With the simulation approach, dimensioning is carried out by adapting the lub link bandwidth iteratively in order to reach a desired QoS in simulations. The dimensioning procedure has been explained with Figure 4.6 in Chapter 4.3. With the analytical approaches, the proposed M/G/R-PS models are applied. The analytical results are derived in accordance with the dimensioning procedures described in the last section. At first, the accuracy of the analytical approaches with the M/G/R-PS models is validated by simulations to dimension a 6 Dimensioning for Single ATM-Based lub single link to meet a desired delay factor as the QoS target. For analyzing the dimensioning results, different dimensioning metrics are evaluated (definitions of various dimensioning metrics are referred to section 4.3). After validations, the analytical approaches are applied to investigate the dimensioning rules for elastic traffic for a desired application QoS. Validation of Analytical Approaches for Dimensioning First of all, a dimensioning example is given, which investigates the applicability of the proposed M/G/R-PS model for dimensioning a single lub link. In this example, there is only elastic traffic which is generated from the web application with a constant page size of 50 kbyte. All elastic traffic flows are transmitting with the same peak rate of 128 kbps (RAB 128 kbps) and no CAC is applied to elastic traffic. The QoS target is to achieve a delay factor of = =1.25. Figure 6.37 shows the required lub link capacity (in kbps) over different traffic loads in terms of link throughput (in kbps). The theoretical results are derived with the dimensioning procedure for the case of single RAB without applying CAC, i.e. with the extended M/G/R
