What TeraFlowSDN is
TeraFlowSDN is an open-source, cloud-native software-defined networking controller for smart connectivity services and networks beyond 5G. Its microservices architecture supports end-to-end network orchestration and control. The project toolbox supports experiments in flow aggregation and management, equipment integration, AI- and ML-based security, and forensic evidence for multi-tenancy. Documented southbound drivers cover NetConf/OpenConfig, gNMI/OpenConfig, ONF Transport API, P4, IETF L2VPN and ACTN, optical interfaces, and microwave. Northbound connectors include the TFS API and interfaces for bandwidth management, L2VPN and L3VPN services, topology, and network slices. The API provides gRPC methods for managing contexts, topologies, devices, links, services, slices, connections, and policies. Release 7 highlights P4 device integration and optical-network automation, including telemetry, KPI management, analytics, and self-healing capabilities. TeraFlowSDN identifies Apache License 2.0 and can integrate with ETSI Open Source MANO and ETSI OpenSlice. Deployment documentation assumes Ubuntu Server and MicroK8s on a physical server or virtual machine with at least 4 cores, 8 GB RAM, 60 GB disk, and one NIC. The optical NetConf/OpenConfig driver is experimental and contains proprietary extensions.
Good
- Open source under Apache License 2.0.
- Supports a broad range of network interfaces.
- Integrates with ETSI Open Source MANO and OpenSlice.
- Includes a gRPC API for network resources.
Watch out
- Deployment documentation assumes Ubuntu Server and MicroK8s.
- Optical NetConf/OpenConfig driver is experimental.
- That driver contains proprietary extensions.
- Minimum documented requirements include 4 cores and 8 GB RAM.
Who it suits
TeraFlowSDN is aimed at telecommunications operators, vendors, research institutions, and research initiatives working on smart networks and services. It suits teams able to deploy and operate it on premises with the documented server and software requirements.
Verdict
TeraFlowSDN provides a broad controller and API surface for network orchestration, with optical automation and P4 features highlighted in Release 7. Deployment requires the stated infrastructure, and one optical driver remains experimental.
