Embodiment Construction

[0039] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0040] Such as figure 1 Shown is a flow chart of a parallel data analysis method applied to a DPI device involved in the prior art. Since the DPI device in the prior art does not have a PCE-E interface, it cannot be externally connected to other processing devices (such as GPUs, graphics processors) that support parallel computing for data calculations. As a result, DPI devices often only process data in a serial manner. , which greatly affects the data processing efficiency. When it comes to the field of data encryption and decryption, it involves feature comparison of a large amount of data.

[0041] Such as figure 1 As mentioned above, the existing technology includes the following steps when processing the traffic data of the a...

Abstract

The invention provides a parallel data analysis method applied to DPI equipment, the method is applied to the DPI equipment, the DPI equipment comprises a PCB circuit board, the PCB circuit board is provided with a card slot, the card slot is electrically connected with the PCB circuit board, and a parallel extension computing device is clamped in the card slot; the method comprises the followingsteps: S1, acquiring an application layer traffic data packet, wherein each flow data packet corresponds to one feature code; S2, classifying the obtained application layer traffic data packets according to the feature codes to determine the type of the current traffic data packet; and S31, when the type of the traffic data packet is a first type, calling a parallel extension computing device to analyze the traffic data packet of the first type to obtain a first analysis result, wherein the first analysis result comprises an application type of a traffic data packet source of a first type. According to the invention, the parallel extension computing device is used for computing the first type of data, so that the data processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of DPI equipment, in particular to a parallel data analysis method and device applied to DPI equipment. Background technique [0002] The current DPI (DeepPacketInspect) technology is the key technology for packet identification in the field of network security. Traditional DPI devices use serial CPUs, and ordinary serial computing CPUs are efficient when decrypting huge data encrypted data packets. low. However, if parallel computing technology is used for data decryption, the efficiency of data decryption will be greatly improved. For example, the efficiency of parallel computing for decryption analysis such as SSL is much higher than that of ordinary serial CPUs, but the cost is relatively high. [0003] As we all know, the serial computing method has very limited ability to decode a large amount of encrypted data, and it will occupy a large amount of computing resources. In terms of analyzing a large number of c...
