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: Network elements are managed with a server to support client data models from heterogeneous data sources. A server receives a first query for configuration data of a network element to be returned in a first model. The server determines a model type for the configuration data of the network element. When the model type is a second model that is not the first model, the server sends a second query to the network element for the configuration data to be returned in the second model and transforms the configuration data received from the network element into the first model. Additionally, the server returns the configuration data in the first model as a response to the first query.

Abstract: A controller device manages a plurality of network devices. The controller device includes one or more processing units implemented in circuitry and configured to determine that one or more stateless intents of a deployed graph model including a first set of stateless intents used to manage the plurality of network devices have changed, wherein stateless intents comprise fully declarative descriptions of an intended state of a network including the network devices, state of one or more of the network devices, or state of storage for the network; maintain both the deployed graph model and an undeployed graph model including a second set of stateless intents including the one or more changed stateless intents; compile the changed stateless intents of the undeployed graph model to generate low-level configuration data for the network devices; and configure the network devices using the low-level configuration data.

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: Management of network devices using network aware diagnosis techniques. An example method to monitor a network includes constructing, by a controller device that manages a plurality of network devices, a deployed graph model comprising a plurality of models representative of services operating on the network devices within the network. The method also includes receiving an alert, by the controller device, that a service operating on one of the network devices is experiencing a failure. Additionally, the method includes traversing, by the controller device, modeled dependencies within the deployed graph model to perform root cause analysis of the service that is experiencing the failure to determine a resource-level event causing the failure. The method includes. based on the traversing, providing, by the controller device, a report indicating the root cause of the failure.

Abstract: In one example, a network management system discovers a plurality of network devices behind a network address translation device, such as a firewall. The network management system may receive a model of a seed network device, generate a first activation configuration and commit the first activation configuration on the seed network device. The network management system may connect to the seed network device and discover neighboring devices from information in the seed network device. The network management system may connect to the neighboring devices, automatically create a model of the neighboring network devices, generate s activation configurations for the neighboring network devices and commit the activation configurations on the neighboring network devices. The network management system may iterative perform these steps until it discovers all the discoverable network devices behind the network address translation device.
