Abstract

Aspects of a method and system for end-to-end management of energy efficient networking protocols are provided. In this regard, a path between two network nodes may be determined and one or more messages may be generated. The one or more messages may be communicated to one or more network nodes along the determined path and may configure an EEN control policy and/or one or more (EEN) parameters in those network nodes. The one or more generated messages may comprise a distinct marking that may, upon detection by the network nodes along the determined path, trigger configuration of the EEN control policy and/or EEN parameters within the one or more network nodes. The one or more messages may be may be utilized to enable and disable EEN in one or more network nodes along the path.

Claims

1. A method, comprising:

performing by one or more processors and/or circuits in a first network node;

determining a path between said first network node and a second network node;

generating a message for configuring one or more energy efficient networking (EEN) parameters within an intermediate network node along said determined path; and

communicating said generated message over said determined path to said intermediate network node, said generated message being used by said intermediate network node to configure an energy saving operation of said intermediate network node to accommodate an application running on one of said first network node and said second network node.

2. The method according to claim 1, wherein said generated message comprises a distinct marking that, upon detection by said intermediate network node along said determined path, triggers configuration of said one or more EEN parameters within said intermediate network node.

3. The method according to claim 1, wherein said message comprises:

fields defined by IEEE 802.1Qat; and

one or more fields that convey information for configuring EEN parameters along said determined path.

4. The method according to claim 1, comprising communicating said message utilizing simple network management protocol (SNMP).

5. The method according to claim 1, comprising communicating said message utilizing logical link discovery protocol (LLDP).

6. The method according to claim 1, comprising determining said path via communication of one or more packets along said determined path, wherein information identifying EEN capabilities of said intermediate network node along said determined path is inserted by said intermediate network node along said determined path as said one or more packets traverses said determined path.

7. The method according to claim 1, wherein said EEN parameters are stored in a physical layer device of said intermediate network node along said determined path.

8. The method according to claim 1, wherein said one or more EEN parameters are configured based on quality of service required for data to be communicated over said determined path.

9. The method according to claim 1, comprising configuring said one or more EEN parameters based on resource reservation packets communicated along said determined path.

10. A system, comprising:

one or more circuits for use in a network node, said one or more circuits being configured to;

determine a path between a first network node and a second network node;

generate a message for configuring one or more energy efficient networking (EEN) parameters within an intermediate network node along said determined network path; and

communicate said generated message over said determined path to said intermediate network node, said generated message being used by said intermediate network node to configure an operation that controls energy savings in said intermediate network node to accommodate an application running on one of said first network node and said second network node and/or information exchanged between said first network node and said second network node.

11. The system according to claim 10, wherein said generated message comprises a distinct marking that, upon detection by said intermediate network node along said determined path, triggers configuration of said one or more EEN parameters within said intermediate network node.

12. The system according to claim 10, wherein said message comprises:

fields defined by IEEE 802.1Qat; and

one or more fields that convey information for configuring EEN parameters along said determined path.

13. The system according to claim 10, wherein said one or more circuits are further configured to communicate said message utilizing simple network management protocol (SNMP).

14. The system according to claim 10, wherein said one or more circuits are further configured to communicate said message in accordance with logical link discovery protocol (LLDP).

15. The system according to claim 10, wherein said one or more circuits are further configured to determine said path via communication of one or more packets along said determined path, wherein information identifying EEN capabilities of said intermediate network node along said determined path is inserted by said intermediate network node along said determined path as said one or more packets traverses said determined path.

16. The system according to claim 10, wherein said EEN parameters are stored in a physical layer device of said intermediate network node along said determined path.

17. The system according to claim 10, wherein said one or more EEN parameters are configured based on quality of service required for data to be communicated over said determined path.

18. The system according to claim 10, wherein said one or more EEN parameters are configured based on resource reservation packets communicated along said determined path.

19. The system according to claim 10, wherein said EEN parameters control whether said energy saving operation of said intermediate network node is enabled or disabled.

20. A method, comprising:

performing by one or more processors and/or circuits in an intermediate network node in a path between a first network node and a second network node, said path being formed by a plurality of tired network links;

receiving a message for configuring one or more energy efficient networking parameters within said intermediate network node; and

configuring an energy saving operation of said intermediate network node based on said received message, wherein said configuration of said energy saving operation of said intermediate network node accommodates an application running on one of said first network node and said second network node and/or information exchanged between said first network node and said second network node.

21. The method according to claim 20, wherein said one or more energy efficient networking parameters are configured based on quality of service required for data to be communicated over said path.

22. The method according to claim 20, wherein said configuring comprises configuring whether an energy saving operation of said intermediate network node is enabled or disabled.

23. The method according to claim 20, wherein said first network node includes a media access controller and a physical layer transceiver.
