The 6G-NETFAB project aims to transform the optical fiber communication network into an integrated 6G network structure, known as the Network Fabric, through the use of innovative, distributed switching nodes. The focus lies on separating software from hardware and developing open interfaces. New control algorithms and the development of switches in hardware, software, and signal processing are planned to enable flexible networks with variable data streams.
Funded by the Federal Ministry of Education and Research
Duration: October 2022 – September 2025
The project aims to develop a pioneering, open, and disaggregated 6G Network Fabric as the backbone for future 6G networks. This comprehensive network architecture is based on Disaggregated Open Transport Switches (DOTS), which combine modular white-box hardware with cloud-native, open software interfaces. The primary goal is to create flexible, energy-efficient, and reliable control for 6G transport networks.
The 6G Network Fabric offers:
- Flexibility: Configurable network components spanning the entire 6G network, from fronthaul to core.
- Dynamism: Scalable solutions to meet growing capacity demands and technological advancements.
- Innovation: Accelerated market entry for new technologies through open hardware and software development.
Key innovations include energy-efficient high-performance transmission modules, SDN-based control, and centralized management for the distributed network structure. The developed system demonstrator will serve as the foundation for European high-performance 6G products while fostering technological sovereignty, sustainability, and education in the 6G domain.
