A latency-aware real-time video surveillance demo: network slicing for improving public safety
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessWe report the automated deployment of 5G services across a latency-aware, semi- disaggregated, and virtualized metro network. We summarize the key findings in a detailed analysis of end-to-end latency, service setup time, ... -
Autonomic NFV network services on top of disaggregated optical metro networks
(2019)
Conference report
Restricted access - publisher's policyControl and orchestration of metro network to support dynamic provisioning and reconfiguration of services based on Virtual Network Functions are demonstrated through a CDN example. Interaction among CASTOR MDA, OSM and ... -
Demonstration of latency-aware 5G network slicing on optical metro networks
(Optical Society of American (OSA), 2022-01-01)
Article
Open AccessThe H2020 METRO-HAUL European project has architected a latency-aware, cost-effective, agile, and programmable optical metro network. This includes the design of semi-disaggregated metro nodes with compute and storage ... -
Demonstration of monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe demonstrate a novel agent for optical disaggregated optical networks. When the Monitoring and Data Analytics detects a degradation, it recommends the SDN controller to trigger a network reconfiguration computed by a ... -
Design and assessment of FM-MCFs-suited SDM-ROADMs with versatile spatial group configurations and unified QoT estimator
(Institute of Electrical and Electronics Engineers (IEEE), 2020-11-15)
Article
Open AccessIn this article, we focus on the design of different node architectures suitable for few-mode multi-core fibers (FMMCFs) based networks. Both dimensions, core and mode, open different possible ways to group spatial channels ... -
Distributed architecture supporting intelligent optical measurement aggregation and streaming event telemetry
(Institute of Electrical and Electronics Engineers (IEEE), 2023)
Conference report
Open AccessA distributed telemetry system integrating optical measurement and event data collection is demonstrated. Measurements of optical spectra from Nokia Bell Labs, of optical transponders from ADVA and SDN controller events ... -
Introduction to the ONDM2020 special issue
(Institute of Electrical and Electronics Engineers (IEEE), 2021-06-01)
Article
Open AccessThis JOCN special issue includes extended versions of selected papers that were presented at the 24th International Conference on Optical Network Design and Modeling (ONDM2020), which took place virtually on May 18–21, ... -
Monitoring and data analytics-triggered reconfiguration in partially disaggregated optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe present ADONIS, which stands for Aggregator/Disaggregator for Optical Network equIpmentS, a novel open device agent able to construct logical network devices from (dis)aggregation of physical components in order to ... -
The dichotomy of distributed and centralized control: METRO-HAUL, when control planes collide for 5G networks
(2019-07)
Article
Open AccessAutomating the provisioning of 5G services, deployed over a heterogeneous infrastructure (in terms of domains, technologies, and management platforms), remains a complex task, yet driven by the constant need to provide ... -
Towards an SDN/NFV-based multi-tenant network and cloud testbed for end-to-end 5G services
(Wireless World Research Forum (WWRF), 2015)
Conference report
Open Access5G has a main requirement of highly flexible, ultralow latency and ultra-high bandwidth virtualized infrastructure in order to deliver end-to-end services. This requirement can be met by efficiently ...
