Abstract

It is described a network attack detection method. A topology analysis on network is conducted to obtain a probing path set containing at least one probing path. A first probing path contained in the probing path set is probed by using a probing pattern to obtain a performance metric of the first probing path. It is determined whether the first probing path is subjected to network attack according to the performance metric and a control performance metric.
