The new ETSI specification defines the F5G end-to-end network architecture, incorporating SDN/NFV for control and Autonomous Network principles for management to support enhanced fixed broadband, full fibre connections, and guaranteed reliable experiences. Key design innovations include a data plane separation into Underlay and Service planes, a dual-fabric aggregation network combining IP/Ethernet and OTN, and seamless E2E full-stack slicing with traffic steering. The architecture utilizes EVPN as a unified, programmable Service Plane to balance performance and operational flexibility, allowing independent plane changes to meet diverse application needs. This foundation aims to enable sustainable, high-bandwidth communications essential for digital and green societal transitions.
