ABSTRACT:
A filter for processing a packet can have a plurality of first masks for masking the packet, and a storage unit configured to correspond to the plurality of first masks for storing a first bit map. In addition, the filter can have a first table configured to apply the first bit map thereto. If upon applying the first bit map to the first table results in a match, then at least one specified action is implemented on the packet.
