Abstract: A multi-level flow table search method includes extracting matching information of a data packet when the data packet is received and selecting a keyword from the matching information of the data packet according to flow-table match-field configuration information. The method also includes searching for a match field of each-level flow table in a multi-level flow table starting from a first-level flow table in the multi-level flow table by using the keyword as a search keyword, and matching the search keyword with the match field. If matching of a match field of a current-level flow table is completed, the method includes executing a corresponding instruction, and if the current-level flow table is not a last-level flow table or there is an instruction for executing an action, executing a corresponding action.

Abstract translation: 多级流表搜索方法包括当接收到数据分组时提取数据分组的匹配信息，并根据流表匹配字段配置信息从数据分组的匹配信息中选择一个关键字。 该方法还包括通过使用关键字作为搜索关键字，从多级流表中的第一级流表开始，在多级流表中搜索每一级流表的匹配字段，并匹配搜索 关键字与匹配字段。 如果当前级流表的匹配字段的匹配完成，则该方法包括执行相应的指令，并且如果当前级流表不是最后一级流表，或者存在用于执行动作的指令， 执行相应的动作。
