ITU-T Recommendations

Supplement 52 to ITU-T L-series Recommendations proposes a set of good practices to improve the energy efficiency of cyber-physical applications – making use of Internet of things (IoT), artificial intelligence (AI), and digital twins. First, the Supplement introduces the cyber-physical paradigm, engineering reference framework, and a couple of system deployments models. Secondly, it defines three end-to-end use case typologies to be addressed (i.e., monitoring applications using smart IoT systems and AI software; smart applications using Edge computing and cloud data centre; and simulation applications using digital twin pattern). Energy efficiency practices are discussed adopting a circular value-chain model that consists of three main steps: data storage; data transfer/move; and data processing/analytics. Finally, this Supplement offers a set of recommended practices relating to each component of the three end-to-end use case typologies.
