Abstract
A method and system for filtering data packets, is provided. One implementation involves filtering data packets using a set of filters, each filter having a bit mask and corresponding bit values, by categorizing the filters into different groups based on their bit mask value differences, and generating a new mask of bits having corresponding bit values, applying the new mask to the incoming packet to select a filter category for the incoming packet, and filtering the incoming packet by applying the group of filters for the selected category to the incoming packet.
