Step 209, the service information database (103) sends a parameter response required by configuration generation to the configuration generation interface (104).
Step 210, the configuration generation interface (104) generates a service level information flow according to the parameter response required by configuration generation, and sends the service level information flow to the service request interface (101), wherein the service level information flow comprises server level information.
Specifically, the server level information includes service level information of a corresponding APP, and is represented by a field priority; and SDN path information corresponding to the APP service is expressed by S.SITE/D.SITE.
