ETSI Open Source Group TeraFlowSDN and the TeraFlow project, funded by the European Commission under Horizon 2020 Programme, have launched the second release of the TeraFlowSDN controller.
TeraFlowSDN Release 2 provides an innovative full-featured software-defined cloud-native SDN robust orchestrator and controller for transport networks. It provides novel SDN orchestration functionalities to the network with dedicated focus on security, scalability, and performance of network services. Moreover, novel network equipment will be supported as SDN controller.
“Our TeraFlowSDN second release provides unique features to the SDN community. Cloud-native SDN is the next evolution for transport networks and TeraFlowSDN is paving the way” (Ricard Vilalta, CTTC, ETSI TeraFlowSDN Chair)
TeraFlowSDN Release 2 provides extended and validated support for end-to-end transport network slicing over multiple network domains. TeraFlowSDN Release 2 includes complete SDN orchestration for L2/L3VPN provisioning, microwave networks, Point-to-Multipoint integration of XR optical transceivers, and interaction with optical SDN controllers through the Open Networking Foundation (ONF) Transport API (TAPI).
Moreover, SDN control is provided for OpenConfig-based routers and P4 whiteboxes. New features for P4 routers include loading a P4 pipeline on a given P4 switch; getting runtime information (i.e., flow tables) from the P4 switch; and pushing runtime entries into the P4 switch pipeline, thus allowing total usage of P4 switches.
Service Level Agreement (SLA) validation has been re-engineered through all the workflows, from Device monitoring to Service and Slice life cycle management. Thus, the Slice, Service, Policy, Device and Monitoring Components have been updated to support the necessary network automation workflows. Moreover, Slice grouping has also been introduced, along with the Path Computation Component. This component allows new use cases, such as energy-aware service placement.
Cybersecurity mechanisms have been updated, including novel components for attack detection (either distributed or centralized), attack inference, and attack mitigation. In addition, several novel use cases are supported. Distributed Ledger Technology (DLT) has also been extended to interact with the Inter-domain Component and use the deployed Hyperledger Fabric.
To validate the performance of the components developed and their potential contribution to end-users and early adopters of the TeraFlowSDN, three scenarios are being demonstrated: Autonomous Network Beyond 5G, Inter-domain and Cybersecurity. The source code is publicly available for download and installation.
TeraFlowSDN release 2.1 will take place on January 2023 and it will include new functionalities and provide bug fixing and additional features identified on the testing and validation activities.
