Abstract: Devices, systems, methods, and processes for feature level power calibration are described herein. Network devices include sensors that generate sensor readings indicative of various device parameters. A calibration logic utilizes the sensor readings and feature permutations associated with the sensor readings to predict a feature level power consumption for all features of the network device. The calibration logic then applies a calibration factor to the predicted feature level power consumption and obtains an actual feature level power consumption. Using the actual feature level power consumption, the calibration logic determines an actual power consumption for feature licenses of the network device. The feature and feature license level power consumption is utilized for determining which features or feature licenses can be deactivated when the device power consumption is outside a threshold limit. Such dynamic deactivation ensures that the network device accurately meets the sustainability goals.
