1. Introduction
The importance of energy efficiency in modern networks is
increasingly evident. In addition to reducing the power consumption
of devices, network technologies can be leveraged to redirect
traffic towards energy-efficient devices and paths, effectively
lowering the energy consumption of network communications.
[draft-cx-green-green-metrics] described various metrics can be used
to evaluate energy consumption.
[draft-liu-spring-sr-policy-energy-efficiency-00] describes how
energy-consumption information is utilized in SR networks. It
elaborates on the use of energy consumption information for path
computation in SR networks.
The metrics for energy consumption include:
Node Maximum Energy Consumption: The power consumption of a node at
full load, measured in watts.
Node Real-Time Energy Consumption: The real-time power consumption
of a node, measured in watts.
Node Maximum Unit Energy Consumption: The power consumption of a
node at full load divided by traffic, measured in watts per gigabyte
(W/GB).
Node Real-Time Unit Energy Consumption: The real-time power
consumption of a node divided by real-time traffic, measured in
watts per gigabyte (W/GB).
Node Average Unit Energy Consumption: The change in power
consumption of a node over a measurement period divided by the
change in traffic, measured in watts per gigabyte (W/GB).
Interface Maximum Unit Energy Consumption: The power consumption of
an interface at full load divided by traffic, measured in watts per
gigabyte (W/GB).
Interface Real-Time Unit Energy Consumption: The real-time power
consumption of an interface divided by real-time traffic, measured
in watts per gigabyte (W/GB).

Interface Average Unit Energy Consumption: The change in power

2.3. BGP-LS Board NLRI
For energy consumption information, devices can directly report it
to the controller via BGP-LS. Since the energy consumption data of a
device is typically collected on a per-board basis, this document
introduces a new BGP-LS NLRI type, BOARD NLRI, to report board-
related information.
[RFC7752] defines the NLRI format for BGP-LS.

4.6. IGP energy consumption Metric-Type for BGP-LS
Although the Metric-Type values advertised in IGP protocols do not need to be
completely consistent with those advertised in BGP-LS, we recommend maintaining
consistency with the values in IGP protocols when defining new values in BGP-LS. This
ensures easier mapping when adding new types in the future.
