• generating, by a management server, application feature information associated with an application, wherein
• the application feature information comprises an identifier of the application and an allocated service level, and
• the allocated service level meets a service level requirement of the application;
• generating, by the management server, a control policy based on the application feature information, wherein the control policy comprises a correspondence between the application feature information and an execution action;
• and
• sending, by the management server, the control policy to a network device.

A network device, comprising:

• a processor;
• and
• a memory configured to store computer readable instructions that, when executed by the processor, cause the processor to:
• receive a service packet carrying application feature information, wherein the application feature information is associated with an application;
• determine a control policy based on the application feature information, wherein the control policy comprises a correspondence between the application feature information and an execution action;
• and
• process the service packet based on the execution action.
