  • Patent number: 11818006
    Abstract: Techniques are provided for improving the environmental sustainability of a networking device and/or a networking system. In one example, a sustainability server obtains power consumption data of a networking device on a per-plane basis. Based on the power consumption data, the sustainability server computes an individual sustainability score that indicates a level of environmental sustainability of the networking device. The sustainability server further analyzes the power consumption data on the per-plane basis. In response to analyzing the power consumption data on the per-plane basis, the sustainability server provides a recommendation to implement a change to a configuration or operating parameter of the networking device, or to a networking system that includes the networking device, to improve the individual sustainability score.
