    • A method includes receiving a data unit, determining whether a current state, associated with a deterministic finite automata (DFA) that includes a portion of states in a bitmap and a remaining portion of states in a DFA table, is a bitmap state or not, and determining whether a value corresponding to the data unit is greater than a threshold value, when it is determined that the current state is not a bitmap state. The method further includes determining whether the current state is insensitive, when it is determined that the value corresponding to the data unit is greater than the threshold value, where insensitive means that each next state is a same state for the current state, and selecting a default state, as a next state for the current, when it is determined that the current state is insensitive.
    • 一种方法包括接收数据单元,确定与包括位图中的状态的一部分和DFA表中的剩余部分状态的确定性有限自动机(DFA)相关联的当前状态是否为位图状态, 以及当确定当前状态不是位图状态时,确定对应于所述数据单元的值是否大于阈值。 该方法还包括当确定对应于数据单元的值大于阈值时确定当前状态是否不敏感,其中不确定意味着每个下一状态对于当前状态是相同的状态,并且选择 默认状态,作为当前的下一状态,当确定当前状态不敏感时。
