Demo Paper: "Slice Grouping for Transport Network Slices Using Hierarchical Multi-domain SDN Controllers"
2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
This demonstration showcases how TeraFlowSDN provides support for hierarchical control of multiple heterogeneous SDN domains (through IP, microwave and optical technologies). Different transport slices are offered with multiple SLAs and grouped to optimize resources.
Conferences
End-to-End Inter-domain Transport Network Slice Management Using DLT-enabled Cloud-based SDN Controllers (invited paper)
2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
This paper discusses the advantages and challenges of multiple architectures that consider the negotiation of inter-domain transport network slices using blockchain technologies. To this end, we present results obtained using cloud-native ETSI TeraFlowSDN controller.
Conferences
Dynamic bypass of wavelength switching in SDN-enabled WDM VNTs over SDM Networks with high bit-rate optical channels
2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
We experimentally demonstrate an SDN architecture for WDM VNTs to offload pass-through high bit-rate optical channels from overloaded ROADMs by provisioning spatial channels between the source and destination ROADM’s add-drop stages, and rerouting the optical channels.

Demo paper: “Demonstration of a Scalable and Efficient Pipeline for ML-based Optical Monitoring”
2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
We demonstrate a scalable processing of OPM data using ML to detect anomalies in optical services at run time. A dashboard will show operational SDN controller metrics, raw OPM data, and the ML assessment result.

P5: Event-driven Policy Framework for P4-based Traffic Engineering
2023 IEEE 24th International Conference on High-Performance Switching and Routing (IEEE HPSR 2023)
We present P5; an event-driven policy framework that allows network operators to realize end-to-end policies on top of P4-based data planes in an intuitive and effective manner.

Flexible and scalable ML-based diagnosis module for optical networks: a security use case
2023 - Journal of Optical Communications and Networking Vol. 15, Issue 8, pp. C155-C165
To support the pervasive digital evolution, optical network infrastructures must be able to quickly and effectively adapt to changes arising from traffic dynamicity or external factors such as faults and attacks.
Journals
A Machine-Learning-Based Cyberattack Detector for a Cloud-Based SDN Controller
2023 - Applied Sciences, 13(8), 4914
The rapid evolution of network infrastructure through the softwarization of network elements has led to an exponential increase in the attack surface, thereby increasing the complexity of threat protection.

Microservice-Based Unsupervised Anomaly Detection Loop for Optical Networks
2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
Unsupervised learning (UL) is a technique to detect previously unseen anomalies without needing labeled datasets. We propose the integration of a scalable UL-based inference component in the monitoring loop of an SDN-controlled optical network.

Architecture to Deploy and Operate a Digital Twin Optical Network
2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
We propose an architecture to deploy Digital Twin Optical Networks (DTON), which provide a virtual representation of the physical optical network. DTON allow the assessment of specific behaviors before actual implementation in the physical network.

Demonstration of Zero-touch Device and L3-VPN Service Management using the TeraFlow Cloud-native SDN Controller
2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
We demonstrate zero-touch device bootstrapping, monitoring, and L3-VPN service management using the novel TeraFlow OS SDN controller prototype.

Experimental Demonstration of End-to-end NFV Orchestration on Top of the ADRENALINE Testbed
2022 IEEE International Conference on Network Softwarization (NetSoft2022)
This demonstration will showcase the end-to-end orchestration of virtual network functions in the full-fledged ADRENALINE Testbed Cloud Platform expanding from the edge to the cloud.

Experimental Demonstration of Transport Network Slicing with SLA Using the TeraFlowSDN Controller
2022 European Conference on Optical Communication (ECOC2022)
This demo presents the TeraFlowSDN controller as a solution to provide dedicated transport network slices with SLAs. To this end, the demo details how the interface between an NFV orchestrator and the SDN controller can provide transport network slices using protected disjoint paths.
Conferences
Role of monitoring and analytics in next-generation optical networks
2021 European Conference on Optical Communication (ECOC2021)
We study the requirements that Control, Orchestration, and Management (COM) systems for optical networks should fulfil, present a minimal set of components they should implement, and propose our research point of view regarding the future needs for COM systems for optical networks.

Demo paper: Scalable and Resilient Network Traffic Engineering Using Erlang-based Path Computation Element
2021 - VII IEEE Conference on Network Function Virtualization and Software Defined Networks (IEEE NFV-SDN 2021)
Scalability and resiliency are two significant requirements for upcoming beyond 5G networks. As network resource usage is expected to increase, scalability of the control plane handling the required amount of network resources is also necessary.
