Using 5G QoS Mechanisms to Achieve QoE-Aware Resource Allocation
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.
SDN Control Architectures for WDM over SDM (WDMoSDM) Networks
in Proceedings of Photonics in Switching and Computing Conference, 27 -29 September 2021, virtual event.
HTBQueue: A Hierarchical Token Bucket Implementation for the OMNeT++/INET Framework
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.
Role of monitoring and analytics in next-generation optical networks
Packet Optical Transport Network Slicing with Hard and Soft Isolation
Network operators have been dealing with the necessity of a dynamic network resources allocation to provide a new generation of customer-tailored applications.
First Demonstration of Dynamic Deployment of SDN-enabled WDM Virtual Network Topologies (VNTs) over SDM networks
Optical Network Telemetry with Streaming Mechanisms using Transport API and Kafka
Field Trial of Programmable L3 VPN Service Deployment Using SDN-Based Multi-domain Service Provisioning over IP/Optical Networks
Network operators cannot change their footprint to upgrade the entire network to support SDN from scratch. Hence, network operators adapted the original SDN concept into a hybrid SDN approach to have a pragmatic, evolutionary, and economically viable solution.
Scalable Physical Layer Security Components for Microservice-Based Optical SDN Controllers
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.
Special session paper: “Autonomous Network Management towards 6G. Cloud-Native SDN Network Management for Beyond 5G Networks with TeraFlow”
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.
