Autonomic NFV network services on top of disaggregated optical metro networks
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 ... -
Autonomic transmission through pre-FEC BER degradation prediction based on SOP monitoring
Conference report
Restricted access - publisher's policyAn Autonomic Transmission Agent based on machine-learning is proposed for excessive bit-error-rate prediction resulting from real-time analysis of state-of-polarization (SOP). The accuracy and speed of the agent enables ... -
Inter-core crosstalk impact on migration planning from elastic optical networks to spectrally-spatially flexible optical networks
(Optical Society of American (OSA), 2019)
Conference report
Restricted access - publisher's policyWe study inter-core crosstalk (ICXT) impact on migration planning toward spectrally-spatially flexible optical networks considering 22-core multi-core fiber. Results reveal that 55-70% of links need to be upgraded when ... -
Automated end to end Carrier Ethernet provisioning over a disaggregated WDM metro network with a hierarchical SDN control and monitoring platform
Conference report
Open AccessThis demo shows how a hierarchical control plane of ONOS SDN controllers orchestrates the dynamic provisioning of end-to-end Carrier Ethernet circuits on a composite network, programming the whole data path from the CPE ... -
Dynamic service reallocation in NFV-based transport WDM optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyFuture network services are expected to deliver additional functionalities besides connectivity. The Network Function Virtualization (NFV) paradigm provides the foundation for such concept. We propose a reallocation-based ... -
Experimental assessment of 5-10Gbps 5G multicarrier waveforms with intensity-modulation direct-detection for PONs
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe sensitivity performance of an IMDDOFDM/FBMC/UFMC/GFDM system with a PIN based receiver is experimentally evaluated for downstream in broadband passive optical networks. Results show sensitivities better than -14.5(-8.0)dBm ... -
SDN-controlled and orchestrated OPSquare DC architecture enabling network slice deployment with QoS guarantees
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyWe present a DC architecture that enables QoSdriven network slices reconfiguration. Per-slice monitoring information is collected; upon potential QoS degradation, reconfiguration of the slice network connectivity is ... -
Enabling data analytics and machine learning for 5G services within disaggregated multi-layer transport networks
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessRecent advances, related to the concepts of Artificial Intelligence (AI) and Machine Learning (ML) and with applications across multiple technology domains, have gathered significant attention due, in particular, to the ... -
Dynamic traffic grooming in Joint Switching (JoS)-enabled flex-grid/SDM optical core networks
Conference report
Open AccessWe propose and evaluate a dynamic traffic grooming strategy enhancing the performance of JoS-enabled Flex-Grid/SDM networks. Results disclose up to 120% and 44% additional carried network traffic vs. no grooming and existing ... -
LUT-Free carrier recovery for intradyne optical DPSK receivers in UDWDM-PON
Conference report
Restricted access - publisher's policyWe present an LUT-free feed-forward carrier recovery architecture in intradyne optical DPSK receivers that reduces ~41% DSP hardware resources and 61% required process clocks with 85% less power consumption in real-time ... -
Time interleaved DPSK/ASK transmitter with directly beat modulated DFB for coherent WDM-PON
Conference lecture
Restricted access - publisher's policyWe experimentally demonstrate a novel low-cost 2.5 Gb/s/¿ transmitter based on a directly modulated DFB laser featuring DPSK/ASK interleaved in time. Rx sensitivity of -44 dBm is achieved at BER=4· 10-3 with 2 dB improvement ... -
Soft failure localization in elastic optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policySoft failure localization to early detect service level agreement violations is of paramount importance in elastic optical networks (EONs), while it allows anticipating possible hard failure events. Nowadays, effective and ...
