Abstract

A device may identify a plurality of first values associated with network traffic of a label-switched path of a plurality of label-switched paths. The device may determine an adjustment policy based on the plurality of first values. The adjustment policy may include one or more factors associated with a plurality of second values. The plurality of second values may be determined based on the plurality of first values. The device may implement the adjustment policy in association with the label-switched path. A bandwidth reservation of the label-switched path may be adjusted based on the adjustment policy. The adjustment policy may be implemented for fewer than all of the plurality of label-switched paths.

First claim

What is claimed is:

1. A method comprising:
receiving, by one or more devices, information that identifies a label-switched path;
determining, by the one or more devices, multiple policies for the label-switched path;
identifying, by the one or more devices, a month; and
implementing, by the one or more devices and based on the month, a particular policy, of the multiple policies, in association with the label-switched path,
the particular policy enabling adjustment of a bandwidth reservation of the label-switched path.

2. The method of claim 1 , wherein the label-switched path carries virtual private network (VPN) traffic, and
wherein the label-switched path exhibits different traffic behavior based on a day of week.

3. The method of claim 1 , wherein the label-switched path carries streaming media traffic, and
wherein the label-switched path exhibits different traffic behavior based on a time of day.

4. The method of claim 1 , wherein implementing the particular policy comprises:
providing, to an ingress routing device, information that causes the ingress routing device to implement the particular policy.

5. The method of claim 1 , wherein implementing the particular policy comprises:
adjusting attributes of the label-switched path based on the particular policy.

6. The method of claim 1 , wherein the information that identifies the label-switched path is received from an ingress routing device, and
wherein the information that identifies the label-switched path is information that identifies network traffic behavior associated with the label-switched path.

7. The method of claim 1 , further comprising:
determining an updated policy based on implementing the particular policy.

8. A system, comprising:
one or more memories; and
one or more processors configured to:
receive information that identifies a label-switched path;
determine multiple policies for the label-switched path;
identify a month; and
implement, based on the month, a particular policy, of the multiple policies, in association with the label-switched path,
the particular policy enabling adjustment of a bandwidth reservation of the label-switched path.

9. The system of claim 8 , wherein the label-switched path carries virtual private network (VPN) traffic, and
wherein the label-switched path exhibits different traffic behavior based on a day of week.

10. The system of claim 8 , wherein the label-switched path carries streaming media traffic, and
wherein the label-switched path exhibits different traffic behavior based on a time of day.

11. The system of claim 8 , wherein the one or more processors, when implementing the particular policy, are configured to:
provide, to an ingress routing device, information that causes the ingress routing device to implement the particular policy.

12. The system of claim 8 , wherein the one or more processors, when implementing the particular policy, are configured to:
adjust attributes of the label-switched path based on the particular policy.

13. The system of claim 8 , wherein the information that identifies the label-switched path is received from an ingress routing device, and
wherein the information that identifies the label-switched path is information that identifies network traffic behavior associated with the label-switched path.

14. The system of claim 8 , wherein the one or more processors are further configured to:
determine an updated policy based statistics associated with the particular policy.

15. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by one or more processors, cause the one or more processors to:
receive information that identifies a label-switched path;
determine multiple policies for the label-switched path;
identify a month; and
implement, based on the month, a particular policy, of the multiple policies, in association with the label-switched path,
the particular policy enabling adjustment of a bandwidth reservation of the label-switched path.

16. The non-transitory computer-readable medium of claim 15 , wherein the label-switched path carries virtual private network (VPN) traffic, and
wherein the label-switched path exhibits different traffic behavior based on a day of week.

17. The non-transitory computer-readable medium of claim 15 , wherein the label-switched path carries streaming media traffic, and
wherein the label-switched path exhibits different traffic behavior based on a time of day.

18. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the one or more processors to implement the particular policy, cause the one or more processors to:
provide, to an ingress routing device, information that causes the ingress routing device to implement the particular policy.

19. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the one or more processors to implement the particular policy, cause the one or more processors to:
adjust attributes of the label-switched path based on the particular policy.

20. The non-transitory computer-readable medium of claim 15 ,
wherein the month is a time frame, and
wherein the label-switched path includes network traffic behavior models that differ based on the time frame.
