Patent ID: 7313613

Claim:
A protocol diagnostic system, comprising: a data stream monitor component that accesses raw network data and copies at least one protocol specific subset of the raw network data; a diagnostics engine comprising at least one protocol state compressor that analyzes the at least one protocol specific subset of the raw network data, the protocol specific subset of raw network data being correlated with the protocol state compressor, the diagnostics engine determines condition of network connectivity, and the data stream monitor component utilizes at least one lexical rule set associated with the at least one protocol state compressor to determine subsets of the raw network data to copy, that at least one lexical rule set stores at least one of information regarding structure of subsets of the raw network data and protocol specific information, and where the diagnostic engine, upon initialization, stores information associated with protocols to be monitored in that at least one lexical rule set, upon occurrence of a network connectivity problem, stores information associated with additional protocols, and upon correction of the network problem, deletes information associated with selected protocols from the at least one lexical rule set; and an event correlator that receives results of analysis of the protocol state compressor, the event correlator correlates the results to detect a system problem.
