FEATURE EXTRACTION DEVICE, NETWORK TRAFFIC IDENTIFICATION METHOD, DEVICE AND SYSTEM.

摘要

Embodiments of the present invention provide a feature extraction apparatus, and a network traffic identification method, apparatus, and system. An unidentified data stream sent by a traffic identification apparatus is received, and behavior features of the unidentified data stream are extracted to obtain a traffic behavior feature of the unidentified data stream; the traffic behavior feature is sent to the traffic identification apparatus, so that the traffic identification apparatus identifies the unidentified data stream according to the traffic behavior feature. Therefore, the behavior feature extraction efficiency is high, and the identification ratio of data streams in the existing network is improved.
