    Abstract: A service fault locating method and apparatus for precisely locating a network fault problem in a multi-layer OAM architecture network. The method includes: receiving a service fault locating request message; determining, an IPS, and an IPD, that a service fault is between a first layer-3 device and a second layer-3 device; obtaining a first network topology between the first layer-3 device and the second layer-3 device; determining a first forwarding path of the service packet between the first layer-3 device and the second layer-3 device according to the first network topology; configuring a forwarding entry of a forwarding device in the first forwarding path, and triggering the first layer-3 device to generate an extended layer-2 OAM packet; and obtaining a first path parameter of the first forwarding path, and determining a specific location of the service fault according to the first path parameter.

    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.
