Abstract
System and method for filtering a data packet using a combined filter are disclosed. In one aspect, the method includes receiving a data packet and N filters each comprising a mask and value. 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 further includes generating a common filter mask and the corresponding bit values by taking the overlapping mask bits among portions of the N filters corresponding to the common filter, the common filter being of a length smaller than each filter. The method further includes applying the common filter mask to the data packet to determine whether there is a match between the filtered data packet and each of the N filters.
