The record

Purpose: TeraFlowSDN is an open-source, cloud-native SDN controller for smart connectivity services and networks beyond 5G.
Architecture: It uses a cloud-native microservices architecture for end-to-end network orchestration and control.
Use cases: The project describes its toolbox as supporting experiments in flow aggregation and management, network equipment integration, AI and ML-based security, and forensic evidence for multi-tenancy.
License: The project site identifies Apache License 2.0 for TeraFlowSDN.
Integrations: The project says TeraFlowSDN can integrate with ETSI Open Source MANO and ETSI OpenSlice.
Release 7: Release 7 highlights P4 device integration, automation for multi-granular optical networks, and expanded northbound interface capabilities.
Optical automation: Release 7 describes telemetry, KPI management, analytics, and self-healing capabilities for optical networks, plus interfaces for optical slices and media channel services.
Network interfaces: Documented southbound drivers include NetConf/OpenConfig, gNMI/OpenConfig, ONF Transport API, P4, IETF L2VPN and ACTN, optical interfaces, and microwave.
Northbound interfaces: Documented northbound connectors include the TFS API, ETSI bandwidth management, IETF L2VPN and L3VPN service delivery, network topology, and network slice service.
API: The TFS API exposes gRPC methods for managing contexts, topologies, devices, links, services, slices, connections, and policies.
Security: The site describes AI and ML-based security and forensic evidence for multi-tenancy as areas the project toolbox supports experimentation in.
Support: The project provides a documentation wiki and directs users who have setup issues to contact the team through Slack.
Deployment requirements: The documentation assumes a physical server or virtual machine with at least 4 cores, 8 GB RAM, 60 GB disk, and one NIC, running Ubuntu Server and MicroK8s.
Documented limitation: The documentation marks the NetConf/OpenConfig Optical driver as experimental and warns that it contains proprietary extensions.
