NETWORK PACKET PROCESSING DEVICE AND A METHOD THEREOF CAPABLE OF SOLVING THE PERFORMANCE DEGRADATION PROBLEM OF A PACKET PROCESSING PROCEDURE

摘要

PURPOSE: A network packet processing device and a method thereof are provided to process packets in which packet data is successively updated by updating a processing rule by receiving a packet inspection result.;CONSTITUTION: A packet processing unit(130) generates an initial processing rule when a system is initialized. The packet processing unit stores the generated processing rule in a rule storage unit. The packet processing unit generates a copy packet. The packet processing unit requests the inspection of the generated copy packet to the packet inspection block. The packet processing unit processes a stored original network packet in packet buffer according to the processed rule in the rule storage unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Packet buffer; (120) Rule storage unit; (130) Packet processing unit; (140) Packet inspection block; (141) Packet inspection unit 1; (14N) Packet inspection unit N; (151) Packet counter 1; (15N) Packet counter N; (AA) Incoming packet; (BB,DD) Rule; (CC,EE) Packet; (FF) Completion packet
