ETSI has published Standard ES 203 237, known as the Green Abstraction Layer (GAL), to enable flexible and scalable energy management for telecommunications networks. This architectural middleware provides a standardized interface that allows network devices to dynamically adapt power consumption based on real-time traffic profiles without requiring hardware upgrades. The GAL framework facilitates the discovery, provisioning, and monitoring of energy configurations, allowing operators to optimize the trade-off between network performance and energy costs. Developed by ETSI’s Environmental Engineering Technical Committee with support from the ECONET project, the standard is publicly available free of charge.
