Problems solved by technology

[0004] In the above message playback, the server can only play back one data message at a time, which causes the DPI device to perform DPI testing based on only one data message at the same time, resulting in low efficiency of DPI testing
At the same time, the source address and destination address of each data packet in the DPI test of the DPI device are the same, the DPI test is single, and the test effect is poor

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] Currently, software such as Tcpreplay is used to play back packets for DPI testing. In this kind of message playback mode, the server can only play back one data file at a time, which causes the DPI device to perform DPI testing only according to one data message at a time, resulting in low efficiency of DPI testing. At the same time, the source address and destination address of each data packet for the DPI test performed by the DPI device are the same, the DPI test is singl...

Abstract

The embodiment of the present application provides a message playback method and device. The method includes: determining the file to be played back, and extracting the load information of each data message in the file to be played back; Protocol-type message headers, and establish threads corresponding to the preset number of source addresses; use the message headers corresponding to each source address in the preset number of source addresses, and encapsulate the extracted payload information respectively, Obtain the preset number of reconstructed data packets corresponding to each load information; use the thread corresponding to each source address in the preset number of source addresses to send each reconstructed data packet to the DPI device, so that the DPI device according to the received The DPI test is performed on each reconstructed data packet. By applying the technical solution provided by the embodiment of the present application, the efficiency of DPI testing can be improved, and the effect of DPI testing can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message playback method and device. Background technique [0002] With the development of network technology, malicious behaviors that threaten network security have become increasingly complex, and many malicious behaviors are even hidden in the application layer payload of data packets. This makes the DPI (Deep Packet Inspection, deep packet inspection) function more and more indispensable, and the DPI test is also becoming more and more important. [0003] At present, the DPI test mainly uses software such as Tcpreplay to play back packets. Specifically, the server running Tcpreplay software obtains files to be played back (such as pcap files). The pcap files include a plurality of data packets, and the source address of each data packet in the pcap files is rewritten as the address of the server. The destination address of each data packet is rewritte...
