Research output: Contribution to journalArticlepeer-review


An optimum design scheme is proposed for VC network topologies on a Flexible Multi-QoS Logical ATM Network, named Full-Net. Full-Net offers high-quality Virtual-Path (VP) networks and controls end-to-end QoS only at the VP-networks access points. To develop the optimum network topology for multimedia traffic in a single ATM network, a logically configured Virtual Channel Handler (VCH) interconnection network is associated with each QoS class. To achieve an optimum design scheme for VC networks, the number of disjoint routes is introduced as the parameter used to optimize VC network topology. The number of disjoint routes is chosen so as to maximize total network efficiency. The optimum number of disjoint routes depends on the required QoS, VC-traffic characteristics, and traffic demand.
