Character string matching library acquired network flow service analysis method and device

Abstract

The invention provides a character string matching library acquisition method and device. The character string matching library acquisition method comprises the following steps: acquiring historical internet surfing flow information of an internet user; analyzing each piece of historical Internet surfing flow information of the user to obtain a first historical character string set, the first historical character string set comprising a first historical character string; merging the same first historical character strings in the first historical character string set, and adding the merged first historical character strings by using traffic to obtain a second historical character string set, the second historical character string set comprising a second historical character string; rankingthe obtained second historical character string according to the flow size; analyzing a service corresponding to the second historical character string; marking the business corresponding to the second historical character string on the second historical character string to generate a third historical character string set; and taking the third historical character string set as a character stringmatching library. The invention provides a network traffic service analysis method and a network traffic service analysis device, which are used for quickly identifying a specific service corresponding to user traffic information.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for analyzing network flow services acquired by a character string matching library. Background technique [0002] In recent years, with the rapid development of the Internet, more and more new network applications have gradually emerged, and the scale of the network has continued to expand. In order to meet the needs of people's daily work and life, the composition of the network has become more and more complex. Network traffic business analysis is an important branch of the communication field. The in-depth analysis and research of Internet traffic is of great significance for network expansion and optimization, network security, and upper-layer user behavior analysis. In recent years, the continuous evolution and development of the Internet has brought new problems and challenges to the business analysis of streaming network traffic. [0003] Today, Internet...

AI Technical Summary

Problems solved by technology

[0003] Today, Internet traffic service identification and analysis methods are relatively mature, but the traditional deep packet inspection (DPI, Deep Packet Inspection) technology service identification only identifies what application (APP, Application) the user uses, and cannot specifically identify the user's use. The specific operation behavior of APP

For example, the traditional DPI can recognize that the user is watching iQIYI videos, but there is often no specific identification of the user's specific behaviors, such as browsing the source of the movie, the type of the movie watched, and the clarity of the movie when watching the movie.
