Sophia Antipolis, France, 11 May 2026
ETSI is pleased to announce the launch of TeraFlowSDN Release 7. With a broad range of new features spanning P4-device integration, sophisticated automation for multi-granular optical networks, and expanded Northbound Interface (NBI) capabilities, this release positions TeraFlowSDN as the most advanced open-source Network Automation Framework.
TeraFlowSDN Release 7 brings key advances, including:
- Advanced P4 Programmability and 5G UPF Support: This release significantly deepens the controller’s integration with P4-programmable hardware, most notably through a new service handler designed for 5G User Plane Function (UPF) offloading providing developers with the granular control necessary for high-performance edge processing and hardware-accelerated networking.
- Next-Generation Optical Networking and Automation: TeraFlowSDN continues to lead in optical orchestration by implementing a robust closed-loop automation framework tailored for multi-granular nodes. This update integrates telemetry, KPI management, and analytics to enable self-healing capabilities, while new Northbound Interfaces (NBIs) for Optical Slices and Media Channel Services allow for the automated, flexible provisioning of high-capacity optical links.
- Standardised Interoperability and NBI Extensions: To ensure seamless adoption within carrier ecosystems, the release features extensive alignment with industry standards, including IETF NETWORK NBI extensions for IS-IS Traffic Engineering and updated YANG models. Furthermore, the integration of gNMI/OpenConfig SBI drivers for L2VPNs – validated through end-to-end testing with ETSI OSM -ensures that TeraFlowSDN remains a highly interoperable solution for multi-vendor, multi-layer environments.
- Enhanced DevOps and Ecosystem Reliability: The latest update prioritises carrier-grade stability with a comprehensive overhaul of the CI/CD pipeline and the introduction of the IETF SIMAP AI-Engine Framework.
Upcoming Events
The SDG TFS#9 Plenary Meeting will take place online on 21 May 2026, bringing an opportunity for new features in TFS Release 7 to be presented.
