Abstract:
1. An apparatus for controlling traffic according to user, the apparatus comprising: a statistics processing unit setting a total available traffic threshold value on a managed network, measuring traffic volume used according to user, calculating a traffic variation ΔV by using the measured traffic volume, and updating a traffic user list by comparing the calculated traffic variation ΔV, wherein a monitoring time is initialized when the monitoring time is greater than a monitoring cycle, and a comparison is made between a user's real-time maximum traffic usage and a user's maximum traffic usage when the monitoring cycle is greater than the monitoring time, and wherein a user in a secondary position in the traffic user list is configured to be controlled when a user in a primary position in the traffic user list is deleted; a traffic detecting unit determining whether abnormal traffic is generated in a network and transferring a control command according to priority in the traffic user list; a packet controlling unit controlling a user's traffic according to the control command received from the traffic detecting unit; a packet inputting unit receiving packets and transferring the received packets to the statistics processing unit; and a packet transferring unit transforming packets transferred through the packet controlling unit into a format configured to connect to an external network device, and transferring the transformed packets to the external network device.
