Abstract: A Mid-Level Manager (MLM) network information management system monitors and manipulates the flow of private information on public networks. The MLM system begins by retrieving and storing information about subscribers to the public networks. The MLM also queries the computers of the public networks to obtain information about network configuration and status. Upon receiving network information, the MLM system uses the stored subscriber information to analyze the network information and to determine the subscribers to which the network information pertains. If network information pertains to a subscriber and the subscriber is authorized to receive that information, the MLM systems adds that network information to a subscriber-specific data storage location. In addition, network status information of interest to administrators of the public network is stored in a separate data storage location.
