Abstract

An apparatus (30) method network server (42 43 44 46 48) and system (40) for detecting data patterns in a data stream (37) comprising a plurality of data symbols representing characters of an alphabet said apparatus (30) executing a deterministic finite automata. The apparatus comprises a state transition register (31) comprising a plurality of states (11 12 13 14 15) including a start state (11) and at least one accepting state (14) and state transitions (16a 16b 16c) from an initial state to a destination state triggered by a data symbol of the data stream (37). The apparatus (30) further comprises character position determining means (32) for determining for each data symbol of each state of the state transition register (31) a corresponding character position in the alphabet it further comprises updating means (33) for updating the state transition register (31) to comprise data symbol ranges (18x 18y) for data symbols with corresponding subsequent character positions (18b) in the alphabet triggering transitions to a same destination state. The apparatus (30) also comprises range determining means (34) for determining whether a data symbol of the data stream (37) is comprised in a data symbol range (18x 18y) of the updated state transition register (37) and determining the corresponding destination state (18b) thereof and triggering means (35) for triggering a state transition (16a 16b 16c) from the initial state to the determined destination state for detecting the data pattern.
