Patent ID: 8687505

Claim:
An apparatus of controlling a traffic, the apparatus comprising: an interface connector to transmit/receive an Internet Protocol (IP) packet to/from an external circuit; a frame generator to receive the IP packet through the interface connector and to generate a Media Access Control (MAC) frame; and a network processor to transmit/receive the IP packet to/from the frame generator, to examine whether layers of the IP packet satisfy a filtering condition, to identify and classify at least one application corresponding to the IP packet by using a high-speed search function when the layers do not satisfy the filtering condition, and to execute a command to process the IP packet based on a result of the identifying and classifying of the at least one application, wherein the network processor executes the command by: comparing the result of identifying and classifying traffic of the at least one application, and analyzing an original execution code value and a copy execution code value; comparing the original execution code value as a result of the comparing of the result of identifying and classifying the traffic of the at least one application; processing the IP packet based on the original execution code value; comparing the copy execution code value and determining whether a copied IP packet exists; and processing the IP packet based on the copy execution code in response to a packet collapse command of the copy execution code value when the copied IP packet is determined to exist.
