Experimental Demonstration of ML-Based DWDM System Margin Estimation
SNR margins between partially and fully loaded DWDM systems are estimated
without detailed knowledge of the network. The ML model, trained on simulation
data, achieves accurate predictions on experimental data with an RMSE of 0.16

Software-Defined Networks for Future Networks and Services: Main Technical Challenges and Business Implications
In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on "SDN for Future Networks and Services" (SDN4FNS'13) was organized in Trento, Italy (Nov. 11th-13th 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-art, state of standardization, and further discussed the main technical challenges and socio-economic aspects of SDN and virtualization in future networks and services. A number of research and development directions have been identified in this white paper, along with a comprehensive analysis of the technical feasibility and business availability of those fundamental technologies. A radical industry transition towards the "economy of information through softwarization" is expected in the near future
An Alarm Filtering Algorithm for Optical Communication Networks
: A single failure in a communication network can trigger many alarms. We propose an alarm filtering algorithm for the management of an optical network using Wavelength Division Multiplexing (WDM). The algorithm supports: (i) multiple failures and (ii) passive network elements that do not generate alarms but may fail. This algorithm will be applied to the network of the ACTS COBNET project. Keywords: Alarm Filtering, Fault Recognition, WDM Networks, Failure Diagnosis. Submission Area: Performance and Fault Management for broadband networks.
