Abstract

A network processing system uses intelligent security hardware is a security accelerator at its front end. The security hardware performs initial processing of incoming data, such as security detection tasks. The security hardware is directly connected to one or more processing units, via a bus or switch fabric, which execute appropriate applications and/or storage programming.
