Franz Rambach, Beate Konrad, Lars Dembeck, Ulrich Gebhard, Matthias Gunkel, Marco Quagliotti, Laura Serra, and Víctor López, "A Multilayer Cost Model for Metro/Core Networks," J. Opt. Commun. Netw. 5, 210-225 (2013)
A capital expenditure model is a key requirement to evaluate
multilayer (ML) metro and core network architectures. Based on the Internet
protocol/multiprotocol label switching (IP/MPLS), MPLS-transport profile,
optical transport network and WDM technology, a detailed capital expenditure
model developed by researchers from system vendors and network operators is
introduced. Besides current equipment and corresponding prices for the different
layers, it also contains predictions for technology evolution and pricing until
2018. We show how to determine the price of an ML node by constructing it from
components specified in the cost model. We use the model in a case study where
we benchmark the price of an
integrated IP/MPLS/WDM
solution.
