P4-based Telemetry Processing for Fast Soft Failure Recovery in Packet-Optical Networks

2023 Optical Fiber Communications Conference and Exhibition (OFC2023)
A novel framework for in-network P4 processing of distributed telemetry data is presented, enabling effective soft failure detection and recovery strategies enforced in just few microseconds.

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.

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.

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.
Conferences

Scalable Physical Layer Security Components for Microservice-Based Optical SDN Controllers

2021 European Conference on Optical Communication (ECOC2021)
We propose and demonstrate a set of microservice-based security components able to perform physical layer security assessment and mitigation in optical networks. Results illustrate the scalability of the attack detection mechanism and the agility in mitigating attacks.

TeraFlow: Secured Autonomic Traffic Management for a Tera of SDN Flows

2021 - EuCNC 2021 - European Conference on Networks and Communications & 6G Summit
TeraFlow proposes a new type of secure, cloud-native Software Defined Networking (SDN) controller that will radically advance the state-of-the-art in beyond 5G networks by introducing novel micro-services architecture, and provide revolutionary features for both flow management (service layer) an
