Christoph Hilz, Group SVP Core Network & Services of Deutsche Telekom, said, “Energy efficiency is a core design principle for our networks. This achievement shows how software-driven intelligence, cloud-native architecture, and hardware optimization combine to deliver measurable impact. Mavenir’s cloud-native core as part of DT’s Horizontal Telco Cloud Architecture were instrumental in enabling our full stack energy management approach. In collaboration with several partners including Mavenir, Telekom has developed a concept that reduces energy consumption across all layers of the network. We are rethinking the cloud architecture of the core network, creating a blueprint for the entire telecommunications industry.”
