Abstract

The invention provides a feature extraction device and a network flow identification method, device and system. After unidentified data flow sent by a flow identification is received, the flow behavior feature of the unidentified data flow is obtained by performing feature extraction on the behavior thereof; and the flow behavior feature is sent to the flow identification device which can identify the unidentified data flow according to the flow behavior feature, so that the efficiency of behavior feature extraction is high and the network data flow identification rate is high.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a feature extraction device, a network traffic identification method, device and system. Background technique [0002] With the rapid development of Internet technology, new applications of the network emerge in an endless stream, and the intelligent management of data flow in the network becomes increasingly important. In order to carry out intelligent management of data flow, it is first necessary to identify the type of data flow. [0003] In the prior art, packet capture processing is performed on the data flow in advance, and then the acquired data packet is manually analyzed offline to identify the application (Application) to which the data flow belongs. However, this manual analysis method in the prior art is highly dependent on human ability and experience, and the efficiency of the analyzed features is not high, and cannot effectively improve the ...
