• In this paper an ATM call level model, where service classes with QoS guarantees(CBR/VBR)as well as elastic(best effort)services(ABR/UBR)coexist, is proposed and a number of simulations have been carried out on three different network topologies.Elastic traffic gives on the network level rise to new challenging problems since for a given elastic connection the bottleneck link determines the available bandwidth and thereby put constraints on bandwidth at other links.Thereby bandwidth allocation at call arrivals but also bandwidth reallocation at call departure becomes, together with routing, an important issue for investigation.Two series of simulation have been carried out where three different routing schemes have been evaluated together with two bandwidth allocation algorithms.The results indicate that the choice of routing algorithm is load dependent and in a large range the shortest path algorithm-properly adopted to the mixed CBR/ABR environment-performs very well.
