We provide an overview of SDN control architectures for WDM over SDM (WDMoSDM) optical networks. We address dynamic management of end-to-end connec- tivity services and WDM virtual network topologies (VNTs) for partially disaggregated multi-domain WDMoSDM networks.

This paper presents and experimentally validates a Blockchain-based architecture to manage End-to-End Network Slice Deployment by stitching Network Slice Subnets in edge/cloud computing domains connected through packet/optical transport networks domains managed by different operators.

We present a cloud-native architecture with a machine learning QoT predictor that enables cognitive functions in transport SDN controllers. We evaluate the QoT predictor training and auto-scaling capabilities in a real WDM/SDM testbed.

We validate the deployment of isolated transport network slices in IP over DWDM network. To this end, an isolated transport network slice is deployed using multi-layer isolation mechanisms based on OpenConfig and ONF Transport API.

This demo shows a cloud-native SDN controller that can estimate end-to-end QoT using both analytical (GNPy) and machine learning algorithms on WDM systems. This transport SDN controller is able to scale horizontally using custom metrics.

Hierarchical Software Define Networking (SDN) architectures is used to manage the co-existence of multiple domains by having an element on top. A collaborative relation-ship between domains, might solve this issue. Blockchain may become the key element for this change to happen.

We propose and demonstrate a set of microservice-based security components able to perform physical layer security assessment and mitigation in optical networks. Results illustrate the scalability of the attack detection mechanism and the agility in mitigating attacks.

We present a streaming mechanism for optical networks based on the Kafka architecture and protocols, to efficiently distribute state and network updates following the upcoming ONF Transport API streaming implementation agreement.

We present the dynamic deployment of logical WDM VNTs by deploying virtual links between ROADM/OXC nodes using spatial channels provided by SDM 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

TeraFlow proposes a novel secured transport Software Defined Networking (SDN) controller based on a microservice architecture. The objective is to foster innovation around SDN controller and evolve them to be suitable for beyond 5G networks.

Network operators have been dealing with the necessity of a dynamic network resources allocation to provide a new generation of customer-tailored applications.
