Monitoring a telecommunications network

Difficulties can arise in monitoring a network comprising many users and network elements where direct access to those elements is not available. The invention enables the network manager to accurately monitor operation and model the network by using only transactions built from network traffic between elements. Thus, a module 120 is initialised and configured via an input 161 to define network relationships to be monitored. It receives transaction events from event bus 130. Within the module120, the transactions are analyzed according to the configuration data and results generated according to desired structures and memory for storage of the results. It also provides a query interface for obtaining desired appropriate result information from the memory and outputting the results e.g. to a network management module. By using information obtained from transactions within network traffic, e.g. link set up, protocols etc. the same results can be obtained that needed direct access to network ...
