SYSTEM AND METHOD FOR ERROR DETECTION AND TROUBLESHOOTING ANALYSIS IN A NETWORK OF NETWORK COMPONENTS

摘要

The invention relates to a system (100) for error detection and troubleshooting analysis in a network (200) consisting of a plurality of network components (220, 240, 260, ... N) having software modules (300) and communication interfaces (400) and network nodes (520, 540, 560, ..., M), which are connected to the network components (220, 240, 260, ..., N) by means of communication connections (500). The network components (220, 240, 260, ..., N) and/or the network nodes (520, 540, 560, ..., M) are designed to generate data, which are stored as a quantity of historical data, and to form event sequences from the quantity of historical data consisting of a sequence of events (a, b, c, d, e, f, g). According to the invention, the system (100) is designed to extract those event sequences from the event sequences which end with an alarm event (a), to extract relevant events in turn from said event sequences having an alarm event (a) for an error analysis and to construct reduced event sequences from the relevant events, and, for each reduced event sequence, to construct an automaton (700) for detecting said reduced event sequence.
