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 for networking, the 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 one or more messages for configuring one or more energy efficient networking (EEN) parameters within network nodes along said determined path; and

communicating said one or more generated messages over said determined path.

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

3. The method according to claim 1, wherein said one or more messages comprise:

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 one or more messages utilizing simple network management protocol (SNMP).

5. The method according to claim 1, comprising communicating said one or more messages 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 network nodes along said determined path is inserted by said network nodes 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 PHY of each of said network nodes along said determined path.

8. The method according to claim 1, wherein said one or more EEN parameters are configured based on applications running on said first network node and/or applications running on said second network node.

9. 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.

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

11. The method according to claim 1, comprising configuring one or more EEN parameters that enable and disable EEN.

12. A system for networking, the system comprising:

one or more processors and/or circuits for use in a network node, said one or more circuits being operable to;

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

generate one or more messages for configuring one or more energy efficient networking (EEN) parameters within each network node along said determined network path; and

communicating said one or more generated messages over said determined path.

13. The system according to claim 12, wherein said one or more generated messages comprise a distinct marking that, upon detection by said network nodes along said determined path, triggers configuration of said one or more EEN parameters within said one or more network nodes

14. The system according to claim 12, wherein said one or more messages comprise:

fields defined by IEEE 802.1Qat; and

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

15. The system according to claim 12, wherein said one or more circuits are operable to communicate said one or more messages utilizing simple network management protocol (SNMP).

16. The system according to claim 12, wherein said one or more processors and/or circuits are operable to communicate said one or more messages in accordance with logical link discovery protocol (LLDP).

17. The system according to claim 12, wherein said one or more processors and/or circuits are operable to determine said path via communication of one or more packets along said determined path, wherein information identifying EEN capabilities of said network nodes along said determined path is inserted by said network nodes along said determined path as said one or more packets traverses said determined path.

18. The system according to claim 12, wherein said EEN parameters are stored in a PHY of each of said network nodes along said determined path.

19. The system according to claim 12, wherein said one or more EEN parameters are configured based on applications running on said first network node and/or applications running on said second network node.

20. The system according to claim 12, wherein said one or more EEN parameters are configured based on quality of service required for data to be communicated over said determined path.

21. The system according to claim 12, wherein said one or more processors and/or circuits are operable to configure said one or more EEN parameters based on resource reservation packets communicated along said determined path.

22. The system according to claim 12, wherein said EEN parameters control whether EEN is enabled or disabled.
