摘要： This application discloses a troubleshooting method. In the method, a controller first determines that a fault occurs on a first multi-layer link passing through a first port on a first network device, where the first multi-layer link is a link in a link aggregation group between the first network device and a second network device; the controller then releases an optical layer resource of the first multi-layer link, and deletes the first multi-layer link from the link aggregation group; and the controller further establishes, a second multi-layer link for restoration of the first multi-layer link, based on a first idle port on the first network device and a second idle port on a target network device, and adds the second multi-layer link to a target link aggregation group between the first network device and the target network device. According to this method, a faulty link in an aggregation group can be restored in a multi-layer network.

摘要： This application discloses a fault protection method for an optical network. A cross-layer controller connecting an optical network and an IP network sends, to an optical controller in the optical network, an indication that a first optical service in an optical fiber belongs to a first priority and a second optical service in the optical fiber belongs to a second priority. The first priority is related to a feature of the first IP link in the IP network, and the second priority is related to a feature of the second IP link in the IP network. When the optical fiber is faulty, a protected priority of any optical service belonging to the first priority is higher than a protected priority of any optical service belonging to the second priority. In the method, the cross-layer controller sends, to the optical controller, indication information indicating that different optical services belong to different priorities. When the optical network is faulty, the optical controller determines protected sequence of the different optical services based on the priorities. Therefore, random behavior during fault protection for the optical network is avoided, and targeted fault protection is provided for the optical network.
