  • Patent number: 5276789
    Abstract: A system for automatically laying out and graphically displaying the topology of a computer network system. The layout system retrieves a list of the nodes within the network and their interconnections from a database which can be manually built by a network administrator or automatically constructed by other software. The system will provide any of three views that can be requested by the user. An internet view is the largest and shows the interconnection of different networks. A network view can be shown for any of the networks described in the internet view. A network is comprised of segments and the system will display a view of the nodes connected to any one of the segments. The system will automatically update the view as new nodes become available in the database. This aspect of the system and allows the system to dynamically update the graph when the list of nodes is being supplied by other software.
