We study the requirements that Control, Orchestration, and Management (COM) systems for optical networks should fulfil, present a minimal set of components they should implement, and propose our research point of view regarding the future needs for COM systems for 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

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.

In this work, we address this problem and present MITOSIS, a novel approach to practically improve scalability of permissioned blockchains

Scalability and resiliency are two significant requirements for upcoming beyond 5G networks. As network resource usage is expected to increase, scalability of the control plane handling the required amount of network resources is also necessary.

TeraFlow proposes a new type of secure, cloud-native Software Defined Networking (SDN) controller that will radically advance the state-of-the-art in beyond 5G networks by introducing novel micro-services architecture, and provide revolutionary features for both flow management (service layer) an

TeraFlow proposes a new type of secure, cloudnative Software Defined Networking controller that will radically advance the state-of-the-art in beyond 5G networks by introducing novel micro-services architecture and providing revolutionary features for flow management and optical/microwave network

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.

The hierarchical token bucket (HTB) algorithm allows to specify per-flow bitrate guarantees and enables excess bandwidth sharing between flows of the same class. Additionally, it provides capabilities to prioritize the traffic of specific flows, potentially considering their delay demands.

Abstract: Network operators generally aim at providing a good level of satisfaction to their customers. Diverse application demands require the usage of beyond best-effort resource allocation mechanisms, particularly in resource-constrained environments.

Mobile networks support variety of heterogeneous services, including the emergency and mission-critical ones.
