Abstract
Runtime detection of network loops is performed. It is detected when for a network segment a ratio of duplicate packets to total packets exceeds a first predetermined threshold. Also it is detected when traffic load on the network segment exceeds a second predetermined threshold. When the ratio of duplicate packets to total packets exceeds the first predetermined threshold and the traffic load on the network segment exceeds the second predetermined threshold, a network loop has been detected.
