Abstract: A controller device manages a plurality of network devices. The controller device includes one or more processing units configured to receive an upgrade request; obtain a redundancy model indicating network device redundancies or service redundancies; determine, based on the upgrade request and the redundancy model, an update graph having nodes each representing one of the network devices or one of the services, the update graph also having at least one edge that connects two of the nodes and that indicates the network redundancy or the service redundancy; determine, based on the update graph including the at least one edge, an update schedule for performing an update of software for the network devices that ensures availability for the first network device or second network device or availability for the service; and update the software of each of the network devices according to the update schedule.

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: 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: An example controller device manages a plurality of network devices. The controller device includes one or more processing units, implemented using digital logic circuitry, configured to receive data representing a modification to unified intent model represented by a graph model, determine one or more vertices of the graph model affected by the data representing the modification and one or more vertices to be added to the graph model to extend the unified intent model, update the one or more vertices of the graph model affected by the data representing the modification and add the one or more vertices to be added to the graph model, compile the updated one or more vertices and the added one or more vertices to generate low level configuration data for the plurality of network devices, and configure one or more of the plurality of network devices with the low level configuration data.

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.
