Abstract :
In this letter we show a fault localization system implemented by using policy-based thresholds for triggering alarms or self-healing mechanisms. Alarms are collected and organized within a codebook, which is a fundamental component of our fault management system. The relevant performance is analyzed by using a real network deploying VoIP services.
