<p>In a routing system and a method for managing a rule entry of the routing system, the routing system comprises: a ternary content addressable memory (TCAM) for classifying rule entries into a reference rule entry having both basic information and priority information about a packet to which a rule having a specific priority is applied, and a separate content rule entry having detailed information about a packet to which at least one rule having the same priority is applied, and for storing the classified rule entries; and an auxiliary memory for storing interface bit map information and direction bit map information corresponding to the reference rule entry, and packet forwarding information corresponding to the content rule entry. Accordingly, when at least one rule having the same priority is applied to several interface packets, all rules can be expressed as only two entries, and the TCAM is effective in memory utilization.</p> |
