....policy, and the workload distribution. We compared several topology aggregation schemes that are di erent in terms of the accuracy of the routing information they provide. By means of the Z iteration method which numerically solves dynamic ow models of multi service connection oriented networks [11], we considered realistic skewed workloads as well as uniformly distributed workloads. Our simulation results led us to an interesting conclusion: under skewed workload, a less aggressive (and hence more costly) aggregation scheme, which results in a more detailed view of the network presented to ....

....show how to apply it to PNNI. The effect of different aggregation schemes on network performance is compared by simulation in [3] However, they do not investigate the effect of workload distribution. Our Results We obtain our results using our recently developed time dependent evaluation method [16]. We consider both skewed and uniform workloads. In a skewed workload, some nodes are selected as the destination of the majority of the connections (or calls) and are thus considered hot spots. In a uniform workload, sourcedetination node pairs are uniformly distributed over the network. Under ....

This model is solved using our recently developed timedependent evaluation method. The method solves dynamic flow models of multi service networks such as ATM see [16]. Section 3 discusses the computation and aggregation of routing metrics. Section 4 presents numerical results for a sample network. Section 5 concludes with future work. 2 Evaluation Model Network and Routing Models We consider a connection oriented network. To support real time QoS, necessary ....
