| Internet-Draft | Green BoF requirements collections | August 2024 |
| Stephan & Palmero | Expires 28 February 2025 | [Page] |
This memo extracts and groups requirements from the revisit of operator's requirements made in the last charter refinement work and from the drafts which provided material to the green BoF. The aim is to determine initial sets of requirements actionable at different levels of the framework.¶

This memo extracts and groups requirements from the revisit of operator's requirements made in the last charter refinement work [charter-refinement] and from the drafts which provided material [GREEN-BOF], [sustainability-insights], [legacy-path] and [rfc6988bis-green] to the green BoF. The aim is to determine initial sets of requirements actionable at different levels of the framework presented in [charter-refinement].¶
The tables below respect the format and the semantic of operators requirements table of [charter-refinement].¶
The table below is a copy of the operator'requirements table of [charter-refinement]. They are based on the inputs received from operators for the GREEN BoF [operators-inputs].¶
