This paper introduces a new Recommendation ITU-T Y.3021 “Framework of energy saving for Future Networks” [1], which was consented at the ITU-T SG13 meeting in October 2011. The paper first describes the need for energy saving of networks themselves, and reviews potential technologies. The paper then identifies major functions and their cyclic interactions, analyses possible impacts of introducing the technologies, and itemises the high level requirements for introducing the technologies.
