Green has become a global topic. The United Nations and the vast majority of governments agree that climate change and the need to curb greenhouse gas emissions are the major challenges of our time. Therefore, improving energy efficiency and reducing electricity consumption are becoming increasingly important for society and many industries. The networking industry is no exception. The IETF conducted a study on the energy costs of the IETF meeting three times a year. The results showed that it was found that 99% of energy consumption came from air travel.¶
Recently, the GREEN WG was formed. It is chartered to explore use cases, derive requirements, and provide solutions for identifying and characterizing energy efficiency metrics, methods related to energy consumption of network devices, and optimizing energy efficiency across the network. network. In addition, there are several papers that discuss green networks, and some work [I-D.cx-green-ps] summarizes the energy-saving possibilities that exist in the network.and [I-D.wang-cats-green-challenges] summarizes a number of challenges faced by cats considering green. It has become a hot topic to carry out research on web technologies that consider green.¶
This document describes a framework for Getting Ready for Energy-Efficient Networking(GREEN).¶
Figure 1 shows a framework of reference for GREEN that addresses the basic requirements raised during the BOF discussion[I-D.stephan-green-bof-reqs-collections]. Energy Efficiency Management Function is implemented inside the device or in a controller.¶

Geared towards Getting Ready for Energy-Efficient Networking, the green metrics include the energy consumption of network devices and so on. The following describes how green metrics are distributed under both distributed and centralized models.¶
Figure 2 shows an example of green metric dessimination based on distributed model. In this example, the green metrics of the device can be distributed in a distributed manner. One of the G-A reports the aggregated green indicators to the Energy-Efficiency Management function component.¶

In Figure 3, green metrics can be distributed in a centralized way. In this example, the device's green metrics can be reported from G-A to the Energy-Efficiency Management function component in a centralized manner.¶
