The service classifying unit 11 is configured to determine a service data type of the user terminal according to the obtained service request instruction of the user terminal. The wave code generating unit 12 is connected to the service classifying unit 11 in communication, and is configured to generate a wave code corresponding to a wave code frequency according to the service data type. The streaming server 20 includes: a matching unit 21 and a data transfer unit 22. The matching unit 21 is in communication connection with the wave code generating unit 12, and is configured to determine a server corresponding to the user terminal according to the wave code frequency of the wave code generated by the wave code generating unit 12. The data transmission unit 22 is in communication connection with the matching unit 21, and is used for transmitting data of a server corresponding to the user terminal.
The user terminal sends a service request to acquire data corresponding to the service request from the server. The service data type corresponding to each server is different, and the service data type is the data type of the data requested by the user service request instruction, for example, the data type is a floating point type, a character type, and the like. After determining the data type of the user terminal, the wave code generating unit 12 generates a wave code of a corresponding wave code frequency according to the service data type, so as to determine a corresponding server according to the wave code. When a plurality of user terminals simultaneously carry out service requests, a server corresponding to each user terminal is determined according to the service data type of the service requests.
When the service request is transmitted to the server, the service request is transmitted according to the wave code. After determining the service data type, the service classification unit 11 sends the service data type to the wave code generation unit 12, and the wave code generation unit 12 is connected to the service classification unit 11 through a signal line. After receiving the service data type, the wave code generating unit 12 generates a wave code corresponding to the wave code frequency according to the service data type.

The service classification modules 111 have the same function, and are commonly used for determining the service data type of the user terminal according to the service request instruction of the user terminal. Service requests of a plurality of user terminals are randomly distributed to different service classification modules 111 to determine the service data type of each user terminal. The traffic monitoring module 112 monitors the user amount processed by all the service classification modules 111, and when the user amount exceeds the maximum user amount that the service classification module 111 can bear, the user of the service classification module 111 is dispatched to other service classification modules 111, so as to avoid the excessive user amount processed by the service classification module 111, and improve the processing efficiency.
In some embodiments, the traffic monitoring module 112 is further configured to monitor CPU occupancy of the service classification modules 111, and perform user scheduling between the service classification modules 111 according to the CPU occupancy of each service classification module 111. Wherein the CPU occupation of the service classification module 111 is related to the amount of data processed by the service classification module 111. When the data volume processed by the service classification module 111 is too high for the CPU occupation of the service classification module 111, the user of the service classification module 111 is allocated to other service classification modules 111, so as to reduce the CPU occupation of the module and improve the processing efficiency.
