Network processing in content inspection applications

Shows how NP can be used for complicated tasks including advanced classification of packets. Advanced classification requires the NP to look beyond the layer 3-4 header of the protocol, deep into the session and application layer payload. Dubbed "content inspection", such advanced classification requires specialized high-performance ICs, and a powerful and sophisticated set of tools for programming the ICs. These tools enable users of advanced classifiers to describe protocols using a high-level formal language, and then build classification policy with the help of an API. Complimented by policy verification and system simulation tools, content inspection will bring the required ease of use and processing power into the hands of communication systems designers.
