Method for providing information on network status from telecommunication networks

A method for providing network status information comprising: - splitting the service provider's network into multiple overlay levels, from a lowest overlay level 0 to a highest overlay level n; - at the lowest overlay level 0, collecting network status information from network elements of the service provider's network and communication devices connected to the network elements of the service provider's network; - for each overlay level i, from a lower overlay level i=1 to a higher overlay level i=n-1, collecting network status information from the network elements connected at the overlay level i and filtering the network status information collected at previous overlay levels j, j= 0, 1,...i-1, to generate events and aggregate them based on an identity and a value of each event; - broadcasting the aggregated events in cascade, from overlay 1 to overlay n-1; - exposing through publish-subscribe the broadcasted information to the consumer at the highest overlay level n.
