Leveraging SDN and NFV for Pervasive Edge Computing: Challenges and Opportunities
Abstract: With the rapid increase in traffic originating at the edge of the internet, the edge computing paradigm will become an important tool in the chest of network engineers to meet the needs of the traffic. The inherent features provided to applications by edge computing—low latency, privacy, and efficient data handling—makes computing at the network’s edge especially attractive. To further utilize edge computing and to democratize the process of using devices at the edge, the concept pervasive edge computing (PEC) was proposed. A PEC Ecosystem democratizes the landscape of edge devices that can perform computing by allowing any capable device (user, infrastructure) to join the computing ensemble. But, this also significantly increases the number of devices that need to be managed at the edge. This is where the software defined networking and network function virtualization concepts and deployments can be leveraged to make the PEC ecosystem more tractable and efficient. In this talk, we will discuss the opportunities that the use of SDN and NFV can provided in the PEC. We will conclude with a discussion of the challenges in the use of SDN and NFV for PEC.

The architecture for 6G which connects the three worlds
Abstract: The rapid evolution of wireless communication technologies has paved the way for the development of the next generation of cellular networks. Building upon the foundations laid by its predecessor, 5G, 6G aims to deliver unprecedented levels of connectivity, data rates, and latency reduction, catering to the diverse requirements of emerging applications such as network-as-a-sensor, the AI-native air interface, as well as mixed reality (XR), and autonomous systems. 6G is no longer a long-term aspiration. It is a framework of technologies that will become a reality by the end of the decade. We are transitioning from the idea-generation phase to systematization and proof-of-concept realization. This talk is dedicated to presenting the latest progress on many of the key technologies in the 6G ecosystem and the envision for future 6G systems from Nokia perspective.

SDN Control of Disaggregated Optical Networks
Abstract: This talk reports on the state-of-art, current trends, potentials and limitations of the SDN control applied to disaggregated optical networks. The utilization of disaggregated equipment in optical transport networks is emerging as an attractive solution to bring flexibility and prevent network operators from vendor lock-in dependencies. The disaggregation concept can be applied vertically (as in the most traditional SDN approach) to separate the control plane from the data plane, and horizontally aiming at decomposing the optical data plane in its single components. The first step for enabling a vertically disaggregated optical network is the standardization of well-defined interfaces between the data plane and the network controller, thus bypassing proprietary network management systems. To this end, relevant work is ongoing in the definition of multi-source agreements and YANG models for disaggregated devices. This way, an SDN controller could build on standard YANG models and procedures to consistently control, configure and monitor the optical network. This approach also enables operators and service providers to rapidly innovate the offered services through the implementation of specific applications on the top of the SDN controller. Horizontal disaggregation presents the data plane as a set of terminal devices (i.e., transponders) and Optical Line Systems (OLS). With this solution, the operators are enabled to independently upgrade transponders, which typically have a shorter technological life-cycle. Alternatively, the data plane can be disaggregated in transponders and reconfigurable optical add-drop multiplexers (ROADMs) or even ROADMs degrees.
