Abstract

The embodiment of the invention provides a method, device and electronic equipment for determining an associated non-standard VOIP data flow. The method comprises the steps that a network data packet is obtained, and VOIP data flows in the network data packet are determined; a standard VOIP data flow is selected, and start-stop transmission time information of the standard VOIP data flow is determined; a non-standard VOIP data flow corresponding to the start-stop transmission time information is determined; according to data flow statistical feature information of the standard VOIP data flow, the non-standard VOIP data flow corresponding to the data flow statistical feature information is determined according to the non-standard VOIP data flow corresponding to the start-stop transmission time information; the non-standard VOIP data flow corresponding to the data flow statistical feature information serves as the associated non-standard VOIP data flow. According to the method, device and electronic equipment for determining the associated non-standard VOIP data flow, the associated non-standard VOIP data flow of the standard VOIP data flow can be determined, and therefore a basis is provided for the analysis of the non-standard VOIP data flow.

Description

technical field [0001] The invention relates to the technical field of network communication monitoring, and more specifically, relates to a method, device and electronic equipment for determining associated non-standard VOIP data streams. Background technique [0002] Network data flow identification is an important means of network monitoring. With the continuous development of the network, IP (Internet Protocol, the protocol for interconnection between networks) telephones are becoming more and more popular, and a large number of IP data packets carrying voice appear on the Internet. These data packets are called VOIP data packets, corresponding to a call The process we call VOIP data flow. Due to the reduction of the cost of VoIP technology and the convenience of use, more and more fraudsters use VoIP network telephones to carry out telecom fraud, which seriously threatens the property safety of the country and the masses. Therefore, it is particularly important to anal...
