Comparison of the VP, CVP and VN approaches in ATM network design

This paper compares three ATM network design options in terms of the required link capacities and traffic flows for specified GoS and QoS requirements. The design options are referred to as: (i) end-to-end VP design; (ii) concatenated VP design; and (iii) VN design. Numerical results are presented for various large-scale networks and traffic conditions which demonstrate the cost-effectiveness of the VN design approach relative to the other design options.
