A method of controlling traffic, particularly, a method of setting and executing a traffic control policy in which a time condition is additionally combined is provided. At any specific step of a network that executes a time-based policy, an execution time point of the time-based policy can be determined. Further, a network service provider can provide various application services to a network user using a time-based policy.

Method of controlling traffic by time-based policy

Provided is a network duplexing apparatus and method. The network duplexing apparatus includes a plurality of network interface units configured to store information of a flow flowing in the network interface units, provide the information of the flow to a master unit when the flow corresponds to an asymmetric flow, and request information of an opposite side flow of the flow from the master unit to receive the requested information, 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.

Method for managing and sharing symmetric flow and asymmetric flow in duplexed network

Provided is a network duplexing apparatus and method. The network duplexing apparatus includes 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 information of an opposite side flow of the flow from the master unit to receive the requested information, 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.

In an environment in which tag readers are installed at a plurality of locations, communication between a tag reader and a terminal including a near field communication (NFC) tag capable of bi-communication with a tag reader is triggered. The tag reader transmits user information and location information which was provided to the terminal to a location information management server so that a service based on the information is provided.

Method and apparatus for obtaining and processing location information with near field communication
