Claim Text:
1. A network duplexing apparatus comprising: a plurality of network interface units configured to store information of a flow flowing in the network interface units when the information of the flow is not generated, provide the information of the flow to a master unit when the flow corresponds to an asymmetric flow, and request and receive information of an opposite side flow of the flow from the master unit; and the master unit configured to store the information of the flow provided from the network interface unit, determine whether the information of the opposite side flow of the flow is stored, and provide the information of the opposite side flow to the network interface unit when the information of the opposite side flow is stored, wherein, when information of a flow including an SYN packet corresponding to an SYN-ACK packet is not stored in the network interface unit in a case in which the SYN-ACK packet flows in, the network interface unit recognizes that the flow corresponds to the asymmetric flow.
