This paper evaluates different architectures for multilayer IP transport networks. The evaluation is based on an exemplary network dimensioning of a reference IP backbone network topology, connecting 63 points of presence (PoPs) in Germany. The network dimensioning results are used for a techno-economic analysis of the different network architectures, taking into account hypothetical but realistic...
Optical systems and technologies have been radically changing the telecommunication networks for past 15 years; today wavelength division multiplexing (WDM) technology, optical amplifiers, and simple optical switching elements like optical add-drop multiplexers (OADMs) are used in the backbone networks of all operators worldwide. Optical systems nowadays provide the basis for cost-effective transmission...
