DPI (Deep Packet Inspection) technology is a traffic detection and control technology based on application layer. When IP packets, TCP or UDP data streams pass through the bandwidth management system based on DPI technology, the system deeply reads the contents of IP packets, reorganizes the application layer information in the OSI seven-layer protocol, thus obtaining the contents of the whole application program, and then shapes the traffic according to the management strategy defined by the system.
