A method and apparatus for processing a plurality of data in a protocol module. The method includes (a) determining priorities of the plurality of data based on information on the plurality of data, and (b) driving a plurality of protocol modules, which process the plurality of data according to a predetermined protocol, based on the priorities determined in (a). Accordingly, it is possible to process the plurality of data at a high rate by constructing a plurality of Internet protocol (IP) layers and a plurality of a transmission control protocol/user datagram protocol (TCP/UDP) layers in a hardware manner without involvement of a processor.
