Abstract: An embodiment of the present document discloses a flow table multi-leveling method, a multi-level flow table processing method and device; wherein the multi-leveling method includes: generating a second flow table, separating a target logic rule in a first flow table and forwarding actions corresponding the target logic rule to the second flow table, to make the first flow table and the second flow table orthogonal to form a ternary content addressable memory (TCAM) flow table; wherein the first flow table saves a plurality of logic rules and all forwarding actions corresponding to the plurality of logic rules respectively; continuously generating new flow tables in the same manner of generating the second flow table, until the number of flow tables reaches a preset upper limit.

Abstract translation: 本文的实施例公开了一种流程表多级平方法，多级流表处理方法和装置; 其特征在于，所述多层次化方法包括：生成第二流表，将第一流表中的目标逻辑规则和对应于目标逻辑规则的转发动作分离到第二流表，使第一流表和第二流表正交 形成三元内容可寻址存储器（TCAM）流表; 其中所述第一流表分别保存与所述多个逻辑规则相对应的多个逻辑规则和所有转发动作; 以相同的生成第二流程表的方式连续生成新的流表，直到流程表的数量达到预设的上限。
