Abstract

The invention discloses a VoIP association method, device and readable storage medium in an asymmetric routing network. The method includes the following steps: collecting original flow in an asymmetric routing network environment, and extracting the VoIP protocol in the original flow Features; respectively extracting keys associated with the control flow and data flow in the VoIP protocol features; integrating the control flow associated key and the data flow associated key to generate complete VoIP call information. The present invention aims at the problem that the complete description of the VoIP service cannot be realized by only using the deep packet detection technology at present, and realizes the identification and unidirectional flow association of the VoIP control flow in the asymmetric routing network environment, and realizes the identification of the VoIP control flow in the asymmetric routing network environment. A complete description of the VoIP service.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a VoIP association method, device and readable storage medium under an asymmetric routing network. Background technique

[0002] VoIP (Voice over IP) is a technology based on IP packet switching network, through a series of processing such as digitizing, compressing, packing and encapsulating traditional analog voice signals into frames, so that voice services can be carried by IP network. In a complex network environment, the recognition of VoIP services needs to be realized through the deep detection of packets by DPI technology.

[0003] Deep Packet Inspection (DPI) technology is an application-layer-based traffic detection and control technology. When IP data packets, TCP or UDP data streams pass through a bandwidth management system based on DPI technology, the system reads Take the content of the IP packet load to reorganize the application layer information in the ...

Embodiment Construction

[0044] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0045]DPI (Deep Packet Inspection) is a deep packet inspection technology. It is a technology based on application layer traffic identification. Compared with general message identification, it only analyzes the source address, destination address, source port, destination port and protocol type of the data packet. , the deep packet inspection technology goes deeper into the application layer to identify, and can further identify th...
