example 1

[0168] like Figure 5 As shown, this example provides a communication system, including user equipment, an area network, a backbone network, a third-party network, and a log correlation server. The user equipment includes mobile user equipment, broadband user equipment, and the like. The area network includes a first-level area network and a second-level area network. The first-level area network may include a metropolitan area network; the second-level area network may include a provincial network. The log association server here is one of the predetermined servers mentioned above.

[0169] The full flow record is one of the aforementioned first type of detection records; the incremental record is one of the aforementioned second type of detection records.

[0170] exist Figure 5 It also includes the exit of the information data center. Usually, the exit of the information data center and the S1 / Gn port of the wireless network are equipped with detection equipment, for e...

example 2

[0194] A long term evolution (Long Term Evolution, LTE) user equipment in the first mobile communication network uses a news application APP to watch a piece of news, and the Sina server providing the news is located in the network of the second mobile communication. In the above case, the access traffic of the user equipment will flow sequentially through the three collection points of the DPI device: the S1 port, the provincial network exit, and the backbone network exit. When the flow passes through the S1 port, the DPI device detects the parsing flag in the data stream and finds that there is no mark, which means that this data stream has not been parsed. Therefore, the DPI device at the S1 port analyzes the stream in detail, recognizes that the stream is Sina News, and analyzes a total of 74 characteristic fields of the stream as required, and forms a full stream record and uploads it to the associated server; at the same time, in the data The number of the DPI device on ...

Abstract

The embodiment of the invention discloses a traffic detection method and device and a detection data processing method and device. The method comprises the steps of detecting whether a detection markis stored at a preset position of a data packet or not; carrying out first class detection on the data packet when the detection mark is not detected, and forming a first class detection record; inserting the detection mark indicating that the detection is finished at the preset position after the first class detection is finished; and sending the first class detection record to a preset server. According to the detection device provided by the embodiment, whether to carry out the first class detection or not can be determined according to the detection mark in the data packet, so the first class detection is prevented from being repeated abundantly, and the redundant detection data generated by repeating the first class detection is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a flow detection method, a detection data processing method and a device. Background technique [0002] A detection device for detecting traffic, for example, a deep packet inspection (Deep Packet Inspection, DPI) device is widely deployed in an operator's network to identify and monitor traffic. A data flow may pass through different locations in the network, and detection devices located in different locations will detect the data flow, resulting in multiple redundant detections and detection data redundancy. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a traffic detection method, a traffic data processing method, and a device. [0004] Technical scheme of the present invention is realized like this: [0005] The first aspect of the embodiments of the present invention provides a traffic detection method, including: [0006] ...
