Abstract: In one example, a network management system (NMS) device manages a plurality of network devices. The NMS device includes a processor configured to determine a first set of differences between an existing high-level configuration for the plurality of network devices and a first received high-level configuration for the plurality of network devices, determine a second set of differences between the existing high-level configuration and a second received high-level configuration, wherein the second received high-level configuration is received separately from the first received high-level configuration, translate the first set of differences to a first low-level configuration modification, translate the second set of differences to a second low-level configuration modification, merge the first low-level configuration modification and the second low-level configuration modification, and apply the merged low-level configuration modification to low-level configuration of the plurality of network devices.

Abstract: In one example, a network management system (NMS) device manages a plurality of network devices. The NMS device includes one or more interfaces to communicatively couple the NMS device to the plurality of network devices, and a processor, implemented using circuitry, configured to determine that a low-level configuration of a first network device of the plurality of network devices has been changed by an out-of-band (OOB) change, translate the OOB change to a high-level configuration change, determine whether to apply the high-level configuration change to the plurality of network devices, and in response to determining to apply the high-level configuration change to the plurality of network devices, apply, via the one or more interfaces, the OOB change to low-level configurations of the plurality of network devices.

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: Some implementations described herein relate to a system that is configured to obtain one or more event logs associated with a tenant of the system. The system may be configured to determine, based on the one or more event logs, an event rate associated with the tenant and thereby determine, based on the event rate, a rotation interval. The system may be configured to cause, based on the rotation interval, a data structure to be generated for storing event logs associated with the tenant that are obtained during a time window. The system may be configured to obtain, within the time window, one or more additional event logs associated with the tenant and to cause, based on obtaining the one or more additional event logs within the time window, the one or more additional event logs to be stored in the data structure.

Abstract: Network management techniques are described. A controller device of this disclosure manages a device group of a network. The controller device includes processing circuitry in communication with the memory, the processing circuitry being configured to receive, using a programmable diagnosis service executed by the processing circuitry, a programming input, to form, using the programmable diagnosis service, based on the programming input, a resource definition graph that models interdependencies between a plurality of resources supported by the device group, to detect, using the programmable diagnosis service, an event affecting a first resource of the plurality of resources, and to identify, using the programmable diagnosis service, based on the interdependencies modeled in the resource definition graph formed based on the programming input, a root cause event that caused the event affecting the first resource, the root cause event occurring at a second resource of the plurality of resources.

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 method includes maintaining, by a controller device that manages a plurality of network devices, a data structure and receiving, by the controller device, an indication of a stateful intent. The method further includes generating, by the controller device, a logical packet based on the stateful intent and determining, by the controller device, a dependent intent of the data structure based on the logical packet. The method further includes determining that the dependent intent conflicts with the stateful intent. The method further includes, in response to determining that the dependent intent conflicts with the stateful intent, determining, by the controller device, a resolution that resolves the conflict between the dependent intent and the stateful intent based on the dependent intent and the stateful intent and outputting, by the controller device, an indication of the resolution.
