Application degradation root causing and rerouting using time series clustering

Abstract

In one embodiment, a device forms clusters of network paths via which traffic for an online application is conveyed by applying clustering to time series of quality of experience metrics for the online application. The device calculates, for a particular cluster of network paths among the clusters of network paths, correlation metrics between path features of those network paths of that cluster. The device selects, based on the correlation metrics, a particular path feature from among the path features as a root cause of poor quality of experience metrics for the online application along the network paths of the particular cluster of network paths. The device provides, to a user interface, an indication of the particular path feature as being the root cause of poor quality of experience metrics for the online application.
