Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. A power management component in a system may be configured to obtain measurements associated with a signal path used for communication by the system via a communication port, and manage power use in the system based on the obtained measurement. Managing the power use may include determining, based on the obtained measurements, connectivity related information associated with connectivity of the system via the communication port, and applying based on the information one or more power use reduction measures, with the one or more power use reduction measures including at least transitioning between different power related states.

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.

The Distributed Software Defined Network (dSDN) disclosed herein is an end-to-end architecture that enables secure and flexible programmability across a network with full lifecycle management of services and infrastructure applications (fxDeviceApp). The dSDN also harmonizes application deployment across the network independent of the hardware vendor. As a result, the dSDN simplifies the network deployment lifecycle from concept to design to implementation to decommissioning.

Techniques for managing energy use of a computing deployment are provided. In one embodiment, a computer system can establish a performance model for one or more components of the computing deployment, where the performance model models a relationship between one or more tunable parameters of the one or more components and an end-to-end performance metric, and where the end-to-end performance metric reflects user-observable performance of a service provided by the computing deployment. The computer system can further execute an algorithm to determine values for the one or more tunable parameters that minimize power consumption of the one or more components, where the algorithm guarantees that the determined values will not cause the end-to-end performance metric, as calculated by the performance model, to cross a predefined threshold. The computer system can then enforce the determined values by applying changes to the one or more components.
