PREPROCESSING UNIT FOR NETWORK DATA

摘要

A preprocessing unit includes a data receiver to receive a data packet containing packet information, application data, and application data information, a relevance checker to determine relevance of the data packet in dependence on the packet information, an output module to output preprocessor output data, and a first controller to control output of preprocessor output data in dependence on the relevance of the data packet. In order to discard redundant data, thereby reducing the load of the memory, bus, and CPU of the computer system, the preprocessing unit further comprises a redundancy checker to determine redundancy of the application data preferably and a second controller to control output of preprocessor output data in dependence on the redundancy of the application data.
