Abstract
A DFA engine is described that determines whether a current symbol of a payload matches a label of any effective arcs or negative arcs associated with a current node of a DFA graph that are stored in a cache. Responsive to determining that the current symbol does not match a label of any effective or negative arcs associated with the current node of the DFA graph, the DFA engine determines whether the current symbol matches a label of any arc associated with the current node of the DFA graph that is stored in a memory. Responsive to determining that the current symbol matches a label of a particular arc associated with the current node of the DFA graph that is stored in the memory, the DFA engine stores the particular arc in the cache as a new effective arc and uses the particular arc to evaluate the current symbol.
