Comparison of IP/WDM transport network architectures for dynamic data traffic (Invited)

In this paper, we outline key IP/WDM transport network architectures and present a framework for their comparison regarding resource requirements under dynamic data traffic. For enabling our dimensioning process by taking statistical multiplexing into account, we apply effective bandwidth theory to translate traffic demands with highly variable traffic characteristics into the required transport capacity. Finally, we use this framework to analyze the node and network resources for a German reference backbone network scenario with realistic traffic dynamics from traffic measurements.
