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) 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: In general, techniques are described for automatic intent provisioning and management in computer networks. A device comprising a processor, a memory, and an interface may perform the techniques. The processor may obtain a policy that includes high-level configuration data defining a service to be deployed within a network, the high-level configuration data including resource selector criteria that identifies one or more criteria for selecting a resource to support the service from a plurality of potential resources. The processor may also determine, based on the resource selector criteria, the resource to support the service from the plurality of potential resources, and translate the high-level configuration data to low-level configuration data specific to the determined resource. The memory may store the low-level configuration data specific to the determined resource. The interface may enable configuration, when provisioning the service, the determined resource using the low-level configuration data specific to the determined resource.

Abstract: Techniques are disclosed for managing a network. In one example, a device configuration manager is configured to generate, in accordance with a device management protocol, a configuration change request representing a transaction having a first sub-transaction specifying a first configuration change for a network device of the network and a second sub-transaction specifying a second configuration change for the same network device. The device configuration manager is further configured to output the configuration change request to the network device and receive a reply message from the network device. The reply message includes a first response element specifying whether the first configuration change is successfully committed at the network device and a second response element specifying whether the second configuration change is successfully committed at the network device.

Abstract: In one example, a network management system (NMS) and method discovers device roles for network devices. The NMS includes a learning module configured to include a learning model, the learning model trained to associate configuration segments for each of a plurality of network devices with device roles performed by the network devices. The NMS discovers a network service on a network, receives configuration information from the discovered network service and splits the configuration information received from the discovered network service into configuration segments based on a vendor neutral yang model associated with the discovered network service. The NMS then determines if the discovered network service performs one or more of the device roles performed by the network devices used to train the learning model, wherein determining includes applying the learning model to the configuration segments of the discovered network service.

Abstract: A system and method for service discovery. A network management system constructs, based on configuration data associated with a first network device and a second network device, respectively, a first partial service instance associated with a service executing on a first network device and a second partial service instance associated with the service executing on a second network device. The network management system merges the first partial service instance and a second partial service instance to form a merged partial service instance. The network management system promotes the merged partial service instance as a service instance.

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.
