Classification: CPC G  H | IPC H

Claim 12:
13. An integrated circuit, wherein the integrated circuit comprises a control circuit and an interface circuit, wherein the control circuit is configured to:
determine, based on distribution characteristics of concerned bits of a plurality of rules in a first rule set, an effective bit corresponding to the first rule set;
determine a hash key value of each rule based on a value of the effective bit of each rule in the first rule set, and store each rule in the first rule set in at least one of S storage units based on the hash key value, wherein the first rule set is any one of N rule sets, the N rule sets are stored in the S storage units, N and S are integers greater than or equal to 1, and effective bits of rules stored in each of the S storage units are the same; and
when traffic classification is performed, search for a corresponding rule in each of the S storage units based on a hash key value of a search key.
