Sophia Antipolis, France, 18 November 2025
Building the Foundation for Autonomous 6G Transport Networks, ETSI is proud to announce the launch of TeraFlowSDN Release 6. With a large set of new features across automation, observability, optical integration, and security, this release establishes TeraFlowSDN as a programmable and intelligent SDN controller that bridges IP and optical domains with full lifecycle orchestration.
TeraFlowSDN Release 6 brings key advances, including policy-driven closed-loop automation, enhanced telemetry, IP–optical convergence, security and smoother integration with ETSI Open Source MANO (OSM), and ETSI OpenSlice (OSL).
The policy-based automation framework enables real-time network adaptation based on KPIs, while telemetry extensions like P4 in-band telemetry and OpenConfig/gNMI collectors improve monitoring and troubleshooting. The new IETF-aligned SIMAP connector, enables a new generation of Network Digital Twins, abstracting the underlying network topologies flavoured with structured real-time telemetry data.
The advances in IP–optical integration include support for flexgrid lightpaths, optical bandwidth expansion, management of coherent transceivers, and IPoWDM service management. Also, the Network Slice Controller was upgraded for closer alignment with IETF data models.
Additional security features such as a new programmable Firewall Agent for enabling end-to-end secured IP connectivity, and energy-aware network slice planning confirm TeraFlowSDN as a secure, programmable, and autonomous solution for managing 6G transport networks.
Upcoming Events
The SDG TFS#8 Plenary Meeting and Hackfest is taking place online from 18 November bringing an opportunity for new features in TFS Release 6 to be demonstrated and experimented by participants.
In addition, TeraFlowSDN Release 6 will be featured in the upcoming Joint SDG Ecosystem Day on 26 November, with 5 talks dedicated to TFS related research.
