Advances in SDN control for Beyond 100G disaggregated optical networks

Goals and Non-Goals 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 will cover use-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.
