Processing method for accelerating packet filtering

Abstract

A processing method for accelerating packet filtering is used for accelerating the filtering process of packet data in a computer. The processing method accelerating packet filtering includes the steps. A plurality of packet filtering policies is loaded. Feature values of each packet filtering policy are resolved. A grouping procedure is performed on the packet filtering policies according to the feature values, so as to add the packet filtering policies meeting a threshold value to corresponding policy groups. A performing sequence of the packet filtering policies in the policy groups is determined according to a performing sequence of the packet filtering policies. A performing sequence of the policy groups is determined according to a producing sequence of the policy groups. A plurality of packet data is received. When the packets don't match the policy groups, the default policy is processed according to protocol information of the packets.
