Problems solved by technology

[0005] The best existing technology is only to distinguish each audio and video stream when capturing packets, save the data packets belonging to different audio and video streams separately, and then splicing the packets belonging to the same stream to form a complete audio Stream or video stream, obtain the encoding information of the stream from the header negotiation of the stream during playback, and then play back the entire stream. If the stream lacks the encoding information of the header, or only obtains a segment of the message in the middle of the stream, it will not work normally. Play back audio and video

Embodiment Construction

[0046] Such as figure 1 As shown, a VoIP audio and video audit method based on network monitoring includes a network sniffing device, which is located between users and users, and mirrors network packets, and the network sniffing device captures network packets The file is stored in the cloud, and the user selects the captured message in the storage cloud to play back; the specific steps are as follows:

[0047] (1) The network sniffing device itself is a network monitoring system based on pattern matching. The network sniffing device monitors the captured network packets. The monitoring process includes the following steps:

[0048] 1) Initialize the configuration of the network sniffing device: read some configuration files, initialize the system; initialize the rule engine; construct a fast rule matching engine;

[0049] 2) Sniff packets in the network;

[0050] 3) unpacking;

[0051] 4) The monitoring engine performs rule matching;

[0052] 5) Analyze the application a...

Abstract

The invention discloses a VoIP audio and video auditing method based on network monitoring. The VoIP audio and video auditing method includes the steps that a network sniffing device is included, the network sniffing device is placed between users, a network message is mirrored out, the network sniffing device stores the grabbed network message into a cloud, and the grabbed message is selected for playback in the storage cloud by the users. By means of the VoIP audio and video auditing method based on network monitoring, the limitation of a current network auditing system is eliminated, the problem that audio and video codes are distinguished in different media streams is solved successfully by grabbing the network message and coding and transmitting message header information, and audio and video real-time playback of both parties of communication can be achieved while network monitoring is conducted.

Description

technical field [0001] The invention mainly relates to the field of audio and video auditing, in particular to a VoIP audio and video auditing method based on network monitoring. Background technique [0002] With the continuous advancement of computer and network technology, the security issues of today's networks are becoming more and more prominent. Whether it is the Internet or the intranet of a company or organization, it has always been a difficult problem to audit the content of network communications. Traditional network packet capture tools can record all packets in the network and review them through various filtering and analysis rules. Audio and video streaming. There are various encoding formats of audio and video streams, and the popular ones are G729, iLBC, iSAC, VP8, etc. However, audio and video are only transmitted in the form of streams in network transmission, and the data stream does not contain codec information. Therefore, although traditional ne...
