In this paper we present a new method for the detection of bottleneck link(s) in the networks. The proposed method is based on the variance-per-mean ratio of the flow's through put crossing the link which can be calculated from the data trace information provided by passive traffic monitoring. This new indicator of bottleneck links is found to be ef fective and robust against the offered link loads, bottleneck bandwidth, and the traffic composition. The results are ver ified using both simulation and real measurement analysis.
