Abstract

Certain exemplary embodiments comprise a method, comprising: in a BGP network comprising a plurality of neighbors: associating a desired COS policy for a specified interface with a BGP community value; and providing a BGP update message comprising the BGP community value.

Claims

1. A method, comprising:

in a BGP network comprising a plurality of neighbors;

associating a desired COS policy for a specified interface with a BGP community value; and

providing a BGP update message comprising the BGP community value.

2. The method of claim 1, further comprising:

determining the desired COS policy.

3. The method of claim 1, further comprising:

determining criteria for applying the desired COS policy.

4. The method of claim 1, further comprising:

determining the BGP community value.

5. The method of claim 1, further comprising:

generating the BGP update message.

6. The method of claim 1, wherein:

the BGP update message is provided to an Autonomous System management entity.

7. The method of claim 1, wherein:

the BGP community value comprises an address of the specified interface where the desired COS policy is to be applied.

8. A method, comprising:

in a BGP network comprising a plurality of neighbors;

receiving a BGP update message comprising a BGP community value associated with a desired COS policy and comprising an IP address that refers to an interface where the desired COS policy is to be applied; and

based on the received BGP update message, automatically changing from an operative COS policy to the desired COS policy on the interface.

9. The method of claim 8, further comprising:

based on the received BGP community value, determining the desired COS policy.

10. The method of claim 8, further comprising:

accessing the desired COS policy.

11. The method of claim 8, further comprising:

based on the received BGP community value, determining the IP address value of the interface.

12. The method of claim 8, further comprising:

accessing the interface.

13. The method of claim 8, further comprising:

implementing the desired COS policy on the interface.

14. The method of claim 8, wherein:

the BGP update message is received by an Autonomous System management entity.

15. The method of claim 8, wherein:

the BGP community value is not utilized to perform a specific routing decision.

16. The method of claim 8, wherein:

the BGP community value is an extended community value.

17. The method of claim 8, wherein:

the BGP community value is a standard community value.

18. The method of claim 8, wherein:

the desired COS policy comprises a plurality of rules governing use of network resources.

19. A machine readable medium storing instructions for activities comprising:

in a BGP network comprising a plurality of neighbors;

associating a desired COS policy for a specified interface with a BGP community value; and

providing a BGP update message comprising BGP the community value.

20. A machine readable medium storing instructions for activities comprising:

in a BGP network comprising a plurality of neighbors;

receiving a BGP update message comprising a BGP community value associated with a desired COS policy and comprising an IP address that refers to an interface where the desired COS policy is to be applied; and

based on the received BGP update message, automatically updating an operative COS policy to the desired COS policy on the interface.
