3-stage Hierarchical Quality of Service for Multi-tenant Passive Optical Network
Ruffini, Marco (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 ... -
Capacity sharing approaches in multi-tenant, multi-service PONs for low-latency fronthaul applications based on cooperative-DBA
Ruffini, Marco (2020)We propose and compare algorithms to allocate upstream PON capacity, where multiple virtual operators generate independent frame-level allocation over shared infrastructure. Our fragmentation-based approach shows the ... -
Coordinated fibre and wireless spectrum allocation in SDN-controlled wireless-optical-cloud converged architecture
Ruffini, Marco (2019)We provide an experimental demonstration of LTE multi-cell resource allocation in a converged LTE-over-PON architecture. Our SDN controller dynamically adjusts the wireless bandwidth of each cell, according to their ... -
Cost Analysis of Rural Roll-Out using long reach PON: Trading off Upfront Cost Under Uncertainty of User Take-up Rate
Ruffini, Marco (2021)High deployment cost with respect to expected revenue is the main barrier to fiber-to-the-home (FTTH) roll-out in rural areas. This problem, as shown in this paper, is exacerbated by the uncertainty associated with the ... -
Demonstration of Software-DefinedPacket-Optical Network Emulation with Mininet-Optical and ONOS
Ruffini, Marco; Lantz, Bob; Díaz-Montiel, Alan A.; Yu, Jiakai; Rios, Christian; Kilper, Dan (2020)We demonstrate practical software emulation of a software-defined, packetoptical network. Our emulator, Mininet-Optical, models the physical, data plane and control plane behavior, under control of the ONOS SDN controller. -
Deployment Strategies for Protected Long-Reach PON
Ruffini, Marco (2012)The mass deployment of ?bre access networks is probably the most important network upgrade strategy for operators over the coming decade. Next generation networks, and in particular the Long-Reach Passive Optical Network ... -
A Distributed Bilateral Resource Market Mechanism for Future Telecommunications Networks
Ruffini, Marco (2019)In this paper, we propose a distributed market mechanism powered by the blockchain technology addressing network ownership models in multiple telecommunications networks use cases. The proposed model is based on the ... -
Evolution of access network sharing towards software based passive optical network: can virtual OLTs run at full line rate?
Ruffini, Marco (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 ... -
Experimental Demonstration of multiple Disaggregated OLTs with Virtualised Multi Tenant DBA, over General Purpose Processor
Ruffini, Marco (2020)We demonstrate an Optical Line Terminal with fully softwarised data plane and virtual Dynamic Bandwidth Allocation in a sliceable, multi-tenant PON architecture. We evaluate performance results for 6 OLTs sharing the ... -
Full PON Virtulisation Supporting Multi-Tenancy Beyond 5G.
Ruffini, Marco (2019)In this paper, we introduce a virtualization technique to enable fully customizable resource sharing for Passive Optical Networks. We provide a summary of the concept, economic challenges and implementation. -
Hybrid Machine Learning EDFA Model
Ruffini, Marco; Zhu, Shengxiang; Gutterman, Craig; Díaz-Montiel, Alan; Yu, Jiakai; Zussman, Gil; Kilper, Daniel (2020)A hybrid machine learning (HML) model combining a-priori and a-posteriori knowledge is implemented and tested, which is shown to reduce the prediction error and training complexity, compared to an analytical or neural ... -
Joint Dynamic Bandwidth and Queue Management for Upstream SLA-Oriented QoS in Multi-Tenant, Multi-Service PONs
Ruffini, Marco (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 ... -
Moving the Network to the Cloud: the Cloud Central Office Revolution and its Implications for the Optical Layer
Ruffini, Marco (2019)This tutorial provides an overview of the various frameworks and architectures outlining current network disaggregation trends that are leading to the virtualisation/cloudification of central of- fices. The ... -
Next-Generation Fibre to the Home Deployment - A HEAnet Case Study
Ruffini, Marco (2011) -
Optical IP switching
Ruffini, Marco (Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2008)Improvements in the optical transmission technology, over the past fifteen years, have substantially facilitated the development and worldwide deployment of the Internet, by reducing the cost of data transport. The exponential ... -
An Overview on Application of Machine Learning Techniques in Optical Networks
Ruffini, Marco (2019)Today’s telecommunication networks have become sources of enormous amounts of widely heterogeneous data. This information can be retrieved from network traffic traces, network alarms, signal quality indicators, users’ ... -
A Performance Analysis of Supervised Learning Classifiers for QoT Estimation in ROADM-based Networks
Ruffini, Marco (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 ... -
PON Virtualisation with EAST-WEST Communications for Low-Latency Converged Multi-Access Edge Computing (MEC)
Ruffini, Marco (2020)We propose a virtual-PON based Mobile Fronthaul (MFH) architecture that allows direct communications between edge points (enabling EAST-WEST communication). Dynamic slicing improves service multiplexing while supporting ... -
