Claim Text:
1. A network duplexing apparatus comprising: a plurality of network interface units, each of which is configured to generate and store information of a flow flowing in a network interface unit when the information of the flow is not generated, and, when the flow corresponds to an asymmetric flow, provide the information of the flow to a master unit and request information of an opposite side flow of the flow from the master unit to receive the requested information; and the master unit communicating with the plurality of network interface units and configured to store the information of the flow provided from a first network interface unit among the plurality of network interface units, determine whether the information of the opposite side flow provided from a second network interface unit among the plurality of network interface units is stored, and provide the information of the opposite side flow to the first network interface unit when the information of the opposite side flow is stored, wherein the plurality of network interface units are network interface cards equipped in each corresponding slot of a board, and the master unit comprises a central processing unit (CPU), and wherein the asymmetric flow is performed through the first and second network interface units.
