Embodiment 1

[0027] Such as figure 1 and 2 As shown, the embodiment of the present invention provides a multi-standard 10Gbps network signal long-term acquisition and playback system, including: industrial computer, 10GE / 10G SDH high-speed network card and SSD high-performance memory card, and the industrial computer is connected through PCI-E The interface is connected to the 10GE / 10G SDH high-speed network card and the SSD high-performance memory card; the 10GE / 10G SDH high-speed network card is connected to the data source through an optical fiber;

[0028] The SSD high-performance memory card includes a plurality of FPGAs, and each controller is respectively connected with a plurality of NAND FLASH chips and DDR.

[0029] In the present invention, in order to realize system integration, the hardware structure adopts the form of an integrated portable industrial computer plus a function expansion card. The main platform is an industrial computer with a built-in display and keyboard, a...

Embodiment 2

[0042] The embodiment of the present invention provides a multi-standard 10Gbps network signal long-term acquisition and playback method, using the multi-standard 10Gbps network signal long-term acquisition and playback system described in Embodiment 1, including the following steps:

[0043] S1, 10G Ethernet or 10G SDH signals are connected to the high-speed network card through optical fiber, and the high-speed network card collects, aggregates and distributes high-speed signals of different specifications according to corresponding strategies;

[0044] S2, after the distributed high-speed signal reaches the memory of the industrial computer through DMA, the operating system uses multi-threading and ring buffer to receive and process the high-speed signal respectively, and store it in the SSD high-performance memory card;

[0045] S3, adopts the method of multithreading to read the file, and caches the read data in the memory of the industrial computer in blocks;

[0046] S4, ...

Abstract

The invention discloses a system and method for long-time acquisition and playback of multi-specification 10Gbps network signals, relating to the technical field of high-speed network signal acquisition and playback. The system and method can simultaneously achieve the acquisition and playback of high-speed network signals with various specifications such as 10Gbps Ethernet and 10Gbps SDH, and cansolve the previous single-specification signal acquisition and playback mode. At the same time, by adopting a high-speed large-capacity high-performance SSD memory disc and a multi-threading technology, the system can achieve long-time line speed acquisition and playback of 10Gbps network signals, and the acquired signals can be continuously stored in real time. In addition, the system provides afunction of playing back the signals according to the line speed and a timestamp or in a constant-speed mode, can also specify the number of data playback times, ensures that a default playback modeis an infinite loop playback mode, and further provides various methods for data signal analysis.

Description

technical field [0001] The invention relates to the technical field of high-speed network signal acquisition and playback, in particular to a system and method for long-term acquisition and playback of multi-standard 10Gbps network signals. Background technique [0002] A long-term acquisition and playback system with multi-standard high-speed network signals is crucial to the analysis, screening and extraction of network signals. [0003] At present, the existing high-speed network signal collection and playback system, on the one hand, the signal specifications it can adapt to are relatively single, and can only collect and play back a certain type of network signal; on the other hand, for high-speed network signals, only the The signal is collected into the memory and then slowly saved to the disk. However, the standard tester has a small memory and cannot continuously collect, store and playback for a long time, nor can it send messages with rich content and large files....
