Abstract
Methods and apparatuses for searching network data for one or more predetermined strings are disclosed. A multi-stage search may be performed by different hardware components. In a first search stage, a first processor may perform a comparison of blocks of incoming data to determine whether the blocks potentially represent the beginning of one of the predetermined strings. If a potential predetermined string is identified, a second processor may perform a further search to determine whether the string matches one of the predetermined strings.
