Bandwidth Measurement in xDSL Networks
نویسندگان
چکیده
This paper presents a 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 of ATM traffic shaping for ABR and UBR service classes in xDSL deployments on the bandwidth measurements. 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.
