摘要：System and method for filtering a data packet using a combined filter aredisclosed. In one aspect, the method includes receiving a data packet and N filters. The

method includes receiving a data packet and N (wherein N is an integer and N>1) filters,each filter comprising a bit mask and corresponding bit values. The method furtherincludes, for each of the N filters, identifying a key element from a portion of the filtercorresponding to a combined filter, the key element being a segment of the filterportion having the. richest bit pattern. The method further includes generating thecombined filter by combining the key element of the N filters. The method furtherincludes filtering the data packet with the combined filter to determine whether there isa match between the data packet and each key element.
