ABSTRACT:
Methods and apparatuses are described for inspecting data packets in a computer network. One or more data packets through the network have associated header data and content. One method includes receiving a data packet, examining the data packet to classify the data packet including classifying the data packet using information included in the header and content, determining flow instructions for processing the packet based on both the header information and the content and processing of the packet using the flow instructions.
