Diagnosing data communication networks.

摘要

An expert system (102) for diagnosing data communication networks (142). The expert system (102) operates according to a landmark data abstraction paradigm, wherein landmarks (2402) are interpretations of network data (2304). The landmarks (2402) are indicators of network problems (2302). The expert system (102) diagnoses the data communication networks (142) by detecting landmarks (2402) and then interpreting the detected landmarks (2402) to determine whether network problems (2302) exist.
