Packet processing method and toe hardware

Abstract

Provided is a TOE hardware which includes intrusion prevention system hardware for inspection and real-time interrupt against static/dynamic attacks over network as well as fast TCP/IP processing, and a packet processing method in the TOE hardware. When a network packet is received, it is segmented to extract a header and a payload. A pattern matching inspection is performed for the payload, and the payload passed the inspection is transferred to the host. For the header, a header inspection is performed and a TCP/IP processing is performed on the header passed the inspection. Processing on the payload is performed in parallel with processing on the header. Accordingly, the packet processing speed of the TOE hardware increases.
