摘要： Techniques are described for dynamically adapting virtualized network functions (VNFs) to different target environments. A controller stores device profiles that include configuration data and workflows for resolving configuration parameters for instantiating and deploying a VNF package to form a network service. To support the resolution of VNF configuration parameters, a VNF descriptor for the VNF is extended to include a device family parameter that indicates a shared architecture and configuration parameters. The controller, when instantiating the VNF, may identify a device profile usable for resolving the configuration parameters for the VNF and obtain configuration data from the device profile for creating and configuring a VNF instance for the VNF descriptor. Extending the VNF descriptor to specify a device family allows the VNF to be flexibly adapted for different target environments and may avoid the use of numerous pre-defined VNF descriptors.

摘要： In general, techniques are described for providing data consistency for managed device data among network managers in a hierarchical and distributed network management system in which the network managers operate according to a microservices-based software architecture. For example, a method comprises receiving a data model for a network device, wherein the data model comprises an object and an annotation that indicates a type of scope for the object; and processing, based on the object and annotation, the data model to generate application code for a microservice application for a network manager for managing instances of the network device, wherein the application code, when compiled, and executed by the network manager, causes the network manager to replicate data associated with the object to one or more of a plurality of network managers of a distributed network managed system.

摘要： A system receives discovery rule inputs that include addresses, verifies one or more device identifiers for one or more addresses, obtains device information from each verified device associated with the one or more verified device identifiers, determines whether each verified device is a discovered device based on the device information, and automatically adds each verified device as a discovered device to a management system without human intervention when it is determined that the verified device is discovered. The system further creates device configuration information, creates an identifier and password, provides device configuration information, the identifier, and the password, to each of the discovered devices based on the NETCONF or the Device Management Interface standards, waits for a connection from the discovered devices, imports device configuration information from the discovered devices when the connection has been established, and indicates that the discovered devices are managed devices.

摘要： In one example, a network management system (NMS) device manages a plurality of network devices including first and second network devices. Initially the first and second network devices are configured according to a first high-level configuration. The NMS is configured to determine a difference between the first high-level configuration and a second high-level configuration, apply a first transformation function, specific to the first network device, to the difference to generate a first low-level configuration change specific to the first device, apply a second transformation function, specific to the second network device, to the difference to generate a second low-level configuration change specific to the second device, configure the first device with the first low-level configuration change, and configure the second device with the second low-level configuration change.
