    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: The present application describes a path selection method and apparatus. The method may include obtaining a required latency of a service. The method may further include determining a target path for the service from m strict explicit paths based on the required latency, where a latency of the target path is less than or equal to the required latency, all the m strict explicit paths are unallocated paths, any subpath of a first strict explicit path in the m strict explicit paths exists in only the first strict explicit path, the first strict explicit path is any path in the m strict explicit paths, and m is an integer greater than or equal to 1. The present invention is applicable to the field of communications technologies and resolves at least a problem where a path computation element (PCE) cannot ensure that a path allocated to a service can meet a latency requirement of the service.

    Abstract: The present invention provides a virtual network function network element management method, apparatus, and system. A VNF resource pool management apparatus receives a VNF network element request message sent by a VNF resource pool user apparatus, where the VNF network element request message includes attribute information and a location policy of a VNF network element that is requested; the VNF resource pool management apparatus determines a first VNF network element that matches the attribute information and the location policy from the VNF resource pool; and the VNF resource pool management apparatus sends a VNF network element response message to the VNF resource pool user apparatus, where the VNF network element response message includes identification information of the first VNF network element. In this way, a risk that a functional group formed by VNF network elements cannot properly work can be avoided.

    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 device management method includes a first network device sending a first remote procedure call (RPC) request message to a second network device, where the first RPC request message includes information about a third yet another next generation (YANG) module that is identifiable to the first network device. After the second network device switches to the third YANG module, the first network device establishes a control session between the first network device and the second network device based on the third YANG module. When the network device supports switching between YANG modules of different standards, the second network device is notified, by using an RPC, to switch to a YANG module supported by the first network device.

    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.
