Abstract

A method and system of an embodiment may include identifying a power source used by a network element, determining a carbon footprint of a unit of power usage from the power source, identifying one or more components associated with the network element used for a network operation performed by the network element, determining the power usage of the one or more identified components during the process, and calculating the carbon footprint of the process performed by the network element.

Claims

1. A method, comprising:

identifying one or more components associated with a first network element used for a network operation performed by the first network element; and

determining power usage of the one or more identified components during the network operation;

determining, using at least one computer processor, a first carbon footprint for the network operation;

comparing the first carbon footprint with a second carbon footprint of a network operation performed by a second network element; and

selecting one of the first network element and the second network element based at least in part on a carbon footprint size.

2. The method of claim 1, wherein determining a first carbon footprint comprises:

identifying a power source used by the first network element;

determining a carbon footprint of a unit of power usage from the power source; and

calculating the first carbon footprint of the network operation performed by the first network element.

3. The method of claim 1, wherein the network operation comprises a step utilized to handle a packet.

4. The method of claim 1, wherein the network operation comprises a step utilized to perform a network service.

5. The method of claim 4, wherein the network service comprises at least one of:

a transmission control protocol connection, a user datagram protocol connectionless interaction, a hypertext transfer protocol connection, a user datagram protocol streaming operation, a file transfer, a video on demand download, a plain old telephone system (POTS) call, a voice over Internet protocol (VOIP) call, a cellular call, an instant message, an IPTV program, a HDTV program broadcast, a web service interaction, and a web search engine interaction.

6. The method of claim 1, wherein the first network element comprises at least one of:

transmission links, switches, routers, servers, databases, network interface cards, link amplifiers, link regenerators, radio transmitters, cellular radios, software-defined radios, switches, routers, gateways, and softswitches.

7. The method of claim 2, further comprising storing the calculated carbon footprint.

8. The method of claim 7, wherein the calculated carbon footprint is stored in a management information base associated with the network element.

9. The method of claim 2, further comprising basing a routing decision at least in part on the carbon footprint.

10. The method of claim 9, wherein a generalized multiprotocol label switching network bases one or more routing decisions at least in part on the carbon footprint.
