Abstract: In a configuration management process, a configuration commission request sent by a client to a server includes an identifier of a specified data source. The server, even if configuration data in a candidate configuration datastore comes from a plurality of data sources, does not commit all configuration data that comes from data sources other than the specified data source in the plurality of data sources to a running configuration datastore. That is, some configuration data that is not expected to be committed is not forced to be committed when configuration data from a data source needs to be committed.

Abstract: Embodiments of this application disclose a configuration update method, apparatus, and system, and a computer-readable storage medium, and pertain to the field of communication technologies. In the embodiments of this application, when a specific client performs configuration update on a network device, the client may send a NETCONF configuration request message to the network device without locking a data object; and the network device performs configuration update on the data object if the network device detects that version information, of the data object, respectively recorded by the client and the network device is consistent. Alternatively, the client sends a NETCONF configuration request message to the network device if detecting that version information, of the data object, respectively recorded by the client and the network device is consistent.

Abstract: Embodiments of this application disclose a query method and apparatus, and a device. The network management device generates a query message, where the query message includes a query condition, and the query condition is used to determine a first mapping relationship between license information and information about a YANG model object. The network management device sends the query message to a first device. The network management device receives a response message obtained by the first device based on the query condition, where the response message includes the first mapping relationship.

Abstract: The present invention relates to an apparatus and a method for validating application deployment topology in a cloud environment. There is provided an apparatus for validating application deployment topology in a cloud environment comprising: a topology skeleton generator configured to generate, based on multiple VMs and script packages running on the VMs created by a user and required to deploy an application as well as running order of script packages and data dependency between script packages set by the user, a topology skeleton that comprises at least scripts of script packages of respective VMs and running order of the script packages; and a simulator configured to simulate a runtime environment in the cloud environment at the apparatus, thereby validating the running order and data dependency with respect to the topology skeleton, wherein the simulator is installed in the apparatus by using a simulator installation package retrieved from the cloud environment.

Abstract: A method and device for processing at least one of routing status and policy information is provided. The method includes: a routing or forwarding system receives a first request for establishing a connection sent by a SDN control client, and the first request carries an identifier of the SDN control client; the routing or forwarding system establishes a corresponding relationship between at least one of routing status and policy information sent by the SDN control client and the identifier; and the routing or forwarding system manages at least one of the routing status and policy information according to the corresponding relationship.
