Liaison statement
LS on the creation of the Getting Ready for Energy-Efficient Networking Working Group in the IETF

1. Description

We are glad to inform you that a new Working Group (WG) Getting Ready for
Energy-Efficient Networking (GREEN), is created by the IETF. The WG held its
first meeting in November 2024, in Dublin, during IETF 121. The GREEN WG [1] 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. The GREEN WG is committed to focus initially on the following
deliverables:

- Informational documents that:
  - Define common terminology and metric definitions.
  - Categorize various types of metrics and measurements at component, device,
  and network levels.

- Definitions of YANG data models at the component level, device level, and
network level for energy-efficient network management, including energy usage
monitoring and energy consumption management.

- Informational documents that:
  - Define a set of architectural components for managing energy-efficient
  networks. - Describe incremental deployment considerations for new energy
  efficiency metrics, monitoring, capability discovery, and management within a
  network domain.

The GREEN WG would welcome the opportunity to collaborate with other standard
bodies on methods related to power management as they relate to networking
equipment and the network in general.

As with all IETF WGs, participation is open and most of the discussion happens
on the WG list [2] that can be subscribed to at [3].

More details on the WG, including active documents and future meetings, can be
found at [1].
