Content Recognition network is the management of network to the transport layer to the application layer. If a switch is able to unlock each layer of packets through each tier of packets, and identify the deepest information, then it has the content recognition function. In order to solve the problem of distinguishing application, dynamically allocating resources and billing of users, it is a good way to use network to identify devices to distribute traffic. Some of the content-recognition devi
