Network Applications: Opening up 5G and beyond networks

5GPPP - Software Network Working Group
As part of the 5G-PPP Initiative, the Software Network Working Group prepared this white paper to demystify the concept of the Network Applications. In fact, the Network Application ecosystem is more than the introduction of new vertical applications that have interaction capabilities.

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.

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.

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.

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.

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.

Dynamic Reconfiguration of WDM Virtual Network Topology over SDM Networks for Spatial Channel Failure Recovery with gRPC Telemetry

2022 Optical Fiber Communications Conference and Exhibition (OFC2022)
We experimentally demonstrate the dynamic reconfiguration of WDM VNTs in response to SDM spatial channel failures. We present an SDN control architecture with gRPC-telemetry and analytics to detect failures and restore failed virtual WDM links.

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.
