Abstract: In one embodiment, a method includes receiving network data at an analytics device, grouping features of the network data into multivariate bins, generating a density for each of the multivariate bins, computing a rareness metric for each of the multivariate bins based on a probability of obtaining a feature in a bin and the probability for all other of the multivariate bins with equal or smaller density, and identifying anomalies based on computed rareness metrics. An apparatus and logic are also disclosed herein.

Abstract: The disclosed technology relates to intent driven network management. A system is configured to maintain an inventory store comprising records for a set of network entities in a network, wherein each network entity in the set of network entities is associated with a record in the inventory store. The system receives a user intent statement comprising an action and a flow filter representing network data flows on which the action is to be applied and queries, based on the flow filter, the inventory store to identify a plurality of network entities in the set of network entities to which the user intent statement applies. The system generates a plurality of network policies that implement the user intent statement based on the plurality of network entities and the action and enforces the plurality network policies.
