Intelligent traffic scheduling method and system based on DPI and diverter

The invention relates to the technical field of network traffic distribution, in particular to an intelligent traffic scheduling method and system based on a DPI and a diverter. The method comprises the steps: analyzing broadband traffic through the DPI to obtain user attribute information, and further building a corresponding relation between IP information of a user and non-IP information; whenthe flow of the target group needs to be filtered out, converting the non-IP information of the target user into IP information based on the non-IP information of the target user and the correspondingrelation; generating a filtering rule in real time according to the IP information of the target user, and issuing the filtering rule to the shunt; and the flow divider performing filtering on the BRAS flow according to the filtering rule, and outputting the obtained target flow to a DPI device for flow analysis. According to the invention, when the IP of the target user is unknown or unfixed, the filtering rule can be dy
