BER degradation detection and failure identification in elastic optical networks
(2017-08-30)
Article
Open AccessIEEE Optical connections support virtual links in MPLS-over-optical multilayer networks and therefore, errors in the optical layer impact on the quality of the services deployed on such networks. Monitoring the performance ... -
Dedicated protection with signal overlap in elastic optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2017-11-15)
Article
Restricted access - publisher's policyIn optical dedicated path protection (1 1), the same optical signal is transmitted along both working and backup paths. Thus, in 1 1, the transmission parameters need to be configured according to the most impaired path, ... -
Early pre-FEC BER degradation detection to meet committed QoS
(Optical Society of American (OSA), 2017)
Conference report
Restricted access - publisher's policyEarly optical layer BER degradation detection is proposed to trigger affected demands re-routing, targeting at reducing SLA violation. Results show that the proposed detection and re-routing algorithms noticeably reduce ... -
Filter optimization in SDN-based flexgrid networks
(Optical Society of American (OSA), 2014)
Conference report
Restricted access - publisher's policyThe novel super-filter technique for flexgrid optical networks is proposed to compact spectrum-contiguous lightpaths. The technique is applied in a specifically extended SDN architecture, showing significant gains in terms ... -
Fully disaggregated ROADM white box with NETCONF/YANG control, telemetry, and machine learning-based monitoring
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyA first demonstration of ROADM White Box augmented with machine learning capabilities is demonstrated. The white box includes various level of disaggregation, NETCONF/YANG control, telemetry and spectrum-based advanced ... -
Impact of multi-wavelength sliceable transponders in elastic optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Conference report
Open AccessThe utilization of sliceable bandwidth variable transponders based on multi-wavelength technology is evaluated in EONs. A routing and spectrum assignment scheme is proposed specifically designed to consider the constraints ... -
Routing, spectrum, and transponder assignment in elastic optical networks
(2015)
Article
Open AccessBackbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable ... -
Signal overlap for efficient 1+1 protection in elastic optical networks (EONs)
(Optical Society of American (OSA), 2017)
Conference report
Restricted access - publisher's policyAn innovative transmission technique enabling signal overlap is introduced for spectrally-efficient 1+1 protection. Simulation results show that the proposed technique successfully reduces the overall amount of occupied ... -
Superfilter technique in SDN-controlled elastic optical networks
(Institute of Electrical and Electronics Engineers (IEEE), 2015-02-01)
Article
Restricted access - publisher's policyIn flexigrid elastic optical networks, filtering cascade effects strongly affect the overall transmission performance. To avoid these detrimental impairments, each lightpath is typically configured, in an independent way, ...
