Abstract: An apparatus for displaying a network state by using a flow-n-rectangular and a method thereof are provided to determine an abnormal state of the network which degrades its performance and to detect harmful or abnormal traffic causing the abnormal state of the network by using simple data which can show abnormal features of the traffic like flow rates of each port section in accordance with connected time, octet rates, or packet rates. An apparatus for displaying a network state by using a flow-n-rectangular comprises a traffic feature extractor(110), a traffic state displayer(120) and a traffic abnormality checker(130). The traffic feature extractor(110) calculates an occupation rate in accordance with traffic features generated according to a certain reference port and time by referring to traffic information collected by an external traffic information collector, and stores the calculated result. The traffic state displayer(120) expresses an abnormal state of the current network through one and more regular tetragons displayed by using the occupation rate in accordance with traffic features of a port under a reference port, a port over the reference port, a flow over a reference time, and a flow under the reference time on an occupation rate coordinate plane by referring to the calculated result stored in the traffic feature extractor(110). The traffic abnormality checker(130) determines an abnormal state of the network according to the position or size of a regular tetragon drawn on the occupation rate coordinate plane, detects and reports the type of an abnormal state and harmful or abnormal traffic if the abnormal state occurs.
