The Virtual DBA: Virtualizing Passive Optical Networks to Enable Multi-Service Operation in True Multi-Tenant Environments
(2020)This paper presents the concept of virtual dynamic bandwidth allocation (DBA), a method we propose to virtualize upstream capacity scheduling in passive optical networks (PONs), which provides multiple independent virtual ... -
3-stage Hierarchical Quality of Service for Multi-tenant Passive Optical Network
(2019)Passive Optical Networks (PONs) are an economically efficient means of providing high bandwidth services to end users. This is because PONs are multi-point shared access medium, where end-points can share the cost ... -
Joint Dynamic Bandwidth and Queue Management for Upstream SLA-Oriented QoS in Multi-Tenant, Multi-Service PONs
(2020)We devise a PON upstream scheduler that jointly manages intra-ONT and inter-ONT capacity across VNOs. This provides balancing between throughput and delay, providing SLA-oriented QoS supporting low latency 5G applications ... -
A Performance Analysis of Supervised Learning Classifiers for QoT Estimation in ROADM-based Networks
(2019)Machine learning techniques for optimization purposes in the optical domain have been reviewed extensively in recent years. While several studies are pointing in the right direction towards building ... -
Evolution of access network sharing towards software based passive optical network: can virtual OLTs run at full line rate?
(2020)This paper summarises how access network sharing has evolved from physical layer unbundling to fully virtualised architectures. We address one of the crucial question in access network virtualisation: whether fully virtualised ...
