Classification: CPC H | IPC H

Claim 15:
16. A non-transitory computer-readable storage medium comprising instructions that, when executed, cause one or more processors of a network management system to:
receive, from plurality of network devices operating as network gateways for an enterprise network, path data for a plurality of logical paths collected by each network device of the plurality of network devices for a respective one or more logical paths of a physical interface from a given network device over a wide area network (WAN);
compare one or more network performance metrics specified by the path data for each of the plurality of logical paths, including:
deriving, for each of the plurality of logical paths within a specified time window, one or more features of each of the one or more network performance metrics specified by the path data for each of the plurality of logical paths, and
generating a plurality of vectors, including generating, for each respective network performance metric of the one or more network performance metrics for each of the plurality of logical paths, a corresponding vector of values of the one or more features for the respective network performance metric:

determine, based on comparing the one or more network performance metrics, one or more outlier logical paths out of the plurality of logical paths; and
in response to determining the one or more outlier logical paths, output a notification indicative of the one or more outlier logical paths out of the plurality of logical paths.
