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.

Bahare Masood Khorsandi, Nokia, Germany

Abstract: Coming soon.

Bio: Bahare is part of the Core Architecture Team of Nokia Strategy and Technology based in Munich Germany. Most recently she is actively involved in internal and external 6G projects. She is a PMT member and work package lead in the European-founded project Hexa-X. She is leading a task in the same project dedicated to designing End-2-End system architecture for the next generation of mobile network. She is also a technical contributor in the architecture research group of the Nokia 6G program. Her main interests are Network Analytics and Network Automation topics to which she is contributing in internal projects. 

Bahare received her Ph.D. degree in Electronics, Telecommunication, and Information Technologies Engineering in 2020.  Her Ph.D. title was "Architectures and Algorithms for Reliable 5G Network Design" where she investigated the fundamental resiliency and survivability issues in 5G Radio Access Network architecture. As part of her Ph.D. studies, she was involved in European projects such as "The Royal Gardens Case" project in which she conducted studies related to Centralized and Distributed approaches for the deployment of resilient C-RAN and X-haul. In the "5G Picture" project, she analyzed problems related to the aggregation of Fronthaul and Backhaul traffic in a hybrid switch (IHON).

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.
