  • System and method for generalized network topology representation
    Patent number: 5684967
    Abstract: System and method for storing in a generalized format, and representing on a graphical user interface, the topology information for a plurality of logical and physical resources in a heterogeneous computer communications network. Topological data for each network resource is encoded using a collection of record structures having a tabular format and stored in a plurality of topology information element tables which are categorized further as data element tables, relationship element tables and auxiliary element tables. The rows in the tables representing discrete data elements are recursively processed and correlated and presented as a generalized topology display via a user interface.
