Abstract
This paper presents the design and implementation of a scheme for
accurate measurement of network bandwidth in xDSL networks, including
asymmetric upstream and downstream cases. A stepwise algorithm is
designed to minimize the effect on the measurements of ATM traffic
shaping for ABR and UBR service classes in xDSL deployments. The
accuracy of the algorithm is achieved by implementing an original
traffic generator with stable performance. Evaluation experiments have
demonstrated that the algorithm can achieve accurate bandwidth
measurement in xDSL networks
