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.

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.

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
End-to-End Interdomain Transport Network Slice Management Using Cloud-based SDN Controllers
2022 27th OptoElectronics and Communications Conference (OECC) and 2022 International Conference on Photonics in Switching and Computing (PSC)
In spite of their popularity, developing secure smart contracts remains a challenging task. Existing solutions are either impractical as they do not support many complex real-world contracts or leave the burden to developers for fixing bugs.
Conferences
Multi-layer Transport Network Slicing with Hard and Soft Isolation
2021 Optical Fiber Communications Conference and Exhibition (OFC2021)
We validate the deployment of isolated transport network slices in IP over DWDM network. To this end, an isolated transport network slice is deployed using multi-layer isolation mechanisms based on OpenConfig and ONF Transport API.
Conferences
Optical Network Telemetry with Streaming Mechanisms using Transport API and Kafka
2021 European Conference on Optical Communication (ECOC2021)
We present a streaming mechanism for optical networks based on the Kafka architecture and protocols, to efficiently distribute state and network updates following the upcoming ONF Transport API streaming implementation agreement.

Advances in SDN control for Beyond 100G disaggregated optical networks
2021 European Conference on Optical Communication (ECOC2021)
This tutorial considers the evolution of SDN control for optical transport networks in disaggregated scenarios, focusing on its requirements and challenges when applied to "beyond 100G" networks - term that jointly refers to the use of coherent technology, data rates beyond 100G and the evolution

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.

Field Trial of Programmable L3 VPN Service Deployment Using SDN-Based Multi-domain Service Provisioning over IP/Optical Networks
2021 - IEEE Network, Vol. 35, Issue 6, November/December 2021
Network operators cannot change their footprint to upgrade the entire network to support SDN from scratch. Hence, network operators adapted the original SDN concept into a hybrid SDN approach to have a pragmatic, evolutionary, and economically viable solution.

Workshop paper: “From 5G to 6G Automated and Intelligent SecuriTy: FAST. Cloud-Scale SDN Network Security in TeraFlow”
2021 - EuCNC 2021 - European Conference on Networks and Communications & 6G Summit
TeraFlow proposes a new type of secure, cloudnative Software Defined Networking controller that will radically advance the state-of-the-art in beyond 5G networks by introducing novel micro-services architecture and providing revolutionary features for flow management and optical/microwave network
Conferences
Special session paper: “Autonomous Network Management towards 6G. Cloud-Native SDN Network Management for Beyond 5G Networks with TeraFlow”
2021 - EuCNC 2021 - European Conference on Networks and Communications & 6G Summit
TeraFlow proposes a novel secured transport Software Defined Networking (SDN) controller based on a microservice architecture. The objective is to foster innovation around SDN controller and evolve them to be suitable for beyond 5G networks.
