Abstract
An indexing database utilizes a non-transitory storage medium. A pattern matching processing unit generates preclassification data for the network data packets utilizing pattern matching analysis. At least one processing unit implements a storage process that receives the network data packets, stores the network data packets in at least one of the slots, and transfers the network data packets to a packet capture repository when slots in a shared memory are full. A preclassification process requests from the pattern matching processing unit the preclassification data. An indexing process determines, based upon the preclassification data, whether to invoke or omit additional analysis of the network data packets, and performs at least one of aggregation, classification, or annotation of the network data packets in the shared memory to maintain one or more indices in the indexing database.
