The present invention provides a method of operating a network comprising the steps of: analyzing a first datastore comprising data representing historical network performance; creating or more indices within the first datastore; creating one or more probability networks in accordance with one or more of the created indices; determining from the one or more probability networks a conditional probability associated with an alarm event; and' if the conditional probability determined is less than a threshold value, disregarding the associated alarm event; or if the conditional probability determined is greater than a threshold value, using the associated alarm event in conjunction with other historical network data to predict future alarm events.

Network analysis system

In a network of computers, e.g. the internet, each computer records the information sources it accesses, and these records are used to identify computers whose users share common interests, as indicated by the sources they access. A virtual network is created linking computers whose users have been identified as sharing similar interests data on what sources have been accessed by each user are shared with neighbouring computers, a defined by the virtual network. Computers can also pass on information on sources accessed received from one neighbour to other neighbours.
