Abstract
A system for network traffic analysis comprises a classification engine operable to parse received frames, each frame comprising a plurality of layers of protocols and each frame having a type corresponding to a highest layer protocol or network address of the frame, and to provide pre-analysis of the received frames to generate classification information on a flow-basis and on a per packet-basis, a filter processing engine operable to reduce the received frames based on a type of each frame indicated by the generated classification information to form information representing filtered frames and an analysis block operable to perform detailed analysis on layers of protocols of the filtered frames and generate objects representing the analysis.
