Big Data Analytics for Cross-Domain Anomaly Detection to Identify Hidden Service-Impacting Patterns in Fiber Access Broadband Networks
-Fibre-to-the-x networks are observed through several operational systems, yet service-impacting degradation often remains hidden because each system describes only a fragment of the end-to-end service. Optical power, line errors, dynamic bandwidth allocation, IP-session behaviour, customer-premises telemetry, topology...
