Method for broadband private connection analysis and identification

Abstract

The present invention discloses a method for broadband private connection analysis and identification. The method comprises the steps of: the step 1) establishing a plurality of bandwidth types of daily flow statistics base line, and filtering an abnormal user according to each arranged access bandwidth threshold coefficient; and the step 2) performing subsumption analysis for the identified flowabnormal user, wherein the same network access device, a similar inner and outer layer vlan id and the user side access MAC address are similar, the online and offline time is consistent, the four identification parameters are combined, users who meet the requirement or partially meet the requirement are subjected to grouping and classification; the grouped users are subjected to checking with different priority according to the parameter matching rate to identify the binding private connection users. The method for broadband private connection analysis and identification can identify the single user private connection and multi-user binding private connection.

Description

technical field [0001] The invention relates to a large-bandwidth private connection analysis and identification method based on Radius (broadband user access authentication system) data and DNS (user domain name request data). Background technique [0002] With the speed-up strategy of operators' broadband networks, the bandwidth of home broadband access continues to increase, and incidents of using home broadband bandwidth resources for illegal operations emerge in endlessly, making it impossible to locate network security, and at the same time causing loss of customer resources for operators; bandwidth resale, black operations ( Sell ​​one or more broadband resources to more users), resulting in poor quality of Internet access for end users. The social response is that the operator's network is poor, which affects the operator's brand and reduces customer trust.

[0002] With the speed-up strategy of operators' broadband networks, the bandwidth of home broadband access continues to increase, and incidents of using home broadband bandwidth resources for illegal operations emerge in endlessly, making it impossible to locate network security, and at the same time causing loss of customer resources for operators; bandwidth resale, black operations ( Sell ​​one or more broadband resources to more users), resulting in poor quality of Internet access for end users. The social response is that the operator's network is poor, which affects the operator's brand and reduces customer trust.

[0003] Among them, DPI (Deep Packet Inspection Technology) identifies the number of terminals of a broadband user by monitoring the id sequence of the user's IP protocol layer. There are already cracking technologies and equipment on the network. control;
