ABSTRACT:
A stream parser for receiving, parsing, and/or pre-processing network data traffic directly from an incoming unreconstructed data stream. To extract meaningful data from the unreconstructed data stream, the stream parser employs a context switch module for re-forming parts of packet headers as the data stream is streaming through the stream parser. The stream parser includes a logic unit operated by microcode stored in a program module, as well as a channel configuration memory controlled by software in a master processor. Because of this combination of hardware processing and software control, the stream parser is both quick and flexible.
