Publication number: 20240097983Abstract: 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.Type: ApplicationFiled: December 22, 2022Publication date: March 21, 2024Inventors: Chandrasekhar A, Jayanthi R, Premchandar N

Publication number: 20230195858Abstract: 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.
