Abstract
A method, and corresponding apparatus and system are provided for optimizing matching at least one regular expression pattern in an input stream by walking at least one finite automaton in a speculative manner. The speculative manner may include walking at least two nodes of a given finite automaton, of the at least one finite automaton, in parallel, with a segment, at a given offset within a payload of a packet in the input stream. The walking may include determining a match result for the segment, at the given offset within the payload, at each node of the at least two nodes. The walking may further include determining at least one subsequent action for walking the given finite automaton, based on an aggregation of each match result determined.
