Abstract: This application provides a network device service quality detection method and apparatus. A service function feature of a network device is built into a service template as a fixed part. An operation and maintenance engineer does not need to learn of a service function feature of each network device, and only needs to provide information such as a flow identifier and deployment information that are of a to-be-detected service flow. A controller dynamically deploys a detection point according to the flow identifier and the deployment information of the service flow that are provided by the operation and maintenance engineer and the fixed part of the service template, so as to automatically detect service quality of a network device, and reduce operation and maintenance complexity and difficulties.
