Embodiment Construction

[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] The embodiment of the present invention provides a data processing method applied to a DPI device. The execution subject of the method may be a DPI device. The DPI device can detect and identify the data flow, and it can be deployed in the backbone network, the metropolitan area network, and inside the enterprise. Network and other application scenarios, such as figure 1As shown, the DPI device can be directly deployed in a network device link composed of a network card and multiple network devices, so that the data stream output by the network card can be detected and identified by the DPI device and then returned to the next-hop network device. The above-mentioned DPI device may include a processor, a memory, and a transceiver. The p...

Abstract

The invention discloses a data processing method and device applied to a DPI device, and belongs to the technical field of data processing. The method includes: when a target data stream is received,determining a target application layer protocol used by the target data stream; acquiring the target message feature of the target data stream, and identifying a target application type correspondingto the target message feature in combination with a preset identification rule corresponding to a target application layer protocol; and distributing the target data stream to a target processing device corresponding to the target application type. The method and device can improve the processing efficiency of the data stream.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data processing method and device applied to DPI equipment. Background technique [0002] At present, the Internet presents a development trend of high traffic and high bandwidth. Under this development trend, DPI (Deep Packet Inspection, deep packet inspection) equipment has been widely used. DPI equipment is a kind of traffic detection equipment, which is generally deployed at key nodes in the network. It can detect and identify the data flow passing through key nodes, and then send the identification results to the corresponding analysis platform. The analysis platform can analyze the data based on the identification results. Analyze and count the data flow through key nodes. [0003] After receiving the data stream, the DPI device can identify the application layer protocol used by the data stream based on the packets in the data stream, such as FTP (File Transfer ...
