the target clock speed corresponding to the predicted change in the virtual network function demand for the future workload period, wherein adjusting the physical CPU core of the node is coordinated to a latency; and

calculating the latency, wherein the latency is based on:

an adjustment delay associated with changing a clock speed of the physical CPU core from an initial clock speed to the target clock speed, and

a network delay.

2. The method of claim 1 , further comprising:

collecting the historical workload data.

3. The method of claim 2 , wherein the historical workload data is based on a time period.

4. The method of claim 3 , wherein the time period is a date and time.

5. The method of claim 1 , further comprising:

comparing a recent virtual network function demand to the historical workload data to determine a difference between the recent virtual network function demand and the historical workload data,

wherein predicting the change in virtual network function demand is further based on the difference.

6. The method of claim 5 , wherein the comparison is based on a date or a time.

7. The method of claim 5 , wherein the comparison is based on a usage pattern.

8. The method of claim 5 , wherein the comparison identifies an anomalous event.

9. A computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:

predicting, based on historical workload data, a future demand during a future workload interval, wherein the future demand supports a virtual network function or container, and wherein the future demand is met by a server;

determining a target clock speed of at least one central processing unit (CPU) core corresponding to the future demand, wherein the at least one CPU core is within a processor in the server;

causing the at least one CPU core to adjust to the target clock speed corresponding to the future demand for the future workload interval; and

determining a target clock speed of at least one hyper-thread of a central processing unit (CPU) core corresponding to the future demand, wherein two or more hyper threads are supported by the at least one CPU core corresponding to the future demand.

10. The computer readable storage medium of claim 9 , the operations further comprising grouping cores or threads for common scaling.

11. A computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:

predicting, based on historical workload data, a predicted change in virtual network function demand during a future workload period, wherein the virtual network function is supported by a node;

determining a target clock speed of a physical central processing unit (CPU) core in the node corresponding to the predicted change in the virtual network function demand;

adjusting the physical CPU core of the node to the target clock speed corresponding to the predicted change in the virtual network function demand for the future workload period;

comparing a recent virtual network function demand to the historical workload data to determine a difference between the recent virtual network function demand and the historical workload data,

wherein predicting the change in virtual network function demand is further based on the difference, and

wherein the comparison identifies an anomalous event.

12. The computer readable storage medium of claim 11 , wherein adjusting the physical CPU core of the node is coordinated to a latency.

13. The computer readable storage medium of claim 12 , further comprising:

calculating the latency, wherein the latency is based on an adjustment delay associated with changing a clock speed of the physical CPU core from an initial clock speed to the target clock speed.

14. The computer readable storage medium of claim 13 , wherein the latency is based on a network delay.

15. The computer readable storage medium of claim 11 , further comprising:

collecting the historical workload data.

16. The computer readable storage medium of claim 15 , wherein the historical workload data is based on a time period.

17. The computer readable storage medium of claim 16 , wherein the time period is a date and time.

18. The computer readable storage medium of claim 11 , wherein the comparison is based on a date or a time.

19. The computer readable storage medium of claim 11 , wherein the comparison is based on a usage pattern.
