Huawei Telefonica For.Eco Cisco Systems, Inc. Orange Huawei Recognizing the urgent need for energy efficiency, this document specifies a management framework focused on devices and device components within, or connected to, interconnected systems. The framework aims to optimize energy usage and ensure interoperability across diverse systems. Leveraging data from existing use cases, it delivers actionable metrics to support effective energy management and informed decision-making. Furthermore, the framework proposes mechanisms for representing and organizing timestamped telemetry data using YANG models and metadata, enabling transparent and reliable monitoring. This structured approach facilitates improved energy efficiency through consistent energy management practices.
