Advances in SDN control for Beyond 100G disaggregated optical networks

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 of OTN standards to support rates such as 200G, 400G, or 800G.The tutorial cover suse-case driven SDN development, new challenges and requirements such as the need to account for physical impairments, multiband / SDM control, improved fault/alarm management, network sharing or optical telemetry and streaming.
