Multi-pattern packet content inspection mechanisms employing tagged values

Method for testing system lower relative to the search comprises multiple samples, wherein the normally hard realizing. And the high-precision recorder data structure is line realized via the communication multi-sample search of series of character searching algorithm machine. High-precision recorder data structure comprises a symbol and depth of corresponding search of sample definition search displacement. The covering edge covers contacted with classifies And Liu, and memory is the formation of communication. Is provided with one portion is electrically connected with the fixing the current data high-precision recorder structure. During for detecting; the algorithm machine for mark value to receive to/effectively to each sample search of the part of data stream; and when butted with the depth of sample scram the sample search.
