Method for extracting internet service flow characteristics

Abstract

The invention discloses a method for extracting internet service flow characteristics. A plurality of distributed flow acquirers are arranged and used for acquiring, selecting and purifying an original data sample, uploading the original data sample, and storing the original data sample in a flow data server; on the basis of pure data which is obtained, a flow characteristic extractor extracts or generates network service flow characteristics and establishes a service flow characteristic base so as to manage and maintain the service flow characteristics; and the flow characteristic extractor also selects appropriate service flow characteristics to assist a researcher or a network manager in further analysis, and provides the appropriate service flow characteristics for deep packet inspect (DPI) equipment. The method is innovated and improved in terms of methods for generating and purifying a database to be analyzed and a standard database, and maintaining a characteristic base. The method is simple and easy to operate. The service flow characteristics of a plurality of application programs can be effectively maintained and dynamically optimized and selected; an inclusive relationship between different service flow characteristics can be reflected, and the characteristics of characteristic sequences, in the same service flow, of a plurality of characteristics are represented; and the method has a good popularization application prospect.

Description

technical field [0001] The invention relates to a method for extracting Internet service flow features, more precisely, relates to a feature extraction method applied to Internet service flow context perception and deep packet detection feature word recognition technology, and belongs to the technical field of Internet communication. Background technique [0002] The next generation network can bring rich service experience to users, but its huge network traffic also brings huge challenges to network managers and service providers. In order to ensure network security and provide users with services with guaranteed quality of service, telecom operators have greatly increased requirements for network controllability and manageability. Traffic identification technology is the basis for ensuring network controllability. Only through effective traffic identification can telecom operators accurately grasp the network status, correctly analyze, understand and predict user behavior ...

AI Technical Summary

Problems solved by technology

As for the latter, the speed of updating and reflecting new services by DPI equipment is far from satisfactory due to the fact that the features of new services are only extracted manually at present.

[0006] To sum up, because of its accuracy, DPI-based technology is still the most commonly used method by operators. However, this method is slow to respond to new protocols. How to quickly and automatically obtain the characteristics of the protocol has become a technology in the industry. The new subject that personnel pay close attention to is also the problem to be solved by the present invention
