[0042] Distinguishing or identifying data streams belonging to different applications in aggregated traffic can facilitate network management, such as providing different service guarantees for traffic of different applications.
[0043] Usually, DPI technology is used to classify data streams by application. During the process of traffic forwarding, the DPI device extracts traffic features based on the byte information in the data stream, and then matches the extracted traffic features with the preset identification rules to obtain classification results. Since the identification rules used by DPI devices to classify traffic need to be summarized and obtained by technicians, it is time-consuming and laborious, and it is difficult to meet the problem of unidentifiable data streams caused by application updates. In addition, since the extraction of traffic characteristics is based on the byte information in the data stream, it is difficult to extract the traffic characteristics...
