    Abstract: A path computation method and a related device are disclosed. The method includes: a second network device receives path requirement information and a recomputation condition that are sent by a first network device; the second network device first obtains by means of computation a path meeting a requirement according to the path requirement information, and sends description information of the path meeting the requirement to the first network device; then the second network device constantly determines whether the recomputation condition is met; and when the recomputation condition is met, the second network device performs path recomputation, and sends description information of a path obtained by means of recomputation to the first network device. Therefore sensitivity for triggering path recomputation can be improved and a quantity of communication messages between network devices can be reduced.

    Abstract: An embodiment of this application discloses a device management method. A first network management device may obtain subscription parameter information, where the subscription parameter information is used to indicate a subscription parameter used during a process of establishing a first subscription session, and the first subscription session is used to indicate a first network device to send subscription data to a network management device managing the first network device. After the first network management device determines that the first subscription session is interrupted, the first network management device may generate a request message based on the subscription parameter information, and send the request message to a network device managed by the first network management device.

    Abstract: This application discloses a network operation, administration, and maintenance (OAM) method, an apparatus, and a system. The method includes: receiving a fault alarm message sent by an MP, where the fault alarm message includes fault information; determining according to the fault alarm message, a first maintenance set to which the MP belongs, where the first maintenance set includes MPs using a first OAM technology; querying an OAM database, to obtain a second maintenance set interacting with the first maintenance set, where the second maintenance set includes MPs using a second OAM technology; and sending a fault notification message to all MPs in the second maintenance set or an MP that is determined according to a policy in the second maintenance set. Therefore, a related fault alarm may be centrally notified on a management plane, and is decoupled from a specific OAM technology, thereby greatly reducing an implementation difficulty.

    Abstract: A data processing method, apparatus, and system are disclosed. The method includes: A management device generates a request message, where the request message includes a quantity of list entries, identification information, and an offset. The management device sends the request message to a network device, where the request message is used to request, from the network device, a list entry that is in a list identified by the identification information, that uses the offset as a start location, and that is indicated by the quantity of list entries, and a total quantity of list entries included in the list is greater than the quantity of list entries. The management device receives a response message corresponding to the request message from the network device, where the response message includes a list entry requested by the request message.

    Abstract: This application discloses a device management method, apparatus, system, and device, and a storage medium. The method includes: obtaining, by a first network device, an extended YANG model file from a second network device, where the extended YANG model file includes a self-explanation tag, and the self-explanation tag is used to label network operation and maintenance data; obtaining the self-explanation tag from the extended YANG model file; and managing the second network device based on the self-explanation tag. The network operation and maintenance data is labeled by using the self-explanation tag. This facilitates device management such as data collection and is not prone to errors, thereby not only achieving relatively high management accuracy, but also improving management efficiency.
