Abstract: A system identifies an intent policy model associated with an initial time. The system updates a data structure to cause the data structure to include one or more portions. Each portion of the data structure is associated with a start time and an end time. Each portion includes: a first delta snapshot that indicates one or more first changes to the intent policy model from the initial time to the start time associated with the portion, and one or more additional delta snapshots that respectively indicate one or more incremental changes to the intent policy model at times from the start time and to the end time associated with the portion of the data structure.

Abstract: A system identifies a source intent policy model that is associated with a graph having a plurality of source nodes connected by a plurality of source edges, identifies a set of source nodes of the plurality of source nodes, and translates the set of source nodes to generate a set of target nodes. The system identifies a subset of target nodes, of the set of target nodes, that are not included in a target intent policy model that is associated with a graph having a plurality of target nodes connected by a plurality of target edges. The system determines a hierarchical order associated with the subset of target nodes and the plurality of target node, and causes the target intent policy model to be updated to include the subset of target nodes and the plurality of target nodes, such that the graph is ordered according to the hierarchical order.

Abstract: A method includes receiving a plurality of configurations comprising a first configuration for provisioning a first set of network services at a first resource of an edge device and a second configuration for provisioning a second set of network services at the first resource, a first configuration group identifier identifying a configuration group for the first configuration, and a first network performance parameter for the configuration group. The method further includes determining a performance factor for the first resource providing the first set of network services to one or more client devices. The method further includes, in response to determining that the performance factor does not satisfy the first network performance parameter for the configuration group and that the first configuration group identifier identifies the configuration group for the first configuration, moving the first configuration from the first resource to a second resource of the edge device.

Abstract: A device may receive license data identifying device licenses and organization licenses associated with an organization of users of a multi-tenant system, and may identify, in the license data, entitlements for licenses associated with the organization. The device may combine the entitlements to generate combined entitlements, and may determine an entitlement count of the combined entitlements. The device may add quantities of new entitlements to the entitlement count, and may identify, in the license data, roles of the users and capabilities associated with each of the roles. The device may map the entitlements and the capabilities to generate a mapping, and may authorize a particular user based on the mapping. The device may process usage of the entitlements, with a machine learning model, to predict future usage of the entitlements, and may determine entitlement recommendations based on the future usage. The device may provide the entitlement recommendations for display.

Abstract: A controller device manages a plurality of network devices. The controller device includes one or more processing units configured to receive an indication of a stateful intent, the data structure including a plurality of nodes and a plurality of edges, each node of the plurality of nodes being representative of a respective network device of the plurality of network devices. The one or more processing units are configured to determine, using an abstract function configured at a node of the plurality of nodes, a stateless intent for implementing the stateful intent and generate low level configuration data for the plurality of network devices based on the stateless intent. The one or more processing units are configured to interface with one or more of the plurality of network devices to configure the one or more of the plurality of network devices with the low level configuration data.
