Abstract: A fault localization method includes: obtaining user experience data, network topology data, and resource management data that are of a video service; where the network topology data is used to represent a connection relationship between network devices, and the resource management data is used to represent a connection relationship between user equipment and the network devices; determining a QoE experience indicator of a network device based on the user experience data, the network topology data, and the resource management data; and when QoE represented by the QoE experience indicator of the network device is lower than QoE represented by a device screening threshold, determining the network device as a possible questionable device.

Abstract: A fault localization method and device are provided. The method includes: obtaining user experience data, network topology data, and resource management data that are of a video service; where the network topology data is used to represent a connection relationship between network devices, and the resource management data is used to represent a connection relationship between user equipment and the network devices; determining a quality of experience (QoE) experience indicator of a network device based on the user experience data, the network topology data, and the resource management data; and when quality of experience represented by the QoE experience indicator of the network device is lower than quality of experience represented by a device screening threshold, determining the network device as a possible questionable device. According to the embodiments of the present invention, accuracy of fault localization is high.

Abstract: Embodiments of the present invention disclose a method for switching an NC link, a processor system, and a node, where the processor system includes more than two nodes capable of communicating with each other, each node includes a node controller NC chip, a host bus adapter HBA apparatus, and at least one CPU, the NC chip is connected to each CPU in a node where the NC chip is located, and the HBA apparatus is connected to each CPU in a node where the HBA apparatus is located; an NC link borne by the NC chip is corresponding to an HBA link borne by the HBA apparatus. By using an HBA apparatus to deploy a redundant link, the cost of deploying the redundant link is reduced effectively under a premise of ensuring the reliability of the processor system.
