Abstract

Method and apparatus for network-level anomaly inference in a network is described. In one example, link load measurements are obtained for multiple time intervals. Routing data for the network is obtained. Link level anomalies are extracted using temporal analysis on the link load measurements over the multiple time intervals. Network-level anomalies are inferred from the link-level anomalies.
