Abstract:We explore alternative architectures to reduce cost of IP-over-Optical Core networks. We conducted a detailed cost study of three architectures. We start with a Baseline architecture that captures present mode of operations (PMO) with future traffic projections and utilizes technologies such as Ethernet line-cards (LCs) and OTN sub-wavelength switching. The next architecture, Streamlined, replaces the hub-and-spoke topology of Baseline with a flat topology and is also more judicious in its restoration design. … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
