Chandler, Arizona, USA (hybrid event)

The 8th IEEE Conference on Network Functions Virtualization and Software-Defined Networking (IEEE NFV-SDN 2022) fostered knowledge sharing and discussion on new approaches as well as work addressing gaps and improvements in NFV and SDN-enabled architectures, algorithms and operational frameworks for virtualized network functions and infrastructures. The conference took place onsite and hybrid from 14-16 November 2022.

IEEE NFV-SDN 2022 continued as the premier IEEE event on the latest NFV and SDN concepts and mechanisms. In 2022, the conference focused on the foundation, design, verification, operation, security, and evolution of virtualized network functions (VNFs) and the advances in the NFV concept. In addition, the 2022 conference included an investigation of the relationship Beyond 5G/6G networks and transmission technologies will have with applications within the NFV architectural concepts. Special interest was given to how Beyond 5G/6G applications are designed, orchestrated and managed by NFV mechanisms and VNFs.

Ricard Vilalta and Lluís Gifre (CTTC) presented a hands-on tutorial. This tutorial showed the novel protocols and data models that are arising to control and monitor packet-optical network equipment and offered an overview and hands-on experience on programming the necessary tools to control and monitor the network equipment, while introducing the novel ETSI TeraFlowSDN controller, which is an open-source cloud native SDN controller that enables smart connectivity services for future networks beyond 5G. The event helped to explain that the need bread of cloud-native SDN controllers will allow rapid prototyping and experimentation in research and standardization activities.

During IEEE NFV-SDN 2022, the coordinator of TeraFlow Ricard Vilalta (CTTC) also organized the panel session on “Network Automation in Carrier Networks: Reality vs. Myths”.

The proposed panel presented a fact checking against current state of the art network automation mechanisms and its purpose was to evaluate current deployed and proposed use cases for software defined transport networks. Special attention was given to aspects of network automation such as the exposure of network capabilities (using standard interfaces), as well as the deployment of End-to-End connectivity services. Multiple network technologies were discussed, including network disaggregation, considering whiteboxes that can act as cell site gateways, broadband network gateways and optical transponders. Finally, participants discussed on the current status of cloud-based network automation and proposed solutions for software-defined everything.

There is a video with the presentations of this panel.
