ABSTRACT:
A system and method of packet classification for advanced packet forwarding using a table-based classification method is implemented using a minimum of additional system hardware. The table-based search process implemented for basic packet forwarding is leveraged to accomplish advanced packet classification through the use of a classification table system and classification information stored in data packets. Packet forwarding decisions may be made based on the result of the classification table search.
