摘要： A method and apparatus is described for identifying content in a packet. The method may obtain data sample from the packet where the data sample is in a predetermined window at an initial offset point in the packet. For each offset point, a first stage of processing on the data sample may be performed to identify if the data sample corresponds to potentially relevant reference string. A more focused second stage of processing may then be carried out on the data sample to identify if the data sample corresponds to potentially relevant reference string. Thereafter, an even more focused third stage of processing may be carried out on the data sample to obtain a third stage result. If the data sample passes all three stages of processing, a predefined action is identified which is associated with a reference string corresponding to the data sample.
摘要翻译：描述了用于识别分组中的内容的方法和装置。该方法可以从分组中的初始偏移点处的数据样本在预定窗口中获取数据样本。对于每个偏移点，可以执行关于数据样本的第一级处理以识别数据样本是否对应于潜在相关的参考串。然后可以对数据样本执行更集中的第二阶段处理，以识别数据样本是否对应于潜在相关的参考字符串。此后，可以对数据样本进行更加集中的第三阶段处理，以获得第三阶段结果。如果数据样本通过所有三个处理阶段，则识别与对应于数据样本的参考串相关联的预定义动作。
