Asymmetric digital subscriber line (ADSL) is becoming a relatively matured technology as many telecommunication service providers offer this technology to customers. The actual throughput of ADSL is highly dependent on the number of simultaneous users within a cable grouping. In order to guarantee throughput to any user at any time, one must be able to predict the circumstances under which throughput cannot be guaranteed any more. To guarantee high reliability of these predictions, a reliable theoretical model of the system is required. A comparison is made between the theoretical model and the practical scenario to determine the accuracy of the theoretical model. It was found that the theoretical model closely resembles the practical scenario, which makes QoS estimation possible using a theoretical model, rather than a trial-and-error method.
