OFC is the largest global conference and exhibition for optical communications and networking professionals. The program goes from research to marketplace, from components to systems and networks and from technical sessions to the exhibition. OFC draws attendees from all corners of the globe. OFC 2023 took place in San Diego, California (USA) on 05 – 09 March 2023 and TeraFlow had a lot of activity on this event!

TeraFlow had two invited speakers in Track N “Networks, Applications, and Access” - N3 “Architectures and Software-Defined Control for Metro and Core Networks”

  • Carlos Natalino da Silva, Chalmers University of Technology: “Machine-Learning-as-a-Service for Optical Network Automation”.
  • Ricard Vilalta, CTTC: “End-to-End Interdomain Transport Network Slice Management Using DLT-Enabled Cloud-Based SDN Controllers”.

Teraflow at OCF

On Monday, Hanne-Stine Hallingby from Telenor was asked to virtually share her thoughts and visions about the mobile operator's expectations to transport networks in M2H Panel: “Connectivity for Beyond 5G: How Can Wireline and Wireless Optical Access Live Up to the Mobile Expectations?”. During her virtual presentation “6G vision and the future mobile operator emerging requirements”, she presented some interesting contributions thanks to her recent experience in TeraFlow.

There were two demonstrations related to TeraFlow took place in the Demo Zone:

M3Z.9 “Slice Grouping for Transport Network Slices Using Hierarchical Multi-Domain SDN Controllers”

  • Lluis Gifre Renom, Ricard Vilalta (Presenters), CTTC
  • Juan Carlos Caja-Díaz, Óscar González de Dios, Juan Pedro Fernández-Palacios, Telefónica I+D
  • José-Juan Pedreño-Manresa, Achim Autenrieth, ADVA Optical Networking
  • Mika Silvola, Infinera
  • Nicola Carapellese, Michele Milano, Siae Microelettronica
  • Adrian Farrel, Daniel King, Old Dog Consulting
  • Ricardo Martínez, Ramón Casellas, Raúl Muñoz, CTTC
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.

M3Z.12 “Demonstration of a Scalable and Efficient Pipeline for ML-Based Optical Monitoring”

  • Carlos Natalino da Silva, Presenter, Chalmers University of Technology
  • Lluis Gifre Renom, Raúl Muñoz, Ricard Vilalta, Centre Tecnologic de Telecomunicacions de Catalunya (CTTC/CERCA)
  • Marija Furdek, Paolo Monti, Chalmers University of Technology
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 results.

Five TeraFlow papers have been accepted for this conference:

Demo paper: “Demonstration of a Scalable and Efficient Pipeline for ML-based Optical Monitoring”

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.

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

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.

Dynamic bypass of wavelength switching in SDN-enabled WDM VNTs over SDM Networks with high bit-rate optical channels

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.

End-to-End Inter-domain Transport Network Slice Management Using DLT-enabled Cloud-based SDN Controllers (invited paper)

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.

Demo Paper: "Slice Grouping for Transport Network Slices Using Hierarchical Multi-domain SDN Controllers"

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.
