The growing popularity of the Internet brought the broadband steal

IDC transmission and other issues

which affected the healthy and stable development of the Internet market so it was not conducive to safety control. According to the adverse effects of private broadband access to the Internet

the paper put forward a solution of prevention of bandwidth steal based on the deep packet inspection technology. A solution based on deep packet inspection was proposed to prevent bandwidth steal. It could analyze

assign weights from multiple dimensions and summarize

rank and audit possible private IP based on scores. So the solution can effectively identify bandwidth steal and IDC transmission phenomena

which adds new ideas and technical means for the control of bandwidth steal.
