Abstract: In one example, a network management system (NMS) device manages a plurality of network devices. The NMS device includes a processor configured to determine a first set of differences between an existing high-level configuration for the plurality of network devices and a first received high-level configuration for the plurality of network devices, determine a second set of differences between the existing high-level configuration and a second received high-level configuration, wherein the second received high-level configuration is received separately from the first received high-level configuration, translate the first set of differences to a first low-level configuration modification, translate the second set of differences to a second low-level configuration modification, merge the first low-level configuration modification and the second low-level configuration modification, and apply the merged low-level configuration modification to low-level configuration of the plurality of network devices.

Abstract: In one example, a network management system (NMS) is configured to enable a target network device to support one more network services by generating a translation template to map a vendor neutral model to a device specific model. The NMS determines similarity scores between nodes in the vendor neutral model and nodes in the device specific model. Based on the similarity scores, the NMS generates a translation template from the vendor neutral model to the device specific model. Using the translation template, the NMS may configure the target network device to support the one or more network services.

Abstract: In one example, a network management system (NMS) device manages a plurality of network devices. The NMS device includes one or more interfaces to communicatively couple the NMS device to the plurality of network devices, and a processor, implemented using circuitry, configured to determine that a low-level configuration of a first network device of the plurality of network devices has been changed by an out-of-band (OOB) change, translate the OOB change to a high-level configuration change, determine whether to apply the high-level configuration change to the plurality of network devices, and in response to determining to apply the high-level configuration change to the plurality of network devices, apply, via the one or more interfaces, the OOB change to low-level configurations of the plurality of network devices.

Abstract: A system may receive network device configuration information associated with a network service. The system may determine multiple settings associated with the network service based on receiving the network device configuration information. The multiple settings may include a common setting and a device-specific setting. The system may generate a first network service model of the network service based on the multiple settings. The first network service model may include multiple nodes corresponding to the multiple settings. The system may re-configure one or more nodes associated with the first network service model, and may generate a second network service model of the network service. The system may generate a user interface template based on the second network service model and may provide the user interface template to a client device for display. The client device may allow a configuration of the multiple settings based on the user interface template.

Abstract: In one example, a network management system (NMS) is configured to enable a target network device to support a particular network service based on service configuration information for the particular network service. The service configuration information may include information about nodes in a vendor neutral model that need to be added or modified in order to support the particular network service. The NMS determines similarity scores between nodes in a vendor neutral model and nodes in a target device specific model. Based on the similarity scores, the NMS generates a mapping from the vendor neutral model to the target device specific model. Using the mapping, the NMS may configure a target device to support the particular service.

Abstract: 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.

Abstract: A system and method for service discovery. A network management system fetches, from a first network device, configuration data associated with a service executing on the first network device. In response to determining that the service extends across multiple network devices, the network management system constructs, based on the configuration data, a first partial service instance associated with the service executing on the first network device. The network management system merges a plurality of partial service instances to form a merged partial service instance, the plurality of partial service instances including the first partial service instance and a second partial service instance associated with the service executing on a different network device. The network management system promotes the merged partial service instance as a service instance.
