Abstract: A method for managing a plurality of network devices of a network includes determining, by one or more processors, a causality map for the plurality of network devices according to an intent. The method further includes receiving, by the one or more processors, an indication of a network service impact and determining, by the one or more processors, a relevant portion of the causality map based on the network service impact. The method further includes determining, by the one or more processors, one or more candidate root cause faults based on the relevant portion of the causality map and outputting, by the one or more processors, an indication of the one or more candidate root cause faults.

Abstract: A controller device includes a memory and one or more processors coupled to the memory. The memory stores instructions that, when executed, cause the one or more processors to receive, from a set of sensor devices, first telemetry data indicating a first set of changes for telemetry parameters that occur during a first time range. The instructions further cause the one or more processors to determine, using the first snapshot and the first telemetry data, a second snapshot that specifies a first complete state at an end of the first time range. The instructions further cause the one or more processors to determine a second complete state of the telemetry parameters for the second time range based on the second snapshot and second telemetry data indicating a second set of changes for the set of telemetry parameters that occur during a second time range.
