Abstract: Embodiments of this application provide a method for subscribing to event streams. The method includes: A first device generates a first message used to subscribe to event streams, where the first message includes a group identifier, and the group identifier corresponds to a plurality of event streams; and the first device sends the first message to a second device, to obtain data of the plurality of event streams corresponding to the group identifier.

Abstract: A first server device obtains first device information of the first server device. The first device information may include an event or a device identifier. The first server device determines a first condition corresponding to the first device information of the first server device, and performs a first processing action corresponding to the first device information when determining that the first device information meets the first condition.

Abstract: A packet transmission method is applied to a communication device including a first MPU, a second MPU, and an LPU. The first MPU is connected to the LPU through a first transmission channel. The second MPU is connected to the LPU through a second transmission channel. During packet transmission, a service flow packet is transmitted through the first transmission channel, and a non-service flow packet is transmitted through the second transmission channel. Therefore, the service flow packet and the non-service flow packet are processed by different MPUs, so that the service flow packet and the non-service flow packet do not compete with each other. In this way, transmission efficiency of the non-service flow packet is improved. In addition, when the first MPU is attacked by an abnormal service flow packet, the second MPU is not affected, and may normally perform operation and maintenance management.

Abstract: Embodiments of this application disclose a data obtaining method. A first device serving as a network management device may generate a first message including a first keyword. The first message is used to indicate a second device to determine a first path in which the second device stores a parameter determined by the first keyword, and send the first path to the first device. The second device may be a device managed by the first device. Then, the first device may send the first message to the second device. After receiving the first message, the second device may determine the first path in which the second device stores the parameter determined by the first keyword, add the determined first path to a second message, and send the second message to the first device.

Abstract: A first device generates a first capability model instance based on a capability model template, and sends the first capability model instance to a network management device. The capability model template includes one or more metric names. The first capability model instance includes one or more performance parameters that can be subscribed to by the first device, and the one or more performance parameters are parameters corresponding to one or more metric names. The first capability model instance is used by the network management device to select and subscribe to one or more performance parameters from the one or more performance parameters that can be subscribed to by the first device.

Abstract: A data processing method includes: A network management device generates an extended ECA instance. The extended ECA instance includes a first event, a first condition, and a first action, the first action includes a first object identifier and a first indicator type, the first object identifier indicates a first to-be-monitored object, the first indicator type indicates a performance indicator of the first to-be-monitored object, the extended ECA instance is used to indicate a network device managed by the network management device to send first monitoring data to the network management device based on the first event and the first condition, and the network device includes the first to-be-monitored object. Then, the network management device sends a first message to the network device, where the first message includes the extended ECA instance.
