Abstract

The present invention provides a verification method, system and DPI device of a DPI device identification result, including detecting whether there is a client that has established a connection on the source IP address of the target data flow; when there is a client that has established a connection on the source IP address The terminal sends the quaternion information of the target data stream to the client; receives the process name sent by the client; obtains the matching application protocol according to the process name sent by the client; Verify whether the matching application protocol is the same as the application protocol identification result of the DPI device. The verification method, system and DPI device of the present invention can determine whether the application protocol fed back by the client is the same as the application protocol recognition result of the DPI device, and collect information related to abnormal data streams when the two are different , to realize the extraction of feature information of the application protocol and the establishment of a feature library.

Description

Technical field[0001]The present invention relates to the technical field of information processing, in particular to a method, system and DPI device for verifying DPI device identification results.Background technique[0002]DPI (Deep Packet Inspection, deep packet inspection) is a 7-layer protocol analysis technology that matches application protocol features by parsing application layer data (including IP / TCP / UDP packet header and payload content) to determine A data flow identification method of the application to which the message data flow belongs.[0003]After the DPI device recognizes the application to which the data stream belongs, it can perform precise routing control, QOS control, security control, and analysis and statistics operations on the message according to the needs of the usage scenario. The effect of these operations is very dependent on the accuracy of DPI recognition. The accuracy of DPI recognition mainly depends on the accuracy of the protocol feature library ...
