Abstract: An example controller device that manages a plurality of network devices includes one or more processing units implemented in circuitry and configured to: obtain device-level configuration information from a network device of the plurality of network devices at a first time; determine one or more out-of-band (OOB) configuration changes between the device-level configuration information from the network device and previous device-level intent configuration information compiled from one or more intents maintained by the controller device to manage the plurality of network devices; and store the one or more OOB configuration changes associated with the network device in incremental deltas.

Abstract: Scalable, robust cloud-based network management systems (NMSs) are described. In one, an NMS includes a set of NMS applications, a pool of device communication managers (DCMs), and a pool of device operations managers (DOMs). Each of the DCMs and DOMs executed by the processors as software containers. The NMS includes an API gateway configured to route remote procedure calls (RPCs) from the DCMs to the DOMs via the APIs exposed by the DOMs and according to device identifiers of the managed elements. The DOMs are configured to establish a set of persistent application-layer communication sessions from the DOMs to the DCMs and to direct communications from the NMS applications to the DCMs over the persistent application-layer communication sessions according to a mapping between device identifiers associated with the managed elements and network addresses associated with the DCMs.

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.
