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 device, comprising:
a memory; and
one or more processors to:
receive information that identifies network traffic behavior associated with a label-switched path of a plurality of label-switched paths,
the network traffic behavior being associated with a plurality of first values associated with network traffic of the label-switched path;
determine an automatic bandwidth adjustment policy based on the network traffic behavior,
the automatic bandwidth adjustment policy including multiple factors,
the multiple factors being associated with a plurality of second values, and
the plurality of second values being determined based on the plurality of first values;
implement the automatic bandwidth adjustment policy in association with the label-switched path,
implementing the automatic bandwidth adjustment policy causing a bandwidth reservation of the label-switched path to be adjusted based on the automatic bandwidth adjustment policy;
determine a quantity of bandwidth reservation adjustments that were made based on implementing the automatic bandwidth adjustment policy; and
determine an updated automatic bandwidth adjustment policy based on the quantity of bandwidth reservation adjustments.

2. The device of claim 1 , where the one or more processors are further to:
determine another automatic bandwidth adjustment policy based on the network traffic behavior associated with the label-switched path; and
where the one or more processors, when implementing the automatic bandwidth adjustment policy, are to:
implement the automatic bandwidth adjustment policy in association with a first time frame and implement the other automatic bandwidth adjustment policy in association with a second time frame,
the second time frame being different than the first time frame.

3. The device of claim 1 , where the one or more processors are further to:
provide, to another device, information that identifies the automatic bandwidth adjustment policy,
the other device adjusting the bandwidth reservation of the label-switched path based on the automatic bandwidth adjustment policy; and

where the one or more processors, when implementing the automatic bandwidth adjustment policy, are to:
implement the automatic bandwidth adjustment policy based on providing the information that identifies the automatic bandwidth adjustment policy.

4. The device of claim 1 , where the automatic bandwidth adjustment policy includes at least one of:
a sample interval value,
an adjustment interval value,
an adjustment threshold value,
an overflow threshold value, or
an underflow threshold value.

5. The device of claim 1 , where the one or more processors are further to:
receive information that identifies bandwidth usage values associated with the label-switched path; and
provide information that causes a bandwidth reservation value of the label-switched path to be adjusted based on the bandwidth usage values and the automatic bandwidth adjustment policy.

6. The device of claim 1 , where the one or more processors are further to:
determine another automatic bandwidth adjustment policy for another label-switched path of the plurality of label-switched paths,
the other automatic bandwidth adjustment policy being different than the automatic bandwidth adjustment policy; and

implement the other automatic bandwidth adjustment policy in association with the other label-switched path.

7. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by one or more processors of a first device, cause the one or more processors to:
receive, from a second device, a plurality of bandwidth usage values associated with a plurality of label-switched paths;
determine an automatic bandwidth adjustment policy based on the plurality of bandwidth usage values,
the automatic bandwidth adjustment policy including multiple factors,
the multiple factors being associated with a plurality of second values, and
the plurality of second values being determined based on the plurality of bandwidth usage values;

provide, to the second device, information that identifies the automatic bandwidth adjustment policy and that causes the second device to adjust a bandwidth reservation of a label-switched path, of the plurality of label-switched paths, based on the automatic bandwidth adjustment policy;
determine a quantity of bandwidth reservation adjustments that were made based the automatic bandwidth adjustment policy; and

determine an updated automatic bandwidth adjustment policy based on the quantity of bandwidth reservation adjustments.

8. The non-transitory computer-readable medium of claim 7 ,
where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
determine a variation between a minimum bandwidth usage value and a maximum bandwidth usage value associated with the label-switched path for a particular time frame,
the plurality of bandwidth usage values including the minimum bandwidth usage value and the maximum bandwidth usage value; and
determine an overflow threshold value based on the variation; and
where the one or more instructions, that cause the one or more processors to determine the automatic bandwidth adjustment policy, cause the one or more processors to:

determine the automatic bandwidth adjustment policy based on the overflow threshold value.

9. The non-transitory computer-readable medium of claim 7 , where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
provide information that causes the second device to implement another automatic bandwidth adjustment policy in association with another label-switched path, of the plurality of label-switched paths,
the other automatic bandwidth adjustment policy being different than the automatic bandwidth adjustment policy.

10. The non-transitory computer-readable medium of claim 7 , where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
determine another automatic bandwidth adjustment policy based on the plurality of bandwidth usage values; and
where the one or more instructions, that cause the one or more processors to provide the information that identifies the automatic bandwidth adjustment policy, cause the one or more processors to:
provide the information that identifies the automatic bandwidth adjustment policy and the other automatic bandwidth adjustment policy to cause the second device to implement the automatic bandwidth adjustment policy at a first time and to implement the automatic bandwidth adjustment policy at a second time that is different than the first time.

11. The non-transitory computer-readable medium of claim 7 ,
where the one or more instructions, when executed by the one or more processors, further cause the one or more processors to:
determine an amount of time where one or more bandwidth usage values, of the plurality of bandwidth usage values, are within a threshold range; and
determine an adjustment interval value based on the amount of time; and
where the one or more instructions, that cause the one or more processors to determine the automatic bandwidth adjustment policy, cause the one or more processors to:

determine the automatic bandwidth adjustment policy based on the adjustment interval value.

12. The non-transitory computer-readable medium of claim 7 , where the one or more instructions, when executed by the one or more processors, further cause the one
