Abstract

The invention relates to a method and a system for traffic measurement in an ATM network. The bandwidth of a link (15) in the network is known. The traffic, i.e. bandwidth, is measured by letting the ATM cells enter and leave an imaginary buffer in a measuring device (30). In addition to the real cells, imaginary cells corresponding to an imaginary traffic stream are also entered into the imaginary buffer. If the bandwidth of the imaginary traffic is too large the imaginary buffer becomes full, cells are lost and an imaginary cell loss ratio is obtained. A predetermined imaginary cell loss ratio corresponds to utilising the total bandwidth of the link (15). The imaginary traffic corresponds to a known bandidth and by substracting the imaginary bandwidth from the bandwidth of the link (15) the bandwidth of the actual traffic is obtained.
