Problems solved by technology

[0004] Existing interception technology is only applicable to PSTN network, is to monitor the voice flow in PSTN network, and what transmits in VOIP network is packet data, therefore, this prior art method for listening to voice flow in PSTN network It is completely inapplicable in the VOIP network, that is, it is impossible to effectively obtain the voice data that needs to be monitored in the VOIP network
[0005] In addition, VOIP is only one aspect of IP network applications. In addition to voice services, IP networks also support various types of data services such as text, images, and videos. For these types of services, there is also a need for monitoring, but for the time being There is no monitoring method that can be effectively applied to IP networks

Abstract

The embodiment of the invention discloses a method, a device and a system for network monitoring. The method for network monitoring comprises the following steps: acquiring an exact matching rule by analyzing a monitoring strategy; and selecting received data by using deep packet inspection according to the exact matching rule to obtain a monitoring result, wherein the received data is a service customizing rule obtained by analyzing the monitoring strategy and is obtained by pre-processing data and filtering grouped data. The system for network monitoring comprises a service inspection server and a service analyzing server. The technical scheme of the embodiment of the invention can realize the monitoring of various packet data services transmitted in an IP network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a network monitoring method, device and system. Background technique [0002] Various new communication technologies based on IP (Internet Protocol, Internet Protocol) network have become the hot spot of current research. Voice over IP network transmission (VOIP, Voice over Internet Protocol) technology is to compress and packetize the analog voice stream signal, and transmit it in the form of packet data in the IP network environment, which has irreplaceable advantages of traditional telephone. With the rapid development of communication technology, VOIP network is gradually replacing the traditional Public Switched Telephone Network (PSTN, Public Switched Telephone Network), and has been recognized by more and more people. For security and other reasons, relevant security departments or some special units often need to monitor the internal communication of the network. ...
