We present an application of sampling procedures in a distributed test and measurement system, which is able to provide real time and reliable end-to-end performance evaluations for packet broadband networks. The novel idea introduced in this work is the attempt to reduce the quantity of control data required to carry out the further management activities. Sampling is hence introduced for relieving the complexity of management functions, typically very complex in the current heterogeneous broadband networks. A simulation model of a “Passive QoS 2-point measurement system” working on an ATM network has been built and tested with a synthetic traffic as well as with a real ATM trace. Our results show the effectiveness of sampling in terms of the trade-off between the sampling rate, the attained estimation accuracy and the cost of taking measures (assumed to be proportional to the sample size).

Abstract
We present an application of sampling procedures in a distributed test and measurement system, which is able to provide real time and reliable end-to-end performance evaluations for packet broadband networks. The novel idea introduced in this work is the attempt to reduce the quantity of control data required to carry out the further management activities. Sampling is hence introduced for relieving the complexity of management functions, typically very complex in the current heterogeneous broadband networks. A simulation model of a “Passive QoS 2-point measurement system” working on an ATM network has been built and tested with a synthetic traffic as well as with a real ATM trace. Our results show the effectiveness of sampling in terms of the trade-off between the sampling rate, the attained estimation accuracy and the cost of taking measures (assumed to be proportional to the sample size).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
